Title: Medical device and method of delivering the medical device

Description:
BACKGROUND 
     Field 
     This application is a Nonprovisional of, and claims priority to, U.S. Patent Application No. 61/870,027, filed Aug. 26, 2013, entitled “MEDICAL DEVICE AND METHOD OF DELIVERING THE MEDICAL DEVICE”, which is incorporated by reference herein in its entirety. 
    
    
     The present invention generally relates to medical devices and procedures, and particularly, devices configured to be delivered and placed in a patient&#39;s body for the treatment of pelvic floor disorder and methods thereof. 
     Description of the Related Art 
     Pelvic organ prolapse is an abnormal descent or herniation of the pelvic organs. A prolapse may occur when muscles and tissues in the pelvic region become weak and can no longer hold the pelvic organs in place correctly. 
     Treatment for symptoms of the pelvic organ prolapse can include changes in diet, weight control, and lifestyle. Treatment may also include surgery, medication, and use of grafts to support the pelvic organs. 
     Sacrocolpopexy is one such surgical technique that may be used to repair pelvic organ prolapse. This can be performed using an open abdominal technique or with the use of minimally invasive surgery, such as laparoscopy or robotic-assisted surgery. The technique includes suspension of the apical portion of vagina (or sometimes the vaginal cuff after hysterectomy) using an implant such that the technique tries to recreate the natural anatomic support. 
     In some cases, a Y-shaped implant may be used to treat vaginal vault prolapse during the sacrocolpopexy procedure. The Y-shaped implant aids vaginal cuff suspension to the sacrum and provides long-term support. The procedure can be minimally invasive (laparoscopic sacral colpopexy) or traditional (open sacral colpopexy). Also, in some cases, different anatomical locations inside a patient&#39;s body for example, vagina, uterus, and sacrum may be involved in repair of the pelvic organ prolapse. For example, at least a portion of the implant may be attached to an anterior vaginal wall, and a posterior vaginal wall in some cases. These anatomical locations have different biological attributes and behave differently. Therefore, the implant may not conform to the varying behavior of the different anatomical locations where the implant portions are attached. 
     Thus, in light of the above, there is a need for an improved implant that can be fabricated to conform to varying behavior of different anatomical locations inside a patient&#39;s body. 
     SUMMARY 
     In an embodiment, the invention discloses an implant. The implant may include a first flap and a second flap. The first flap may further include a first portion, a second portion and a transition region. The first portion may be configured to be attached proximate a sacrum. The second portion may be configured to be attached to an anterior vaginal wall. The transition region lies between the first portion and the second portion. The second flap may be fabricated such that a portion of the second flap is configured to be attached to a posterior vaginal wall. The implant may be configured such that a value corresponding to a biomechanical parameter defining a biomechanical attribute of the portion of the first flap attaching to the anterior wall is different from a value of the biomechanical parameter defining the biomechanical attribute of the portion of the second flap attaching to the posterior wall. 
     In an embodiment, the invention discloses a tubular implant. The tubular implant includes a first portion, a second portion, and a transition region. The first portion of the tubular implant can be configured to be attached proximate a sacrum. The transition region can extend from the first portion. The second portion can extend from the transition region monolithically. The second portion includes a first section and a second section and two slits provided laterally in the second portion configuring the first section as apart from the second section at a proximal end. The tubular implant further includes a lumen defined within the first and second portions of the tubular implant. The tubular implant can be configured such that the first section is configured to be attached to an anterior vaginal wall, and the second section is configured to be attached to a posterior vaginal wall. 
     In an embodiment, the invention discloses a method for placing an implant in a body of a patient. The method includes inserting the implant inside the body. The method further includes attaching a portion of the implant to an anterior vaginal wall, wherein the portion attaching to the anterior vaginal wall defines a first value of a biomechanical parameter defining a biomechanical attribute. The method further includes attaching a portion of the implant to a posterior vaginal wall. The portion attaching to the posterior vaginal wall defines a second value of the biomechanical parameter such that the second value corresponding to the portion attaching to the posterior wall is different from the first value corresponding to the portion attaching to the anterior wall.

       FIG. 1  is a schematic diagram of an implant  100 . The implant  100  can include a first flap  102 . The first flap  102  can include a first portion  104 , a second portion  106  and a transition region  108 . In an embodiment, the implant  100  can be used for the treatment of a pelvic floor disorder. In some embodiments, the implant  100  can be used to suspend various bodily locations in a body of a patient. For example, in some embodiments, the implant  100  can be used to suspend a pelvic organ of a patient&#39;s body. In some embodiments, the implant  100  can be a part of a retropubic incontinence sling. In some embodiments, the implant  100  can be configured to be delivered by way of a transvaginal approach or a transobturator approach or vaginal pre-pubic approach or a laparoscopic approach or can be delivered through other approaches and positioned at various locations within a patient&#39;s body. 
     The first portion  104  defines a first side  110 , a second side  112 , a proximal portion  114  and a distal portion  116 . The proximal portion  114  can be attached to or extend from the transition region  108  of the first flap  102 . The distal portion  116  can be configured to be attached to a first bodily tissue. In some embodiments, the first bodily tissue can be a sacrum or tissue proximate a sacrum of a patient. In some embodiments, the first bodily tissue can be any one of lumbar vertebra, tail bone, and illium portion of hip bone inside the patient&#39;s body. In some embodiments, the first bodily tissue can be any other location inside the patient&#39;s body. 
     The first portion  104  defines a length L 1  along the first side  110  extending from the proximal portion  114  to the distal portion  116 . The first portion  104  defines a length L 2  along the second side  112  extending from the proximal portion  114  to the distal portion  116 . In some embodiments, the length L 1  can be equal to the length L 2 . In some embodiments, the length L 1  can be different from the length L 2 . The first portion  104  defines a width W 1  extending between the first side  110  and the second side  112 . In some embodiments, the width W 1  can remain constant from the proximal portion  114  to the distal portion  116 . In some embodiments, the width W 1  can differ from the proximal portion  114  to the distal portion  116 . 
     The first bodily tissue exhibits a definite biomechanical behavior in a defined set of physical conditions. The first portion  104  can be configured to define a set of biomechanical attributes or biomechanical properties so as to emulate the biomechanical behavior of the first bodily tissue, where at least a portion of the first portion  104  is required to be attached, in the defined set of physical conditions. The biomechanical attributes for the first bodily tissue can be defined by a first set of values of respective biomechanical parameters associated with each of the biomechanical attributes. For example, in some embodiments, the biomechanical attribute can be elasticity and a corresponding biomechanical parameter can be modulus of elasticity which can be defined by a numerical value. While the use of a modulus (such as a modulus of elasticity) is used to measure a biomechanical parameter, it should be understood that the biomechanical parameter of the bodily tissue may also be directly measured. For example, in some embodiments, the elasticity of the bodily tissue maybe measured (without using a modulus). In some embodiments, the biomechanical attribute can be stiffness. In some embodiments, the biomechanical attribute can be strength. In some embodiments, the biomechanical attribute can be resistance to creep. In various embodiments, the biomechanical attributes of the first portion  104  can be defined for example by defining one or more of shape, size, fabrication method, structure, profile, knit structure, pore size, material of fabrication, fiber orientation, and the like. In some embodiments, for example, the congruence between the biomechanical behavior of the first bodily tissue and the first portion  104  can be achieved by varying the shape of the first portion  104 . For example, the first portion  104  can have a square, rectangular, triangular or any other shape, which can facilitate the first portion  104  in closely equating the biomechanical behavior of the first bodily tissue. 
     In some embodiments, the biomechanical attributes of the first portion  104  can be defined by a first type of knit structure (not shown here and explained later). In some embodiments, the first type of knit structure can be defined by first type of knitting pattern (not shown here and explained later). In some embodiments, the first type of knit structure can be defined by a first type of pore construct. In some embodiments, the first type of knit structure can be defined by weaving the knit with a required and defined tension. For example, the first knitting pattern can be woven tightly or loosely to define required type of knitting pattern. In some embodiments, the first knitting pattern characterized by biomechanical properties of high elastic modulus and stiffness can facilitate holding onto bodily tissue such as the vagina, the vaginal apex, or a sacrum in the correct anatomical location. The different ways of achieving the desirable biomechanical attributes for the first portion  104  of the first flap  102  can be used in isolation or in combination. It must be appreciated that though the above ways of defining the required biomechanical attributes are used for mesh-based implants  100  including a knit pattern, the implant  100  can be fabricated as a planar structure. In such embodiments, the biomechanical attributes of the first portion  104  of the first flap  102  of the implant  100  can be defined for example by the material used in fabrication of the first portion  104 , shape and size of the portion, and the like without limitations. For example, a rigid medical grade polymer can be used for fabricating the first portion  104  thereby defining the biomechanical attribute of rigidity for the first portion  104  to a desired value. 
     In some embodiments, reinforcements such as reinforcement fibers may be woven into portions of the implant  100 . In some embodiments, the implant  100  may include elastic fibers woven into portions of the implant  100 . 
     The second portion  106  defines a first side  118 , and a second side  120 , a proximal portion  122  and a distal portion  124 . The distal portion  124  can be attached to or extend from the transition region  108  of the first flap  102 . The proximal portion  122  can be configured to be attached to a second bodily tissue. In some embodiments, the second bodily tissue can be an anterior vaginal wall inside a patient&#39;s body. In some embodiments, the second bodily tissue can be at least one of a posterior vaginal wall, a uterus, and a vaginal apex. In some embodiments, the second bodily tissue can be any other location inside the patient&#39;s body. 
     The second portion  106  defines a length L 3  along the first side  118  extending from the proximal portion  122  to the distal portion  124 . The second portion  106  defines a length L 4  along the second side  120  extending from the proximal portion  122  to the distal portion  124 . In some embodiments, the length L 3  can be equal to the length L 4 . In some embodiments, the length L 3  can be different from the length L 4 . The second portion  106  defines a width W 2  extending between the first side  118  and the second side  120 . In some embodiments, the width W 2  can remain constant from the proximal portion  122  to the distal portion  124 . In some embodiments, the width W 2  can differ from the proximal portion  122  to the distal portion  124 . In some embodiments, the second portion  106  is fabricated such that the width W 2  of the second portion  106  is greater than the width W 1  of the first portion  104 . In some embodiments, the second portion  106  can define a trapezoidal shape such that the width W 2  at the proximal portion  122  is substantially greater than the width W 2  at the distal portion  124 . In some embodiments, the second portion  106  can have a polygonal shape. In some embodiments, the second portion  106  can have a square, rectangular, triangular or any other shape. 
     The second bodily tissue exhibits a definite biomechanical behavior in a defined set of physical conditions. The behavior exhibited by the second bodily tissue can be different than the behavior exhibited by the first bodily tissue. The second portion  106  can be configured to define the biomechanical attributes or biomechanical properties so as to emulate the biomechanical behavior of the second bodily tissue in the defined set of physical conditions. The biomechanical attributes can be defined by a second set of values of respective biomechanical parameters associated with each of the biomechanical attributes. Consequently, the second portion  106  may be defined to exhibit values of the biomechanical attributes, different than the values of the biomechanical attributes of the first portion  104 , in accordance with the second bodily tissue where at least a portion of the second portion  106  of the first flap  102  may be attached. It must be appreciated that in some embodiments, only one or more but not all of the first set of values biomechanical attributes and the second set of values differ in terms of their values of parameters defining the respective attributes. For example, the modulus of elasticity may be same for the first portion  104  and the second portion  106  but any other parameter for other attribute such as resistance to creep may be different. In some other embodiments, all the attributes of the first portion  104  and the second portion  106  may differ in terms of their numerical values of parameters defining the respective attributes. 
     In some embodiments, the second set of values associated with the biomechanical attributes can be different along different directions for the same fixed set of physical conditions even for the same attribute. For example, in some embodiments, a value of a parameter P defining an attribute T along a first direction A 1  can be different from a value of the parameter P defining the attribute T along a second direction A 2 . In some embodiments, the first direction A 1  can be a longitudinal direction and the second direction A 2  can be a transverse or perpendicular direction. In other embodiments, the first direction can be disposed at a non-transverse or non-perpendicular angle with respect to the second direction. 
     In some embodiments, the thread diameter, and/or the thread count may contribute to the different the biomechanical attributes. In some embodiments, the thickness of the mesh may contribute to the different biomechanical attributes. In some embodiments, the sides or edges of the mesh may have rough surfaces or projecting fibers. 
     It must be appreciated that the biomechanical behavior of the bodily tissues and the biomechanical attributes of the various portions of the implant  100  may change owing to change in physical conditions. Therefore, for the purpose of comparing the various biomechanical behaviors and the biomechanical attributes, a reasonably sufficient amount of similarity in physical conditions may be assumed to an extent that a change in the conditions creates an ignorable influence. However, in other embodiments, the physical conditions may vary and measurement of the biomechanical behavior and the attributes may accordingly be calibrated so as to compare the various values associated with the various attributes in light of the required characteristics at the required locations. For example, the stiffness of the first portion  104  and the second portion  106  may be different initially during fabrication but since the physical conditions at the respective bodily tissues may be different, therefore the initial values of the stiffness may not remain same after placement. This change due to variation in the physical conditions may be considered while defining the attributes of the respective portions of the implant  100  so as to achieve the desired set of attributes with the desired set of values. 
     In some embodiments, the biomechanical attributes can include elasticity and a corresponding biomechanical parameter can be modulus of elasticity. In some embodiments, the biomechanical attribute can be viscoelasticity. In some embodiments, the biomechanical attribute can be viscohyperelasticity. In some embodiments, the biomechanical attribute can be anisotropic. In various embodiments, the biomechanical attributes of the second portion  106  can be defined by defining one or more of shape, size, fabrication method or structure, profile, knit structure, pore size, material of fabrication, and the like. In some embodiments, for example, the congruence between the biomechanical behavior of the second bodily tissue and the second portion  106  can be achieved by varying the shape of the second portion  106 . For example, the trapezoidal shape of the second portion  106  can conform to shape of the second bodily tissue such as the anterior vaginal wall inside a patient&#39;s body. 
     In some embodiments, the biomechanical attributes of the second portion  106  can be defined a second type of knit structure (not shown here and explained later). In some embodiments, the second type of knit structure can be defined by second type of knitting pattern (not shown here and explained later). In some embodiments, the second type of knit structure can be defined by weaving the knit with a required and defined tension. For example, the anterior vaginal wall shows anisotropic biomechanical behavior, with a bias toward more elongation along a transverse direction (or non-transverse direction), therefore, the second type of knitting pattern can be selected so as to be more elastic along a longitudinal direction as compared to the transverse direction. 
     In some embodiments, the second type of knit structure can be defined by a second type of pore construct. In some embodiments, the second type of pore construct is different from the first type of pore construct. In some embodiments, the second pore construct includes a larger pore size as compared to a pore size of the first pore construct. In some embodiments, the difference in pore constructs of the first and second portions  104  and  106  can be achieved by knitting or weaving a mesh with different pore sizes. In some embodiments, the difference in pore constructs for the first and second portions  104  and  106  can be achieved by extruding a single pore size mesh and heat setting the pores to set a different pore size for the first and second portions  104  and  106  as illustrated and described by later figures. The second pore construct can define the second set of values of the biomechanical attributes of the second portion  106 . In an embodiment, the second pore construct can define larger pore sizes as compared to the remaining portion of the implant  100 . In some embodiments, the second pore construct can be fabricated to exhibit biomechanical attributes of high flexibility and elongation to a particular strain level and high stiffness after the particular stain level is reached. Such a strain behavior may closely emulate the biomechanical behavior of the vaginal wall for example the anterior vaginal wall. Therefore, the second pore structure defines the biomechanical attributes so as to conform to the biomechanical behavior of the second bodily tissue that is the vaginal wall. 
     In some embodiments, the apertures formed by the mesh material may be of any shape or size. In some embodiments, embodiments, the mesh material may be formed in more than one portion or strip rather than a single portion. In some embodiments, the mesh material may include a coating or covering. In some embodiments, the fibers of the mesh may be disposed at any angle with respect to other fibers of the mesh. In some embodiments, the fibers are woven perpendicular to other fibers of the mesh. In other embodiments, the fibers are woven at different angles. In some embodiments, the mesh may be compress or annealed. 
     In some embodiments, the values associated with the biomechanical attributes can be defined by a material used for fabricating the second portion  106 . For example, a viscoelastic medical grade polymer can be used for fabricating the second portion  106  thereby defining a value for the biomechanical attribute of viscoelasticity for the second portion  106 . In some embodiments, an anisotropic medical grade polymer can be used for achieving a desired anisotropic value. In some embodiments, a creep resistant medical grade polymer can be used for achieving a desired value of creep resistance. 
     In some embodiments, the first bodily tissue can be stiffer and the second bodily tissue can be flexible, therefore the first portion  104  in such cases can be configured with the biomechanical attributes congruent with high stiffness and the second portion  106  with high flexibility. Similarly, in other embodiments, other attributes may be associated according to the behavior of the respective bodily tissues. The different ways of achieving the desirable values for the biomechanical attributes for the first portion  104  and the second portion  106  as discussed above can be used in isolation or in combination. 
     In some embodiments, for example, the second bodily tissue can be the anterior vaginal wall. Various examples of attributes possibly needed to be considered for defining the portions of the first flap  102  that are attached to the anterior vaginal wall can without limitations be viscoelasticity, viscohyper-elasticity, resistance to creep and anisotropy, and the like. 
     The first flap  102  further includes the transition region  108  as mentioned above. The transition region  108  defines a proximal portion  126  and a distal portion  128 . The proximal portion  126  of the transition region  108  can be coupled to or extend from the distal portion  124  of the second portion  106 . The distal portion  128  of the transition region  108  can be coupled to or extend from the proximal portion  114  of the first portion  104 . In some embodiments, the transition region  108  may define a third type of knit structure (not shown here and explained later) that monolithically joins the first portion  104  and the second portion  106 . In some embodiments, the third knit structure may define a third type of pore construct (not shown here and explained later). In some embodiments, the first flap  102  can be formed by suturing together the first portion  104  and the second portion  106 . In such cases, the transition region  108  includes sutures tying the first portion  104  and the second portion  106 . 
     In some embodiments, the implant  100  further includes a second flap (not shown in  FIG. 1 ). The second flap can include a first portion, a second portion and a transition region. The first portion and the transition region of the second flap can function the same way as that of the first flap  102  and can be defined in a similar manner. The first portion can be attached to the first bodily tissue proximate to a location where the first portion  104  of the first flap  102  is attached. The second portion of the second flap can be configured to be attached to a third bodily tissue. In some embodiments, the third bodily tissue can be a posterior vaginal wall inside a patient&#39;s body. The third bodily tissue exhibits a definite biomechanical behavior in a defined set of physical conditions. The second portion can define the biomechanical attributes so as to emulate the biomechanical behavior of the third bodily tissue, where at least a portion of the first portion of the second flap is required to be attached, in the defined set of physical conditions. The biomechanical attributes can be defined by a third set of values corresponding to respective biomechanical parameters associated with the biomechanical attributes. The second portion of the second flap can be configured so that at least one of the biomechanical parameters of the second portion  106  of the first flap and the second portion of the second flap differ in their numerical values. For example, the stiffness behavior of the anterior vaginal wall can be different from the posterior vaginal wall; therefore the second portion  106  of the first flap  102  and the second portion of the second flap can be fabricated to exhibit stiffness attributes different from each other. 
     In some embodiments, the implant  100  can be configured such that each of the first flap  102  and the second flap define strips of material and can be configured to be attached separately to bodily locations. In some embodiments, each of the first flap  102  and the second flap are constructed from a single piece of material. In some embodiments, the first flap  102  and the second flap are fabricated independent of each other. In some embodiments, the implant  100  can be formed from a mesh material. In some embodiments, the implant can be formed from a non-mesh material. 
     In some embodiments, the implant  100  can be Y-shaped. The Y-shaped implant can include three portions—a first portion configured to be attached to the sacrum or tissues proximate to the sacrum, a second portion configured to be attached to the anterior vaginal wall, a third portion configured to be attached to the posterior vaginal wall. In some embodiments, the Y-shaped implant  100  can be fabricated so as to include either of the first flap  102  and the second flap as described above and another flap which may be either a conventional strip of implant material or any of the first flap and the second flap above. For example, in an embodiment, the Y-shaped implant can be fabricated by using the first flap and the second flap and coupling them together to provide a Y-shape to the implant. During fabrication a portion of the first and/or second flaps may be removed to configure the implant in the Y-shape. For example, at least one of the first portion of the first flap and the first portion of the second flap can be removed. In another embodiment, the Y-shaped implant can be fabricated by using one of the first flap and the second flap and another conventional flap such that the conventional flap can be coupled to the other of the first or the second flap to configure the implant in the Y-shape. In still another embodiment, the Y-shape can be achieved by using various portions of the first flap and the second flap and a conventional implant strip. In some embodiments, the biomechanical attributes of the three portions of the Y-shaped implant can be defined based on the biomechanical behavior of the three locations of the body where the three portions of the implant are configured to be attached. In other embodiments, the implant has a shape other than a Y-shape. For example, the implant could be rectangular, square, or any other shape. Additionally, in some embodiments, the implant has more than one portion, such as more than one separate portion. For example, the implant may have two, three or more separate portions or pieces. 
     In some embodiments, the implant  100 , or the first flap  102  or the second flap can be cut from a prefabricated structure including the first portion  104  with the first type of knit structure and the second portion  106  with the second type of knit structure. In some embodiments, the implant  100  can be fabricated by coupling different strips of materials each defining a set of biomechanical attributes congruent with biomechanical behavior of respective anatomical locations where they are placed inside a patient&#39;s body. The strips can take a shape such as linear or planar, curvilinear, curved, or any other shape. 
     In some embodiments, the first flap  102  and the second flap can be monolithically defined as a single piece such as in the form of a tubular structure (not shown here and explained later). The tubular structure can include a first portion, a transition region and a second portion. The first portion can be configured to be attached proximate the sacrum inside a patient&#39;s body. In some embodiments, the first portion can be similar to the first portion of the first flap described above in terms of biomechanical attributes. The transition region extends from the first portion. In some embodiments, the second portion of the tubular structure can function in a manner similar to the way the second portion of the first flap and the second portion of the second flap together perform. For example, an upper circumferential section of the second portion of the tubular structure can function similar to the function of the second portion of the first flap and the lower circumferential section of the tubular structure can function similar to the second portion of the second flap. In an embodiment, the second portion of the tubular structure can be configured to be cut by an operator to convert it into two sections. The sections though may still be joined at a medial portion or proximate the transition region. In some embodiments, two slits may be provided along two lateral edges of the tubular structure to define the two flaps for the two different bodily tissues. The slits can be made by an operator or may be predefined. 
     In some embodiments, the procedure of placing the implant  100  within a body can be performed after performing hysterectomy and removal of uterus from the body. In some other embodiments, the implant  100  can be placed even when the uterus is intact. The first flap  102  and the second flap can be attached inside the patient&#39;s body through various attachment elements or means. In some embodiments, the attachment elements include, without limitations, sutures, adhesives, bonding agents, mechanical fasteners (e.g. a medical grade plastic clip), staples, and the like. In some embodiments, the implant  100  can be sutured to bodily tissues with the use of a suturing device such as a Capio™ (as sold and distributed by Boston Scientific Corporation) and the like. In some embodiments, the implant  100  can be delivered inside a patient&#39;s body using any suitable insertion tool such as a needle or any other device. In some embodiments, a dilator may be attached to the implant  100  to deliver the implant  100  inside the patient&#39;s body. 
     In various embodiments, as discussed above, the implant  100  is made of a single piece of material. In some embodiments, the material is synthetic. In some embodiments, the implant  100  includes a polymeric mesh body. Exemplary polymeric materials are polypropylene, polyester, polyethylene, nylon, PVC, polystyrene, and the like. In some other embodiments, the implant  100  includes a polymeric planar body without mesh cells. In some embodiments, the implant  100  is made of a mesh body made of a non-woven polymeric material. An example of the mesh, out of which the implant  100  is formed, can be Polyform® Synthetic Mesh developed by the Boston Scientific Corporation. The Polyform® Synthetic Mesh is made from uncoated monofilament macro-porous polypropylene. Typically, the surface of the implant  100  is made smooth to avoid/reduce irritation on adjacent body tissues during medical interactions. Additionally, the implant  100  is stretchable and flexible to adapt movements along the anatomy of the human body and reduce suture pullout. Furthermore, softness, lightness, conformity, and strength are certain other attributes that can be provided in the implant  100  for efficient tissue repair and implantation. In some embodiments, the implant  100  can be made of natural materials such as biologic material or a cadaveric tissue and the like. Exemplary biologic materials are bovine dermis, porcine dermis, porcine intestinal sub mucosa, bovine pericardium, a cellulose based product, cadaveric dermis, and the like. 
     In some embodiments, different portions of the implant may be configured to display or have different biomechanical profiles. For example, in some embodiments portions of the implant may include a coating, such as a silicone coating that may impart or provide elasticity factors to the portions of the implant. The coating may also secure or help prevent the fibers or filaments of the implant from moving with respect to each other. In some embodiments, the coating may be configured to degrade or partially degrade once disposed within the body of the patient. In some embodiments, portions of the implant may be annealed or softened with respect to other portions of the implant. The annealing or softening can be done in patterns to provide or impart anisotropic characteristics. For example, in some embodiments, heat, radiation, or chemicals may be used to anneal or soften portions of the implant. 
     In some embodiments, some filaments of the implant can be treated with glue or an adhesive or can be welded to an adjacent filament. Such gluing or welding can provide different characteristics to the different portions of the implant. In some embodiments, different materials may be used to form the different portions of the implant. The different materials may be configured to display and provide different characteristics to the different portions of the implant. In some embodiments, the different portions of the implant may include more filaments or more twists or have a different knit or weave pattern. 
     In some embodiments, the implant includes a reinforcing fiber or a plurality of reinforcing fibers. The reinforcing fiber or fibers may be disposed at specific locations or extend along a particular direction to provide different characteristics to the different portions of the implant. 
     In some embodiments, the implant includes flat or planar sheets of material. The sheets of material may have different pore quantities or distributions to provide different characteristics at different portions of the implant. In some embodiments, the implant may include laminated materials. For example, a mesh material may be coupled to or otherwise disposed adjacent to a sheet material. Additionally, one sheet material may be coupled to or otherwise disposed adjacent to another sheet material. 
     In some embodiments, a portion or portions of the implant may be weakened to provide different characteristics to different portions of the implant. For example, in some embodiments, portions of the implants may be notched, scored, grooved or shaved to introduce weakness or to weaken different portions of the implant. 
       FIG. 2  is a perspective view of a first flap  248  of a medical implant  200  for placement over an anterior wall of a vagina inside a patient&#39;s body. The first flap  248  can include a first portion  202 , a second portion  204  and a transition region  206 . 
     The first portion  202  defines a first side  208 , a second side  210 , a proximal portion  212  and a distal portion  214 . The proximal portion  212  can be attached to or extend from the transition region  206  of the first flap  248 . The distal portion  214  can be configured to be attached to a first bodily tissue. In some embodiments, the first bodily tissue can be a sacrum inside a patient&#39;s body. The first portion  202  defines a length L 5  along the first side  208  extending from the proximal portion  212  to the distal portion  214 . The first portion  202  defines a length L 6  along the second side  210  extending from the proximal portion  212  to the distal portion  214 . In some embodiments, the length L 5  can be equal to the length L 6 . The first portion  202  defines a width W 3  extending between the first side  208  and the second side  210 . In some embodiments, the width W 3  can remain constant from the proximal portion  212  to the distal portion  214 . 
     In some embodiments, the first flap  248  can be configured so that the first portion  202  can be attached to the sacrum or tissues proximate the sacrum and the remaining portion of the first flap  248  can be attached to the anterior vaginal wall in order to provide support to the anterior vaginal wall. 
     The first bodily tissue exhibits a definite biomechanical behavior in a defined set of physical conditions. The first portion  202  can be configured to define a set of biomechanical attributes or biomechanical properties so as to emulate the biomechanical behavior of the first bodily tissue, where at least a portion of the first portion  202  is required to be attached, in the defined set of physical conditions. The biomechanical attributes can be defined by a first set of values of respective biomechanical parameters associated with the biomechanical attributes. For example, in some embodiments, the biomechanical attribute can be elasticity and a corresponding biomechanical parameter can be modulus of elasticity, which can be defined by a numerical value. In some embodiments, the biomechanical attribute can be stiffness. In some embodiments, the biomechanical attribute can be strength. In some embodiments, the biomechanical attribute can be resistance to creep. In various embodiments, the biomechanical attributes of the first portion  202  can be defined by defining one or more of shape, size, fabrication method or structure, profile, knit structure, pore size, material of fabrication, and the like. In some embodiments, for example, the congruence between the biomechanical behavior of the first bodily tissue and the first portion  202  can be achieved by varying the shape of the first portion  202 . For example, the first portion  202  can have a square, rectangular, triangular or any other shape, which can facilitate the first portion  202  in closely equating the biomechanical behavior of the first bodily tissue. 
     In some embodiments, the values of the biomechanical attributes of the first portion  202  can be defined by a first type of knit structure  216 . In some embodiments, the first type of knit structure  216  can be defined by a first type of knitting pattern  218 . In some embodiments, the first type of knit structure  216  can be defined by weaving or knitting the knit with a required and defined tension. For example, the first type of knitting pattern  218  can be woven or knitted tightly or loosely to define a required type of knitting pattern. In some embodiments, the first type of knitting pattern  218  characterized by biomechanical properties of high elastic modulus and stiffness can hold bodily tissue such as a vaginal tissue in the correct anatomical location. In some embodiments, the first type of knit structure  216  can be defined by a first type of pore construct  220 . The first type of pore construct  220  includes a plurality of pores  222 . The first type of pore construct  220  can be fabricated to define biomechanical attributes conforming to biomechanical behavior of the first bodily tissue by varying the first type knit structure  216 , and the pore construct  220 . The different ways of achieving the desirable biomechanical attributes for the first portion  202  of the first flap  248  can be used in isolation or in combination. In some embodiments, the knit structure includes knitting, weaving, braiding, twisting, tying, or any combination thereof. 
     It must be appreciated that though the above ways of defining the required biomechanical attributes are used for mesh-based implants  200  including a knit pattern, the implant  100  can be fabricated as a planar structure. In such embodiments, the biomechanical attributes of the first portion  202  of the first flap  248  can be defined for example by the material used in fabrication of the first portion  202 , shape and size of the portion, and the like without limitations. For example, a rigid medical grade polymer can be used for fabricating the first portion  202  thereby defining the biomechanical attribute of rigidity for the first portion  202  to a desired value. 
     The second portion  204  defines a first side  224 , and a second side  226 , a proximal portion  228  and a distal portion  230 . The distal portion  230  can be attached to or extend from the transition region  206  of the first flap  248 . The proximal portion  228  can be configured to be attached to the second bodily tissue. In some embodiments, the second bodily tissue can be an anterior vaginal wall inside a patient&#39;s body. 
     The second portion  204  defines a length L 7  along the first side  224  extending from the proximal portion  228  to the distal portion  230 . The second portion  204  defines a length L 9  along the second side  226  extending from the proximal portion  228  to the distal portion  230 . In some embodiments, the length L 7  can be different from the length L 9 . The second portion  204  defines a width W 4  extending between the first side  224  and the second side  226 . In some embodiments, as illustrated, the width W 4  can differ from the proximal portion  228  to the distal portion  230 . In some embodiments, the second portion  204  is fabricated such that the width W 4  is greater than the width W 3  of the first portion  202 . In some embodiments, the second portion  204  can define a trapezoidal shape such that the width W 4  at the proximal portion  228  is substantially greater than the width W 4  at the distal portion. The second portion is configured to be attached and provide support to a second bodily tissue. 
     The second bodily tissue exhibits a definite biomechanical behavior in a defined set of physical conditions. The behavior exhibited by the second bodily tissue can be different than the behavior exhibited by the first bodily tissue. The second bodily tissue can be configured to define a set of biomechanical attributes or biomechanical properties so as to emulate the biomechanical behavior of the second bodily tissue in the defined set of physical conditions. The biomechanical attributes can be defined by a second set of values of respective biomechanical parameters associated with each of the biomechanical attributes. The second set of values can be different from the first set of values. Consequently, the second portion  204  may be defined to exhibit values of the biomechanical attributes, different than the values of the biomechanical attributes of the first portion  202 , in accordance with the second bodily tissue where at least a portion of the second portion  204  of the first flap  248  may be attached. It must be appreciated that in some embodiments, only one or more but not all of the first set of values biomechanical attributes and the second set of values differ in terms of their values of parameters defining the respective attributes. For example, the modulus of elasticity may be same for the first portion  202  and the second portion  204  but any other parameter for other attribute such as resistance to creep may be different. In some other embodiments, all the attributes of the first portion  202  and the second portion  204  may differ in terms of their values of parameters defining the respective attributes. The values of the various parameters provide mathematical measures of the respective parameters. 
     In some embodiments, the second set of values associated with the biomechanical attributes can be different along different directions for the same fixed set of physical conditions even for the same attribute. For example, in some embodiments, a value of a parameter P defining an attribute T along a first direction B 1  can be different from a value of the parameter P defining the attribute T along a second direction B 2 . In some embodiments, the first direction B 1  can be a longitudinal direction and the second direction B 2  can be a transverse direction. Therefore, a parameter may differ in its value in different directions, in some embodiments. For example, modulus of elasticity of various portions of the first flap  248  may differ in different directions, in some embodiments. This may be important to match the biomechanical behavior of bodily tissues that may exhibit different levels of elasticity in different directions. Also, the second set of values associated with the biomechanical attributes can vary with a variation in the set of physical conditions. However, in some embodiments, the physical conditions may vary and measurement of the biomechanical behavior and the attributes may accordingly be calibrated so as to compare the various values associated with the various attributes in light of the required characteristics at the required locations. In some embodiments, the first direction B 1  and the second direction B 2  do not align along the axes of the implant. Additionally, in some embodiments, B 1  and B 2  are not disposed orthogonal or perpendicular to one another. 
     In some embodiments, the biomechanical attributes can include elasticity and a corresponding biomechanical parameter can be modulus of elasticity. In some embodiments, the biomechanical attribute can be viscoelasticity. In some embodiments, the biomechanical attribute can be viscohyperelasticity. In some embodiments, the biomechanical attribute can be anisotropicity. In various embodiments, the biomechanical attributes of the second portion  204  can be defined by defining one or more of shape, size, fabrication method or structure, profile, knit structure, pore size, material of fabrication, and the like. In some embodiments, for example, the congruence between the biomechanical behavior of the second bodily tissue and the second portion  204  can be achieved by varying the shape of the second portion  204 . For example, the trapezoidal shape of the second portion  204  can conform to the shape of the second bodily tissue such as the anterior vaginal wall. The trapezoidal shape can be provided to the second portion  204  to emulate a taper of an outer vaginal canal. In some embodiments, at the widest end, the width W 4  can range from 21.7-55 mm. In some embodiments, at the narrowest end, the width W 4  can range from 18.7-37 mm. The lengths L 6  or L 8  of the trapezoid can range from 40.8-95 mm based on the linear length of the vagina. 
     In some embodiments, the values of the biomechanical attributes of the second portion  204  can be defined by a second type of knit structure  232 . In some embodiments, the second type of knit structure can be defined by a second type of knitting pattern  234 . In some embodiments, the second type of knit structure  232  can be defined by weaving the knit with a required and defined tension. For example, the anterior vaginal wall shows anisotropic behavior, with biasness toward more elongation along a transverse direction such as the direction B 1 , therefore, the second type of knitting pattern  234  can be selected so as to be more elastic along a longitudinal direction such as the direction B 2  as compared to the transverse direction. 
     In some embodiments, the second type of knit structure  232  can be defined by a second type of pore construct  236 . In some embodiments, the second type of pore construct  236  is different from the first type of pore construct  220 . The second type of pore construct  236  includes a plurality of pores  238 . In some embodiments, the difference in pore construct for the first portion  202  and the second portion  204  can be achieved by weaving or knitting a mesh with different pore sizes. In some embodiments, the difference in pore constructs  220  and  236  of the first portion  202  and the second portion  204  can be achieved by extruding or knitting a single pore size mesh and heat setting the pores to set a different pore size for the first portion  202  and the second portion  204  as illustrated and described by later figures. The second pore construct  236  can define the second set of values of the biomechanical attributes of the second portion  204 . In an embodiment, the second pore construct  236  can define larger pore sizes as compared to the remaining portion of the first flap  248 . In some embodiments, the second pore construct  236  can be fabricated to exhibit biomechanical attributes of high flexibility and elongation to a particular strain level and high stiffness after a particular stain level is reached. Such a strain behavior closely emulates the biomechanical behavior of the anterior vaginal wall. 
     In some embodiments, one or more of the biomechanical attributes can be defined by a material used for fabricating the second portion  204 . For example, a viscoelastic medical grade polymer can be used for fabricating the second portion  204  thereby defining a value for the biomechanical attribute of viscoelasticity for the second portion  204 . In some embodiments, an anisotropic medical grade polymer can be used for achieving a desired value of anisotropicity. In some embodiments, the desired value of ansiotropicity may be achieved though the process of forming the device or portion of the device. In some embodiments, a creep resistant medical grade polymer can be used for achieving a desired value of creep resistance. 
     Generally, the anterior vaginal wall can be viscohyperelastic. The second portion therefore can be defined such that it exhibits high viscoelasticity. In some embodiments, the biomechanical parameters can have different values in different directions. For example, the biomechanical parameters may have different values in the first direction B 1  than in the second direction B 2 . 
     The values of the biomechanical parameters defining the biomechanical behavior of the anterior vaginal wall may vary under different load conditions. For example, in some embodiments, the stiffness of the anterior vaginal wall at a low strain along the direction B 1  can range from 0.431-4.15 MegaPascal (MPa). In some embodiments, the stiffness of the anterior vaginal wall at a high strain along the direction B 1  can range from 5.15-17.28 MPa. In some embodiments, the stiffness the anterior vaginal wall at the low strain along the direction B 2  can range from 0.385-0.415 MPa. In some embodiments, the stiffness of the anterior vaginal wall along the direction B 2  at the high strain can range from 0.370-0.61 MPa. The stiffness behaviors of the anterior vaginal wall are further explained in detail in conjunction with  FIGS. 6A and 6B . Therefore, in some embodiments, the second portion  204  of the first flap  248  can be fabricated so as to define a set of values of the biomechanical parameter of stiffness that can conform to the values defining the biomechanical behavior of the anterior vaginal wall under similar load conditions. 
     The first flap  248  further includes the transition region  206  as mentioned above. The transition region  206  defines a proximal portion  240  and a distal portion  242 . The proximal portion  240  can be coupled to or extend from the distal portion  230  of the second portion  204 . The distal portion  242  can be coupled to or extend from the proximal portion  212  of the first portion  202 . In some embodiments, the transition region  206  may define a third type of knit structure  244  that monolithically joins the first portion  202  and the second portion  204 . In some embodiments, the third knit structure  244  may define a third type of pore construct  246 . In some embodiments, the first flap  248  can be formed by suturing together the first portion  202  and the second portion  204 . In such cases, the transition region  206  includes sutures tying the first portion  202  and the second portion  204 . 
       FIG. 3  is a perspective view of a second flap  340  of the medical device  200  for placement over a posterior wall of a vagina inside a patient&#39;s body. The first flap  248  and the second flap  340  can collectively form the medical implant  200 . The second flap  340  can include a first portion  302 , a second portion  304  and a transition region  306 . 
     The first portion  302  defines a first side  308 , a second side  310 , a proximal portion  312  and a distal portion  314 . The proximal portion  312  can be attached to or extend from the transition region  306  of the second flap  340 . The distal portion  314  can be configured to be attached to a first bodily tissue. In some embodiments, the first bodily tissue can be a sacrum or tissues proximate the sacrum. The first portion  302  defines a length L 9  along the first side  308  extending from the proximal portion  312  to the distal portion  314 . The first portion  302  defines a length L 10  along the second side  310  extending from the proximal portion  312  to the distal portion  314 . In some embodiments, the length L 9  can be equal to the length L 10 . The first portion  302  defines a width W 5  extending between the first side  308  and the second side  310 . In some embodiments, the width W 5  can remain constant from the proximal portion  312  to the distal portion  314 . 
     In some embodiments, the second flap  340  can be configured so that the first portion  302  can be attached to the sacrum and the remaining portion of the implant  300  can be attached to the posterior vaginal wall in order to provide support to the posterior vaginal wall. The first bodily tissue exhibits a definite biomechanical behavior in a defined set of physical conditions. The first portion  302  can be configured to define a set of biomechanical attributes or biomechanical properties so as to emulate the biomechanical behavior of the first bodily tissue, where at least a portion of the first portion  302  is required to be attached, in the defined set of physical conditions. The first portion  302  of the second flap  340  can be fabricated similar to the first portion  202  of the first flap  248  as described in  FIG. 2 . The attributes of the first portion  302  of the second flap  340  can be defined in a manner similar to the attributes of the first portion  202  of the first flap  248 . 
     The second portion  304  defines a first side  316 , and a second side  318 , a proximal portion  320  and a distal portion  322 . The distal portion  322  can be attached to or extend from the transition region  306  of the second flap  340 . The proximal portion  320  can be configured to be attached to a third bodily tissue. In some embodiments, the third bodily tissue can be the posterior vaginal wall. 
     The second portion  304  defines a length L 11  along the first side  316  extending from the proximal portion  320  to the distal portion  322 . The second portion  304  defines a length L 12  along the second side  318  extending from the proximal portion  320  to the distal portion  322 . In some embodiments, the length L 11  can be different from the length L 12 . The second portion  304  defines a width W 6  extending between the first side  316  and the second side  318 . In some embodiments, as illustrated, the width W 6  can differ from the proximal portion  320  to the distal portion  322 . In some embodiments, the second portion  304  is fabricated such that the width W 6  is greater than the width W 5  of the first portion  302 . In some embodiments, the second portion  304  can define a trapezoidal shape such that the width W 6  at the proximal portion  320  is substantially greater than the width W 6  at the distal portion  322 . 
     The third bodily tissue exhibits a definite biomechanical behavior in a defined set of physical conditions. The behavior exhibited by the third bodily tissue can be different than the behavior exhibited by the first bodily tissue or the second bodily tissue. The third bodily tissue can be configured to define the biomechanical attributes or biomechanical properties so as to emulate the biomechanical behavior of the third bodily tissue in the defined set of physical conditions. The biomechanical attributes can be defined by a third set of values of respective biomechanical parameters associated with the biomechanical attributes. In some embodiments, the third set of values can be different from the first set of values of the biomechanical attributes. In some embodiments, the third set of values can be different from the second set of values of the biomechanical attributes. Consequently, the second portion  304  may be defined to exhibit biomechanical attributes, different than the biomechanical attributes of the first portion  302 , in accordance with the third bodily tissue where at least a portion of the second portion  304  may be attached. The second portion  304  may be defined to exhibit biomechanical attributes, different than the biomechanical attributes of the first portion  202  from the first flap  248 . 
     In some embodiments, the third set of values associated with the biomechanical attributes can be different along different directions for the same fixed set of physical conditions even for the same attribute. For example, in some embodiments, a value of a parameter P defining an attribute T along a first direction C 1  can be different from a value of the parameter P defining the attribute T along a second direction C 2 . In some embodiments, the first direction C 1  can be a longitudinal direction and the second direction C 2  can be a transverse direction. Also, the third set of values associated with the biomechanical attributes can vary with a variation in the set of physical conditions. In some embodiments, the third set of values can be different from the first set of values associated with the biomechanical attributes under the same fixed set of physical conditions. 
     In some embodiments, the biomechanical attribute can include elasticity and a corresponding biomechanical parameter can be modulus of elasticity. In some embodiments, the biomechanical attribute can be viscoelasticity. In some embodiments, the biomechanical attribute can be viscohyperelasticity. In some embodiments, the biomechanical attribute can be anisotropicity. In various embodiments, the biomechanical attributes of the second portion  304  can be defined by defining one or more of shape, size, fabrication method or structure, profile, knit structure, pore size, material of fabrication, and the like. In some embodiments, for example, the congruence between the biomechanical behavior of the third bodily tissue and the second portion  304  can be achieved by varying the shape of the second portion  304 . For example, the trapezoidal shape of the second portion  304  can conform to shape of the posterior vaginal wall. 
     In some embodiments, the values of the biomechanical attributes of the second portion  304  can be defined by a fourth type of knit structure  324 . In some embodiments, the fourth type of knit structure  324  can be defined by a fourth type of knitting pattern  326 . In some embodiments, the fourth type of knit structure  324  can be defined by weaving the knit with a required and defined tension. For example, the posterior vaginal wall shows biomechanical behavior of anisotrophicity, with biasness (or being biased) toward more elongation along the direction C 1 , therefore, the fourth type of knitting pattern  326  can be selected to be more elastic along the direction C 2  as compared to the direction C 1 . 
     In some embodiments, the fourth type of knit structure  324  can be defined by a fourth type of pore construct  328 . In some embodiments, the fourth type of pore construct  328  is different from the first type of pore construct  220  and the second type of pore construct  236  of  FIG. 2 . The fourth type of pore construct  328  includes a plurality of pores  330 . The difference in pore construct for the first portion  302  and the second portion  304  can be achieved as described in  FIG. 2 . The fourth type of pore construct  328  can be configured to conform to biomechanical properties of the posterior vaginal wall. 
     In some embodiments, one or more of the biomechanical attributes can be defined by the third set of values associated with the biomechanical attributes for the second portion  304 . In an embodiment, the third set of values may be defined by a material used for fabricating the second portion  304 . For example, a viscoelastic medical grade polymer can be used for fabricating the second portion  304  thereby defining a desired value of viscoelasticity for the second portion  304 . In some embodiments, an anisotropic medical grade polymer can be used for achieving a desired value of anisotropicity. In some embodiments, the device is formed such that it has the desired value of anisotropicity is achieved. In some embodiments, a creep resistant medical grade polymer can be used for achieving a desired value of creep resistance. 
     The posterior vaginal wall can have high visco-hyper-elasticity. Therefore, the second portion  304  can have a high value of viscohyperelasticity under a fixed set of stress conditions. In some embodiments, the value of the biomechanical parameter can be different for the first direction C 1  and the second direction C 2  for the posterior vaginal wall. The value of the biomechanical parameter would be different for a set of high load conditions and a set of low load conditions for the posterior vaginal wall. For example, in some embodiments, the stiffness of the posterior vaginal wall at a low strain along the direction C 1  can range from 0.46-0.98 MegaPascal (MPa). In some embodiments, the stiffness of the posterior vaginal wall at a high strain along the direction C 1  can range from 2.49-9.08 MPa. In some embodiments, the stiffness of the posterior vaginal wall at the low strain along the direction C 2  can range from 1.14-1.46 MPa. In some embodiments, the stiffness of the posterior vaginal wall along the direction C 2  at the high strain can range from 2.39-3.83 MPa. These values indicate an anisotropic behavior and stiffness variation along different directions and different physical conditions for posterior vaginal wall. The stiffness behaviors of the posterior vaginal wall are explained in detail by  FIGS. 6A and 6B . Therefore, in some embodiments, the second portion  304  of the second flap  340  can be fabricated so as to define a set of values of the biomechanical parameter of stiffness that can conform to the values defining the biomechanical behavior of the posterior vaginal wall under similar load conditions. The second portion  304  can be fabricated such that the set of values of the biomechanical parameter can be different from the set of values for the same biomechanical parameter of the second portion  204  of the first flap  248 . 
     The second flap  340  further includes the transition region  306  as mentioned above. The transition region  306  defines a proximal portion  332  and a distal portion  334 . The proximal portion  332  can be coupled to or extend from the distal portion  322  of the second portion  304 . The distal portion  334  can be coupled to or extend from the proximal portion  312  of the first portion  302 . In some embodiments, the transition region  306  defines a fifth type of knit structure  336  that monolithically joins the first portion  302  and the second portion  304 . The fifth type of knit structure  336  defines a fifth pore construct  338 . In some embodiments, the third knit structure  244  may define a third type of pore construct  246 . 
     In some embodiments, the second flap  340  can be made out of a single strip of material. In some embodiments, the second flap  340  can be formed by suturing together the first portion  302  and the second portion  304 . In such cases, the transition region  306  includes sutures tying the first portion  302  and the second portion  304 . 
       FIG. 4  is a perspective view of a medical implant  400  including a plurality of flaps for placement over the first bodily tissue, the second bodily tissue and the third bodily tissue inside a patient&#39;s body. The plurality of flaps may include a first flap  402 , a second flap  404 , and a third flap  406 . The plurality of flaps can be joined together at a transition region  408  to form a Y-shaped implant as illustrated in the  FIG. 4 . In some embodiments, there may not be any transition regions such as the transition region  408  and the first, second, and third flaps can directly be coupled with the use of sutures or any other coupler. 
     The first flap  402  defines a proximal portion  420  and a distal portion  422 . The proximal portion  420  can be attached to or extend from the transition region  408  of the medical implant  400 . The distal portion  422  can be configured to be attached to the first bodily tissue as described with reference to  FIG. 2 . The first flap  402  can be configured to define the first set of values corresponding to the biomechanical parameters as explained in  FIG. 2  for emulating biomechanical behavior of first bodily tissue for example the sacrum, or tissue proximate the sacrum. 
     The second flap  404  defines a proximal portion  424  and a distal portion  426 . The proximal portion  424  can be attached to or extend from the transition region  408  of the medical implant  400 . The distal portion  426  can be configured to be attached to the second bodily tissue as described with reference to  FIG. 2 . The second flap  404  can be configured to define the second set of values corresponding to the biomechanical parameters as explained in  FIG. 2  for emulating biomechanical behavior of the second bodily tissue for example, the anterior vaginal wall. 
     The third flap  406  defines a proximal portion  428  and a distal portion  430 . The proximal portion  428  can be attached to or extend from the transition region  408  of the medical implant  400 . The distal portion  430  can be configured to be attached to the third bodily tissue as described with reference to  FIG. 3 . The third flap  406  can be configured to define the third set of values corresponding to the biomechanical parameters as explained in  FIG. 3  for emulating biomechanical behavior of third bodily tissue, for example, the posterior vaginal wall. 
     In some embodiments, the first flap  402 , the second flap  404  and third flap  406  can be fabricated independent of each other. The first flap  402 , the second flap  404  and the third flap  406  can be tied together with a suture  432  at the transition region  408  to form the medical implant  400 . In some embodiments, the three flaps  402 ,  404 , and  406  exhibit different biomechanical attributes owning to different biomechanical properties of anatomical locations that each of the three flaps  402 ,  404 , and  406  are configured to be attached to. 
     As mentioned above, the biomechanical properties of the posterior wall of vagina, the anterior wall of vagina and the sacrum or tissues proximate the sacrum inside a patient&#39;s body are different from each other; therefore in some embodiments the flaps of the medical implant  400  are fabricated with a pore construct and knit structure that can closely mimic biomechanical attributes of the anatomical locations inside the patient&#39;s body. For example, the first flap  402  can have a knit structure  410  similar to the first knit structure  216  of the first portion  202  of the first flap  248  from  FIG. 2  so as to be biomechanically congruent with the first bodily tissue. The second flap  404  can have a knit structure  412  similar to the second knit structure  232  of the second portion  204  of the first flap  248  from  FIG. 2  so as to be biomechanically congruent with the second bodily tissue. The third flap  406  can have a knit structure  414  similar to the fourth knit structure  324  of the second flap  340  from  FIG. 3  so as to be biomechanically congruent with the third bodily tissue. Upon placement, the first flap  402 , the second flap  404 , and the third flap  406  can act as three different arms that can be configured to support the pelvic organs like the anterior vaginal wall, the posterior vaginal wall and the sacrum by attaching the implant  400  at three distinct bodily locations. The three arms can be movable with respect to one another to conform to the shape of the target anatomical location of attachment inside the body. The three arms can take a shape such as linear/planar, curvilinear, curved, or any other shape. 
     In some embodiments, for example, the medical implant  400  can be formed by tying together the second portion  204  of the first flap  248 , the second portion  304  of the second flap  340  and the first portion  202  or  302  from either the first flap  348  or the second flap  340 . In such cases, the three portions mentioned above conform to the biomechanical attributes of the second bodily tissue, the third bodily tissue and the first bodily tissue respectively. 
       FIG. 5A  is a perspective view of a medical implant  500  formed as a tubular structure  502 . 
     The tubular structure  502  of the medical implant includes a first portion  504 , a second portion  506 , and a transition region  510 . The transition region  510  is formed from intersection of the first, and the second  504 , and  506  of the tubular structure  502  of the medical implant  500 . The medical implant  500  defines a proximal portion  512 , a distal portion  514  and a lumen  516  extending from the proximal portion  512  to the distal portion  214 . The medical implant  500  defines a length L 13  from the proximal portion  512  to the distal portion  514 . The medical implant includes the second portion  506  at the proximal portion  512  of the medical implant. The second portion can a first section  524  and a second section  508  and two slits  518 A and  518 B extending laterally along the length L 13  of the medical implant  500 . In some embodiments, the proximal portion  512  includes two slits extending laterally along the length L 13  and into the lumen  516  of the medical implant  500 . The slits  518 A and  518 B can configure first section  524  as apart from the second section  508  at a proximal end  534  of the medical implant  500 . The medical implant  500  can be configured so that each of the first portion  504 , the first section  524  and the second section  508  can define a set of biomechanical attributes, which can be congruent with the sacrum or tissues proximate the sacrum, the anterior vaginal wall and the posterior vaginal wall respectively. The congruency can be achieved by any of the methods described with reference to  FIGS. 2-3 . 
     The first portion  504  can define a knit structure  520  formed of a pore construct  522 . In some embodiments, the pore construct  522  can define a pore size so as to accommodate values of the biomechanical attributes the first bodily tissue. The first section  524  can define a knit structure  526  formed of a pore construct  528 . In some embodiments, the pore construct  528  can define a pore size so as to accommodate values of the biomechanical attributes the second bodily tissue. The second section  508  can define a knit structure  530  formed of a pore construct  532 . In some embodiments, the pore construct  532  can define a pore size so as to accommodate values of the biomechanical attributes the third bodily tissue. In some embodiments, the knit structure  520  of the first portion  504  is different from the knit structure  526  and the knit structure  530  of the first section  524  and the second section  508  of the second portion  506 . In some embodiments, the knit structure  526  of the first section  524  is different from the knit structure  530  of the second section  508 . 
     In some embodiments, the first portion  504  can be configured for attaching to the sacrum, the first section  524  to the anterior vaginal wall and the second section  508  to the posterior vaginal wall. In some embodiments, a value corresponding to a biomechanical parameter defining a biomechanical attribute of the first section  524  attaching to the anterior vaginal wall is different from a value of the same biomechanical parameter of the second section  508  attaching to the posterior vaginal wall. For example, the value of elasticity can be different for the first section  524  and the second section  508  under similar strain conditions. 
     In some embodiments, the medical implant  500  can be formed from a process of extrusion. The pore constructs  522 ,  528 , and  532 , in such cases can be the same. The medical implant can then be provided a heat treatment and different portions of the medical implant  500  can be heat set to different pore sizes. For example, the pore construct  522  can remain in a closed position without application of heat as illustrated in  FIG. 5B . The second portion  506  can be manually stretched to bring the medical implant  500  in an open position as illustrated in  FIG. 5C . This can increase a pore size of the pore constructs  528  and  532 . The pore construct  528  and the pore construct  532  can remain in an open position on application of heat over the first section  524  and the second section  508 . The first section  524  and the second section  508  may each be given heat treatment for setting different pore sizes so as to facilitate defining biomechanical attributes emulating biomechanical behavior of the anterior and posterior vaginal walls respectively. 
     In some embodiments, the medical implant  500  can be fabricated so that the first portion  504  includes the knit structure  216  and the pore construct  220  as described for the first flap  248 , the second portion  506  includes the knit structure  232  and the pore construct  236  as described for the first flap  248  and the third portion  508  includes the knit structure  324  and the pore construct  328  as described for the second flap  340 . 
       FIG. 5D  is a perspective view of a medical implant or medical device  900  according to an embodiment of the invention.  FIG. 5E  is a cross sectional view of the medical implant  900  taken along line Y-Y of  FIG. 5D .  FIG. 5F  is a top view of the medical implant  900 . 
     In some embodiments, the medical implant or medical device  900  is configured to be placed within a body of a patient and configured to provide support to a portion of the body of the patient, such as a vagina of the patient. In some embodiments, the medical device  900  is configured to be placed or implanted within a body of a patient via an abdominal incision. In other embodiments, the medical implant  900  may be placed or implanted within the body of the patient via another incision or opening such as a vaginal incision. 
     The medical implant  900  includes a first portion  904  and a second portion  906 . In some embodiments, the first portion  904  is configured to be attached to a sacrum of a patient or to a location proximate the sacrum of the patient. For example, an end portion  905  may be configured to be coupled or attached to the sacrum of the patient. The end portion  905  may be coupled or attached to the sacrum via any type of coupling methods, such as via a suture, an anchor, or an adhesive. Alternatively, the end portion  905  of the implant  900  may be passed through the coupling tissue to anchor or couple the medical implant  900  to or near the sacrum of the patient. In other embodiments, the first portion  904  is configured to be coupled or attached to another anchoring portion within the body of the patient. 
     The second portion  906  of the medical implant  900  includes a first flap  912  and a second flap  914 . In some embodiments, the first flap  912  may be coupled or attached to an anterior vaginal wall of the patient. For example, the first flap  912  may be sutured or coupled via another coupling mechanism, such as an anchor or an adhesive, to the anterior vaginal wall of the patient. In some embodiments, the second flap  914  may be coupled or attached to a posterior vaginal wall of the patient. For example, the second flap  914  may be sutured or coupled via another coupling mechanism, such as an anchor or an adhesive, to the posterior vaginal wall. In other embodiments, the first flap  912  and the second flap  914  may be coupled to other portions of the body of the patient. 
     As best illustrated in  FIG. 5E , the first portion  904  of the implant  900  has a tubular structure. Specifically, in the illustrated embodiment, the first portion  904  defines a lumen  902 . While the first portion  904  is shown as forming a circular or oval cross sectional shape, in other embodiments, the first portion  904  forms other shapes, such as a flattened oval shape. 
     The second portion  906  of the implant  900  is coupled to and extends from the first portion  904 . Specifically, the first flap  912  of the second portion  906  is coupled to and extends from the first portion  904 . In some embodiments, the first flap  912  is stitched to the first portion  904  (or coupled to the first portion  904  via suture  913 ). In other embodiments, the first flap  912  is coupled to the first portion  904  via another coupling mechanism, such as an adhesive or a coupler. The second flap  914  is coupled to and extends from the first portion  904 . In some embodiments, the second flap  914  is stitched to the first portion  904 . In other embodiments, the second flap  914  is coupled to the first portion  904  via another coupling mechanism, such as an adhesive or a coupler. 
     In some embodiments, the first portion  904  behaves differently in the body of the patient than the second portion  906 . For example, in some embodiments, the first portion  904  has a value corresponding to a biomechanical parameter defining a biomechanical attribute that differs from a value corresponding to a value of the biomechanical parameter defining the biomechanical attribute of the second portion  906 . For example, in some embodiments, the first portion  904  is stiffer or less flexible than the second portion  906 . In such embodiments, the second portion  906  is more flexible or more compliant than the first portion  904 . Specifically, the first flap  912  of the second flap  914  are more flexible or more compliant (and less stiff) than the first portion  904 . In some embodiments, first flap  912  may be more or less flexible than the second flap  914 . As the first flap  912  and the second flap  914  are flexible, in some embodiments, they may be configured to assume the flexibility or elasticity of the vaginal walls to which they are attached. As the first portion  904  is more stiff (less flexible), in some embodiments, the first portion  904  is configured to provide support to the body portions of the patient without flexing or stretching (or without a substantial amount of flexing or stretching). 
     In some embodiments, the first portion  904  is formed of a mesh material. The mesh material may be a woven or knitted mesh material. In some embodiments, the first portion  904  of the mesh material may be formed as a tubular structure. In other words, the tubular structure may be devoid of a seam. In other embodiments, the mesh material may be formed as a planar or substantially planar sheet and may be placed in a tubular form by coupling one side of the mesh material to another side of the mesh material. The sides or edges of the mesh material may be coupled together via stitching, a heat seal, an ultrasonic weld, or any other coupling mechanism. Sides or edges of mesh materials may be rough or have projecting fibers. In some embodiments, the sides or edges of the mesh material of the first portion  904  may be coupled together such that the rough portions of the sides or edges are not exposed (or on the outer surface of the first portion  904 . For example, as best illustrated in  FIG. 5E , the sides or edges may be coupled via a suture or a coupler  907  such that the edges are disposed towards or within the lumen  902  defined by the first portion  904 . In such embodiments, the first portion  904  may provide increased comfort to the patient as the bodily tissues of the patient may not be exposed to the rough surfaces  920  and  922  of the sides or edges of the mesh of the first portion  904 . For example, in some embodiments, without the rough surfaces of the edges being exposed, the first portion  904  is prevented from (or is less likely to) damaging bodily tissue or organs that contact the first portion  904 . 
     In other embodiments, the first portion  904  is formed of any other biocompatible material, such as a biocompatible synthetic material or a natural material. 
     In some embodiments, the first flap  912  and the second flap  914  are formed of a mesh material. The mesh material may be a woven or knitted mesh material. In some embodiments, the mesh material may be formed as a planar or substantially planar sheet. In other embodiments, the first flap  912  and the second flap  914  may be formed of any other biocompatible material, such as a biocompatible synthetic material or a natural material. 
     As best illustrated in  FIG. 5F , in the illustrated embodiment, the first portion  904  of the implant  900  has a width W 10  and the second portion  906  has a width W 20 . The width is defined as the size or length transverse to the longitudinal axis LA of the device. In the illustrated embodiment, the width W 10  of the first portion  904  is less than the width W 20  of the second portion  906 . For example, in some embodiments the width W 10  of the first portion  904  is between 1 and 13 centimeters and the width W 20  of the second portion  906  is between 1 and 13 centimeters. In some embodiments, the width of the first flap  912  is the same as the width of the second flap  914 . In other embodiments, the width W 10  of the first portion  904  is the same as the width W 20  of the second portion  906 . In some embodiments, the width W 10  of the first portion  904  is greater than the width W 20  of the second portion. 
     In some embodiments, a medical practitioner may modify or customize the device  900  prior to implantation into the body of the patient. For example, a medical practitioner may modify or customize the device  900  to best fit or to best serve the specific anatomy of the patient. In one embodiment, the first portion  904  of the device  900  may be cut, for example, along line Z 1 . In some embodiments, line Z 1  extends at an angle with respect to the axis defined by the lumen  902 . In some embodiments, line Z 1  extends parallel or substantially parallel to an axis defined by the lumen  902 . The medical practitioner may cut the device along line Z to effectively shorten the length of the first portion  904  that defines the lumen  902  (or in other words, to shorten the lumen  902 ). In some embodiments, a corresponding cut along line Z 2  may also be made. 
       FIG. 6A  is an exemplary graphical representation of relationship between stress applied on a vaginal tissue and resulting elongation in the vaginal tissue due to the applied stress. A medical implant can be fabricated to conform to the changes resulting in the vaginal tissue due to applied stress. The medical implant can be any of the medical implants  200 ,  300 ,  400 , and  500 . The vaginal tissue is generally viscoelastic or viscohyperelastic. The vaginal tissue can experience large deformation under small loads as shown. Therefore, in some embodiments, the medical implant is configured to experience varying levels of deformation under varying loads. The vaginal tissue stress-strain or load vs (or compared to) elongation relationship can follow a non-linear curve as illustrated. The curve has a first linear phase at low loads/stresses. At low levels of load, the strains or elongations are high defining a low stiffness attribute of the implant. The curve includes a second phase defined by a transition phase after an inflection point where it transitions from one linear phase to a third phase such that the curve is sharper in the third phase. The third phase defines a region of relatively lower elongation even under an application of relatively higher loads as compared to the first phase. That is to say that that after the load increases after a limit defined by the inflection point, there is lesser elongation with every unit change in load. This defines a property of high stiffness of the implant at higher loads. The unit change in elongation with every unit change in load decreases thereafter till it reaches a level that there is almost negligible elongation in the implant even at increased loads. The implant thus behaves as a stiff member. Therefore, the medical implant can be configured to define the attributes congruent with the stress-strain or load vs (or compared to) elongation relationship of the vaginal tissue. In some embodiments, the portion of the medical implant attaching to the anterior or posterior portion of the vagina can be so configured that it experiences large deformations over small loads until the inflection point is achieved. As the load is increased beyond the inflection point, the medical implant portion attached to the anterior vaginal wall or posterior vaginal wall starts exhibiting high stiffness and very less (negligible) deformation. 
     As mentioned with respect to  FIGS. 2 and 3  above, in some cases the vaginal wall may be anisotropic in nature; therefore, it experiences different elongations in different directions. For example, the vaginal wall in a traverse direction is generally more elastic than in a longitudinal direction. Therefore, it may be desirable to configure the medical implant to exhibit values of the biomechanical attributes defined to emulate the varying elongation behavior of the vaginal wall in different directions.  FIG. 6B  is a graphical representation of a comparison of an exemplary attribute, elongation, of the vaginal tissue in the transverse direction (or non-transverse direction) and the longitudinal direction. A shown, the elongation of the vaginal tissue in the transverse direction (or non-transverse direction) is much lesser than the elongation in the longitudinal direction. 
     Referring to the graphical representations of  FIGS. 6A-6B  that depict the characteristics and behavior of a vaginal tissue, the portions of the medical implant that are attached to vaginal tissues are configured to behave accordingly in order to emulate the behavior of the vaginal tissues such as the anterior and posterior vaginal walls. For example, in some embodiments, the portions of the implant that attach to the anterior vaginal wall can be configured to define different stiffness characteristics at different levels of loads on the implant portions. Similarly, the implant portions that attach to the posterior vaginal wall can be configured to define different characteristics in different directions such as the transverse direction and the longitudinal direction and for different load values. 
     In some embodiments, stiffness at the low strain or deformation phase can range from 0.431-4.15 MPa for the anterior vaginal wall in the longitudinal direction. In some embodiments, stiffness at the high strain or deformation phase can range from 5.15-17.28 MPa for the anterior vaginal wall in the longitudinal direction. In some embodiments, stiffness at a low strain or deformation phase can range from 0.46-0.98 MPa for the posterior vaginal wall in the longitudinal direction. In some embodiments, stiffness at a high strain or deformation phase can range from 2.49-9.08 MPa for the posterior vaginal wall in the longitudinal direction. In some embodiments, stiffness at the low strain or deformation phase can range from 0.385-0.415 MPa for the anterior vaginal wall in the traverse direction. In some embodiments, stiffness at the high strain or deformation phase can range from 0.370-0.61 MPa for the anterior vaginal wall in the traverse direction. In some embodiments, stiffness at the low strain or deformation phase can range from 1.14-1.46 MPa for the posterior vaginal wall in the traverse direction. In some embodiments, stiffness at the high strain or deformation phase can range from 2.39-3.83 MPa for the posterior vaginal wall in the traverse direction. The values of stiffness detailed here are a guide for vaginal tissues generally. The values of stiffness can be different depending on disease state, age, or any other influencing factor. Therefore, the implant can be made/designed accordingly to be configured for emulating the biomechanical behavior of the vaginal tissue in accordance with the desired characteristic behavior. 
       FIG. 7  is a perspective view of the medical implant  200 , including the first flap  248  and the second flap  340  of  FIG. 2  and  FIG. 3  respectively, placed inside a patient&#39;s body, in accordance with an embodiment of the invention. The body portions of the patient such as the vagina V, the anterior vaginal wall AVW, the posterior vaginal wall PVW, a urethra U, and the sacrum S are illustrated in  FIG. 7 .  FIG. 8  illustrates a method  800  for placing an implant in a patient&#39;s body. The method  800  is described below in conjunction with  FIGS. 2, 3, 4, 5, and 7-9 . The medical implant  200  including the first flap  248  and the second flap  340  is used as an exemplary embodiment to illustrate and discuss the method  800 . However, it must be appreciated that other implants such as the medical implant  400 , the medical implant  500 , and the medical implant  900  as discussed above can also be employed equally. 
     The method  800  includes inserting the first flap  248  of the medical implant  200  inside the body at step  802 . In some embodiments, the first flap  248  can be inserted inside the patient&#39;s body through a laparoscopic approach. In some embodiments, the method  800  includes creating an abdominal incision for delivering the medical implant inside the body laparoscopically. 
     The method  800  further includes attaching the first portion  202  of the medical implant  200  at the sacrum S inside the patient&#39;s body at step  803 . The first portion  202  can be configured to define the biomechanical attributes so as to emulate the biomechanical behavior of the sacrum S in a defined set of physical conditions. The biomechanical attributes can be defined by the first set of values of respective biomechanical parameters associated with the biomechanical attributes. 
     The method  800  further includes attaching the second portion  204  of the first flap  248  to the anterior vaginal wall AVW at step  804 . The anterior vaginal wall AVW is known to exhibit properties of viscoelasticity, anisotropy, and viscohyperelasticity. The second portion  204  can be configured to emulate the biomechanical behavior of the anterior vaginal wall AVW and define viscoelasticity, anisotropy, and viscohyperelasticity. The second portion  204  can define the biomechanical attributes that can be defined by the second set of values of respective biomechanical parameters associated with the biomechanical attributes as explained by way of  FIG. 2 . The first flap  248  is configured so that the first set of values is different from the second set of values. The difference in values can be attributed to the difference in the biomechanical behavior of the sacrum S and the anterior vaginal wall AVW. In some embodiments, the portion attaching to the anterior wall is formed monolithically with the first portion  202  and the transition region  206  as discussed above. It must be appreciated that any conventionally known or practiced methods or devices may be used for attaching the medical implant at any location inside the patient&#39;s body. 
     The method  800  further includes placing the second flap  340  of the medical implant  200  over the posterior vaginal wall PVW at step  806  as described below. 
     The first portion  302  can be configured to define the biomechanical attributes so as to emulate the biomechanical behavior of the sacrum S in a defined set of physical conditions. The biomechanical attributes can be defined by the first set of values of respective biomechanical parameters associated with the biomechanical attributes. The first set of values for the first portion  202  from the first flap  248  can be same as those for the first portion  302  from the second flap  340 . 
     The posterior vaginal wall PVW is known to exhibit properties of viscoelasticity, anisotropy, and viscohyperelasticity. The second portion  304  can be configured to emulate the biomechanical behavior of the posterior vaginal wall PVW and define viscoelasticity, anisotropy, and viscohyperelasticity. The second portion  304  can define the biomechanical attributes that can be defined by the third set of values of respective biomechanical parameters associated with the biomechanical attributes as explained by way of  FIG. 3 . The second portion  304  can be configured to define the biomechanical attributes congruent to the biomechanical behavior of the posterior vaginal wall. The medical implant  200  can be fabricated so that second flap  340  is configured to have the third set of values corresponding to the biomechanical attributes to be different from the second set of values corresponding to the first flap  248 . Therefore, the second portion  204  of the first flap  248  used for attaching to the anterior vaginal wall AVW defines a different set of values corresponding to a biomechanical parameter than the set of values corresponding to the same biomechanical parameter for the second portion  302  of the second flap  340  attaching to the posterior vaginal wall. In this way, the properties of the first flap  248  and the second flap  340  are different and congruent with respect to the portions the first flap  248  and the second flap  340  are attached to. In some embodiments, the portion attaching to the posterior vaginal wall PVW is formed monolithically with the first portion  302  and the transition region  306  as discussed above. It must be appreciated that any conventionally known or practiced methods or devices may be used for attaching the medical implant at any location inside the patient&#39;s body. In some embodiments, the tow flaps can be independent from each other and may collectively enable the medical implant  200  in emulating biomechanical behavior of the anterior vaginal wall AVW, posterior vaginal wall PVW and the sacrum S inside a patient&#39;s body.
