Title: Vaginal laxity and uterine prolapse device

Description:
BACKGROUND 
     Some medical procedures result in looseness/loss of tightness in the vaginal and/or pelvic muscles. For example, after child birth, many women experience looseness in the vaginal and/or pelvic floor muscles that can result in uncontrolled urine discharge (for example as a result of sneezing), loss of feeling, and/or loss of sexual fulfillment. In addition, many women experience anxiety regarding looseness after child birth. Many exercises have been developed for tightening of the pelvic floor and/or vaginal muscles, such as, for example, Kegel exercises. These exercises require prolonged and frequent use in order to produce noticeable results.

     DETAILED DESCRIPTION 
     The description of the preferred embodiments is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description of this invention. The drawing figures are not necessarily to scale and certain features of the invention may be shown exaggerated in scale or in somewhat schematic form in the interest of clarity and conciseness. In this description, relative terms such as “horizontal,” “vertical,” “up,” “down,” “top,” “bottom,” as well as derivatives thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing figure under discussion. These relative terms are for convenience of description and normally are not intended to require a particular orientation. Terms including “inwardly” versus “outwardly,” “longitudinal” versus “lateral,” “proximal” versus “distal” and the like are to be interpreted relative to one another or relative to an axis of elongation, or an axis or center of rotation, as appropriate. Terms concerning attachments, coupling and the like, such as “connected” and “interconnected,” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both moveable or rigid attachments or relationships, unless expressly described otherwise. The term “operatively coupled” is such an attachment, coupling, or connection that allows the pertinent structures to operate as intended by virtue of that relationship. In the claims, means-plus-function clauses, if used, are intended to cover structures described, suggested, or rendered obvious by the written description or drawings for performing the recited function, including not only structure equivalents but also equivalent structures. 
     In various embodiments, a vaginal laxity/uterine prolapse system is disclosed. The vaginal laxity/uterine prolapse system generally comprises a vaginal laxity/uterine prolapse device and a suction device. The vaginal laxity/uterine prolapse device generally includes a shaft sized and configured for insertion into a patient&#39;s vagina. The shaft includes a plurality of suction ports. The shaft is coupled to a suction device configured to generate suction in the vagina through the plurality of suction ports. The suction within the vagina causes both immediate and chronic decrease in the compliance of the vagina, increasing the frictional resistance to penile penetration (e.g., “tightness”) to treat vaginal laxity and conversely increasing the frictional resistance to retrograde displacement of the uterus to decrease the frequency and severity of vaginal prolapse. In some embodiments, repeated use of the vaginal laxity/uterine prolapse device results in permanent tightening of the vagina and/or a vaginal opening. 
       FIG. 1  illustrates one embodiment of a vaginal laxity/uterine prolapse system  100 . The vaginal laxity/uterine prolapse system  100  includes a vaginal laxity/uterine prolapse device  102 . The vaginal laxity/uterine prolapse device  102  comprises a shaft  104  extending longitudinally along a shaft axis. The shaft  104  is sized and configured for insertion into a body cavity of a patient, such as, for example, a vagina. In some embodiments, the shaft  104  comprises a rigid shaft. The shaft  104  is configured to extend from a vaginal opening a predetermined distance into the vagina. In some embodiments, the shaft  104  has a length approximately equal to the average distance from the labial folds to the cervix, such as, for example, about 7 inches. In some embodiments, the length of the shaft  104  is adjustable. 
     In some embodiments, the shaft  104  comprises a profile sized and configured to partially or completely seal the vaginal opening after insertion. For example, the shaft  104  comprises a proximal section  112  having a diameter greater than the diameter of the remainder of the shaft  104 . The increased diameter of the proximal section  112  is larger than the unexpanded diameter of the vaginal opening when the shaft  104  is inserted into the user&#39;s vagina. The proximal section  112  contacts the wall of the vaginal opening and seals the vaginal opening. In some embodiments, the shaft  104  comprises a distal section  114  configured to allow easy insertion of the vaginal laxity/uterine prolapse device  102  into the vaginal opening. For example, in some embodiments, the distal section  114  of the shaft  104  has a maximum diameter that is substantially less than an average penile diameter, such as, for example, a ¼″. 
     The shaft  104  is coupled to a handle (or base) section  106 . The handle  106  is sized and configured to allow a user to grip the vaginal laxity/uterine prolapse device  102  during insertion/removal. The handle  106  is configured to remain outside of a user. In some embodiments, the handle  106  comprises one or more vent slots  107  configured to allow air flow into/out of the shaft  104  (described in more detail below.) In some embodiments, a sealing cup (or suction cup)  108  is located between the shaft  104  and the handle  106 . The sealing cup  108  is located proximally of the proximal section  112  of the shaft  104 . The sealing cup  108  is sized and configured to contact and seal the vaginal opening. In some embodiments, the sealing cup  108  is sized and configured to fit completely over the vaginal opening, the labial lips, and/or the pelvic area of a user. The sealing cup  108  fits over at least the vaginal opening and seals the outer surface of the vaginal opening. In some embodiments, the sealing cup  108  is positioned such that the sealing cup  108  covers the vaginal opening when the proximal section  112  of the shaft  104  is in contact with the walls of the vaginal opening. In some embodiments, the sealing cup  108  may be similar to a contraceptive diaphragm. The sealing cup  108  can comprise a concave, convex, and/or flat contact profile and may comprise any suitable material, such as, for example, plastic and/or rubber. 
     In some embodiments, the shaft  104  includes a plurality of suction openings  110  distributed over the length of the shaft  104 . The plurality of suction openings  110  each include one or more channels or holes formed through the shaft  104 . The shaft  104  defines an inner channel (not shown) in fluid communication with the one or more channels of the suction openings  110 . In some embodiments, the plurality of suction openings  110  are located within one or more suction tracts  111 . The suction openings  110  allow air flow between the vagina and a volume of air outside of the patient. Air flow from within the vagina to the outer volume generates a vacuum within the vagina, causing increased vaginal blood flow and/or muscle contractions. The increased vaginal blood flow generates an edema and/or hypertrophy of the vaginal walls. 
     The plurality of suction openings  110  may be disposed in any suitable pattern, such as, for example, a symmetrical pattern, a non-symmetrical pattern, a random pattern, and/or any other suitable pattern. The plurality of suction openings  110  may be located on only a portion of the shaft  104  and/or over the entire length of the shaft. For example, in various embodiments, the plurality of suction openings are located only on the distal section  114 , only on the proximal section  112 , and/or on any other suitable section of the shaft  104 . In some embodiments, the plurality of suction openings  110  comprise different diameters. The diameter of a specific suction opening  110  may depend on, for example, the location of the suction opening  110  on the shaft  104 . For example, in some embodiments, the diameters of the suction openings  110  may change uniformly over the length of the shaft  104 . 
     The plurality of suction openings  110  are in fluid communication with an internal channel defined by the shaft  104 . For example, in some embodiments, the shaft  104  is hollow and the entire inner volume comprises an internal channel. In other embodiments, the shaft  104  is semi-solid and has an internal channel formed therein. The internal channel is coupled to the handle section  106 . In some embodiments, suction is generated by a suction device  116 . The suction device may be located within the handle section  106  and/or coupled to the prolapse device  102  by a suction tube  108  (as shown in  FIG. 1 ). In the illustrated embodiment, a hand pump  116  is coupled to the handle section  106  by a suction tube  118 . Actuation of the hand pump  116  causes air to flow from the vagina, through the plurality of suction openings  110  and the inner channel, and out of the one or more vent slots  107  formed in the handle  106 . The flow of air out of the vaginal laxity/uterine prolapse device  102  generates suction within the vagina to draw the vaginal walls towards the shaft  104  of the vaginal laxity/uterine prolapse device  102 . 
     The negative pressure within the vagina increases vaginal blood flow. The increased blood flow causes edema of the vaginal walls and/or hypertrophy of the vaginal wall muscle. In some embodiments, repeated and/or prolonged use, such as, for example, as part of a treatment regimen, inhibits vaginal laxity/uterine prolapse, causes permanent hypertrophy of the vaginal walls/muscles, and/or increases sexual pleasure of the patient as a result of the increased blood flow, muscle thickness, and reduced size of the vagina. In some embodiments, the vaginal laxity/uterine prolapse system  100  comprises a novelty/periodic use device configured to temporarily increase blood flow, vaginal tightness, and sensitivity to increase sexual enjoyment for a user and/or a partner. In other embodiments, the vaginal laxity/uterine prolapse system  100  comprises a medical device configured for medical treatment of vaginal laxity/uterine prolapse and/or to permanently increase vaginal tightness and/or hypertrophy, for example, after child birth. 
     In some embodiments, the vaginal laxity/uterine prolapse system  100  is used in conjunction with one or more rehabilitative exercises. For example, in some embodiments, the vaginal laxity/uterine prolapse system  100  is combined with pelvic floor exercises, such as, for example kegel exercises, to increase vaginal tightness and/or blood flow to the vaginal area. In some embodiments, the vaginal laxity/uterine prolapse system  100  is configured to be used simultaneously with the rehabilitative exercises, e.g., kegel exercises may be performed during application of suction by the vaginal laxity/uterine prolapse device  102 . In other embodiments, the vaginal laxity/uterine prolapse system  100  is used in conjunction with the rehabilitative exercises, e.g., the vaginal laxity/uterine prolapse device may be used between kegel exercise sessions. 
       FIG. 2  illustrates one embodiment of a vaginal laxity/uterine prolapse system  200  including a vaginal laxity/uterine prolapse device  202  having a suction device  216  in the handle  206 .

       FIGS. 13A-13E  illustrate one embodiment of a vaginal laxity/uterine prolapse device  1102  coupled to a manual hand pump  1116 . The vaginal laxity/uterine prolapse device  1102  is similar to the vaginal laxity/uterine prolapse devices described above. The vaginal laxity/uterine prolapse device  1102  is coupled to the manual hand pump  1116  by a suction cord  1118 . The manual hand pump  1116  is shown with a side wall removed. In operation, a user actuates the handle  1144  of the manual hand pump  1116  to generate negative pressure through the plurality of suction openings  1140  formed in the shaft  1104  of the vaginal laxity/uterine prolapse device  1102 .  FIGS. 13C-13E  illustrate operation of the hand pump  1116 .  FIG. 13C  illustrates the hand pump  1116  in an initial position. The vaginal laxity/uterine prolapse device  1102  is inserted into the vagina with the hand pump  1116  in the initial position. When the shaft  1104  of the vaginal laxity/uterine prolapse device  1102  is inserted, the vagina is sealed by the sealing cup  1108  and the internal protective cup  1120 . A user and/or a clinician actuates the hand pump  1116  to generate negative pressure within the vagina. The handle  1144  of the hand pump  1116  is drawn proximally from an initial position  1144   a  (shown in  FIG. 13C ) to a proximal-most position  1144 B (shown in  FIG. 13D ). The handle  1144  is coupled to a seal  1146  located within the cavity  1142  by a shaft  1148 . 
     Proximal movement of the seal  1146  (as a result of proximal movement of the handle  1144 ) causes the seal  1146  to move within the cavity  1142 , generating a vacuum space  1150  within the body  1140 . The vacuum space  1150  has at least a partial vacuum that causes air  1152  to flow from within the vagina, through the plurality of suction holes  1110 , the internal channel, the suction tube  1118  and into the vacuum space  1150 , generating a negative pressure within the vagina. The negative pressure generated within the vagina is proportional to the size of the vacuum space  1150  available within the body  1142  of the hand pump  1116 . After reaching a proximal-most position (user selected and/or mechanically limited), the handle  1144  of the hand pump  1116  may be driven distally to reverse the flow of air  1154  into the vaginal cavity and reduce the negative pressure generated therein.  FIG. 13E  illustrates the handle  1144   c  in a partially distal position corresponding to the release of negative pressure within the vaginal cavity. The hand pump  1116  cycle may be repeated to generate and release negative pressure within the vaginal cavity any number of times, such as, for example, until a specific level of blood flow, a specific time period, and/or until any other threshold parameter is met. In some embodiments, one or more vent openings are formed in the housing of the hand pump  1116  to allow air to be expelled from and/or enter into the cavity  1142  during actuation of the handle  1144 . 
       FIG. 14A  illustrates one embodiment of a vaginal laxity/uterine prolapse system  1200  including the vaginal laxity/uterine prolapse device  1102  coupled to a hand suction pump  1216 .

       FIGS. 14B and 14C  illustrate operation of the hand pump  1216 . The lever  1242  of the hand pump  1216  is illustrated in an initial position  1242   a  in  FIG. 14B . The lever  1242   a  is in the initial position during insertion of the vaginal laxity/uterine prolapse device  1102  into the vaginal opening. After insertion of the shaft  1104  into the vagina, the lever  1242  is actuated from the first position  1242   a  to the second position  1242   b . Actuation of the lever  1242  towards the handle  1240  generates negative pressure within the vagina through air flow  1246  out of the vaginal laxity/uterine prolapse device  1102 . For example, in some embodiments, the hand pump  1216  shares a similar internal construction to the hand pump  1116 . Releasing and/or actuating the lever  1242  away from the handle  1240  releases the negative pressure within the vagina. In other embodiments, repeated actuation of the lever  1242  increases the negative pressure within the vagina.  FIG. 14D  illustrates the vaginal laxity/uterine prolapse device  1102  applying suction caused by the flow of air  1246 .

For example, in one embodiment, the pressure measuring device  1600  is inserted through the vaginal opening immediately following a treatment session utilizing a vaginal laxity/uterine prolapse device. The pressure measure device  1600  provides a pressure reading indicative of the increased vaginal blood flow developed by the vaginal laxity/uterine prolapse device. The pressure measuring device  1600  can be used to indicate whether a desired level of blood flow and/or muscle tightness has been achieved. 
     In some embodiments, the pressure measuring device  1600  and/or a vaginal laxity/uterine prolapse device includes a wireless communication module (not shown). The wireless communication module is configured to communicate with a computing device, such as, for example, a smartphone. The wireless communication module provides a signal indicative of the pressure achieved at a given internal diameter of the vagina. The computing device is configured to provide a record of pressure achieved at a given internal diameter, e.g., “tightness,” to a user. In some embodiments, tightness is proportional to the positive pressure required to achieve a given vaginal internal diameter, for example, vaginal tone (“tightness”) pressure/(internal diameter). In some embodiments, the wireless communication module is configured to receive inputs from the computing device, such as, for example, suction control signals. The suction control signals may be received in response to user input and/or pre-programmed response algorithms. 
     In other embodiments, the pressure measuring device  1600  is used to determine the long term effects of the vaginal laxity/uterine prolapse device. For example, the pressure measuring device  1600  may be used in between treatment sessions using a vaginal laxity/uterine prolapse device to measure the gradual increase of pressure within the vagina caused by increased muscle size and hypertrophy of the vaginal/pelvic region. The pressure measuring device  1600  may be used to measure progress, adjust a treatment regimen, and/or to otherwise monitor the use of the vaginal laxity/uterine prolapse device over an extended period. 
       FIG. 20  is a flowchart illustrating one embodiment of a method  1700  for generating edema and/or hypertrophy of a vaginal wall. The method and associated devices provides both immediate (e.g., within minutes) and chronic (e.g., over days to weeks of repetitive application) decrease in the compliance of the vagina, increasing the frictional resistance to penile penetration (i.e., “tightness”) to treat vaginal laxity and conversely increasing the frictional resistance to retrograde displacement of the uterus to decrease the frequency and severity of uterine prolapse. The method  1700  includes a first step  1702  of inserting a vaginal laxity/uterine prolapse device through a vaginal opening of a patient/user. The vaginal laxity/uterine prolapse device includes a shaft sized and configured for insertion into the vagina through the vaginal opening. The shaft has a plurality of suction openings formed through the shaft and coupled to an internal channel defined by the shaft. The vaginal laxity/uterine prolapse device may be, for example, any one of the vaginal laxity/uterine prolapse devices described in conjunction with  FIGS. 1-18C . 
     In a second step  1704  of the method  1700 , the vagina is sealed. The vagina may be sealed by, for example, a sealing cup located at a proximal end of the shaft and/or a sealing profile defined by the proximal end of the shaft. The sealing cup and/or the sealing profile are sized and configured to seal the vaginal opening. In an optional third step  1706 , a cervix is sealed by an internal protective cup located at a distal end of the shaft. The internal protective cup is sized and configured to fit at least partially over the cervix and to protect the cervix and/or uterus from negative pressure generated within the vagina. 
     In a fourth step  1708 , negative pressure is generated inside of the vagina to cause edema and/or hypertrophy of the vaginal walls. The negative pressure is generated by a suction device located externally to the vagina. In some embodiments, the suction device is coupled to the shaft of the vaginal laxity/uterine prolapse device by a suction tube. The suction device generates negative pressure through the plurality of suction openings formed on the shaft. The negative pressure causes increased blood flow to the vaginal walls and edema and/or hypertrophy of the vaginal walls. 
     In an optional fifth step  1710 , a user performs one or more pelvic floor exercises simultaneously and/or alternatively with the generation of negative pressure. For example, in some embodiments, a user may perform pelvic floor exercises such as kegel exercises simultaneously with the generation of suction by the vaginal laxity/uterine prolapse device. In other embodiments, the user may alternate the suction and the pelvic floor exercises.
