## Background
This application is a Continuation Application of U.S. patent application Ser. No. 11/537,891, filed Oct. 2, 2006, which claims the benefit of and priority to U.S. Provisional Application No. 60/724,332, filed Oct. 5, 2005, with each of the above-referenced Applications incorporated herein by reference in their entirety.


FIELD OF THE INVENTION
The invention relates generally to treatments for providing anatomical support within the human pelvis. More particularly, the invention relates to devices and surgical techniques for treating incontinence through use of an anatomical support.
BACKGROUND OF THE INVENTION
There are various surgical techniques that use mesh or other devices to support portions of a patient's body such as bladder or uterus, for example those described in U.S. Pat. Nos. 6,911,003 and 6,884,212, which are hereby incorporated by reference. While it is possible to make a relatively large incision to provide the surgeon with direct access to the area in which the mesh support structure is being placed, this technique is undesirable because it not only increases the potential of complications but also increases the time for the patient to recover from the surgery.
As such, it is desirable to make relatively small incisions in the patient and then feed the mesh support structure to desired locations using needles or other devices. There are several challenges associated with using needles to position the mesh support structure. The most significant challenge relates to attaching the mesh support structure to the needle so that the mesh support structure can be readily moved inside of the patient.
One technique used by the assignee of the present application to attach insertion needles to mesh support structures is through a snapping connection. Such a connection requires a relatively large force (at least 10 pounds) to disconnect the insertion needle from the mesh support structure to ensure that the mesh support structure does not inadvertently detach from the insertion needle during the insertion of the mesh support structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The invention is directed to several devices and techniques for use in positioning mesh within a patient (male or female) that are discussed in more detail below.
A conventional technique used for treatment of vaginal wall prolapse is with a mesh support structure having four legs extending therefrom. To reduce the risks of contamination, this surgical procedure is performed using a kit that not only includes the mesh support structure but also four insertion needles that are used for positioning the mesh support structure within the patient. Similar kits have also been used to treat urinary stress incontinence.
To substantially reduce the potential of the insertion needle detaching from the mesh as the mesh is positioned in the patient, a prior technique for attaching the insertion needle to the mesh utilizes a snapping or locking mechanism. The friction fit mechanism typically requires a relatively large lineal force of greater than 10 pounds to detach the insertion needle from the mesh support structure.
Because this embodiment of the invention enables the needle to be readily detached from the connector, this embodiment enables a mesh support structure having four legs to be inserted using two insertion needles. The insertion needles used in this embodiment may be identified as right and left.
The insertion needles each include a connector that enables the insertion needles to be readily detached from the mesh support structure. Each of the insertion needles is used with a connector that allows for quick detachment from the mesh support structure either through a quick detachment geometry built into the insertion needle or the connector, or through the use of a tool that aides in the quick removal of the connector from the insertion needle.
In one configuration of the needle, the needle 100 includes at least one J-shaped slot 102 formed therein, as illustrated in FIGS. 1-3. The connector 104 includes an inwardly directed extension 106 that extends from a wall of the aperture 108 through which the needle 100 is inserted, as illustrated in FIG. 4. The inwardly directed extension 106 has a width that is slightly smaller than a width of the J-shaped slot 102.
When connecting the connector 104 to the insertion needle 100, the connector 104 is moved towards the insertion needle 100, as illustrated by arrow 110 in FIG. 5, until the insertion needle 100 extends into the connector 104. As the insertion needle 100 is inserted into the connector 104, the inwardly directed extension 106 slides in the J-shaped slot 102 until the inwardly directed extension 106 contacts the bottom of the J-shaped slot 102. At that time, the connector 104 is rotated with respect to the insertion needle 100, as illustrated by arrow 112 in FIG. 6. The connector 104 is then pulled away from the insertion needle 100, as illustrated by arrow 114 in FIG. 7.
The connector 104 is thereby attached to the insertion needle 100 such that lineal pulling and pushing of the insertion needle 100 enables the connector 104 and the attached portion of the mesh support structure to be pulled through the patient. Once the mesh support structure is pulled to a desired location, the attachment process set forth above is reversed to detach the connector 104 from the insertion needle 100.
In another configuration of the connector, a tool 120, illustrated in FIG. 8, is provided to detach the connector 122 from the insertion needle 124. At least one leg 126 is provided on an inner surface of the connector 122, as illustrated in FIG. 9. As the insertion needle 124 is inserted into the connector 122, the leg 126 engages a ridge 128 extending from the insertion needle 124 and thereby retains the connector 122 on the insertion needle 124. The legs 126 may be positioned on opposite sides of the connector 122 such that pushing opposite legs 126 towards each other enables the connector 122 to be released from the insertion needle 124.
Each leg 126 may be positioned proximate an opening 130 that extends through a wall of the connector 122. Each opening 130 is adapted to receive a tab 132 on a pliers-like tool 120. When the tab 132 engages the leg 126, the connector 122 may be removed from the needle 124.
Using this system, the right and left insertion needles are inserted into the patient using conventionally known techniques. The right and left insertion needles are then connected to two of the legs extending from the mesh support structure and the insertion needles are withdrawn from the patient to pull each of the legs through the associated obturator. Each of the connectors is then disengaged to separate the insertion needles from the mesh support structure, the process is then repeated to insert the other two legs into the desired location in the patient.
As an alternative to using a one-piece connector that is discussed above, it is also possible to use a two-piece connector 140, as illustrated in FIG. 10. In the two piece connector 140, a proximal connector portion 142 is attached to the insertion needle 144 and a distal connector portion 146 is attached to the mesh support structure 148. The proximal connector portion 142 and the distal connector portion 144 engage each other to attach the insertion needle to the connector 140 such as by using one of the connection methods described herein.
Another configuration for removably attaching the connector to the needle includes an insertion needle 150 with a reduced diameter section 152 that is adjacent to but offset from a tip 154 of the insertion needle 150, as illustrated in FIG. 11. The reduced diameter section 152 may have a length of about 0.75 inches. The connector 156 includes at least one inwardly directed tab 158 that engages a lip 160 where the reduced diameter section 152 and the tip 154 intersect to retain the connector 156 on the insertion needle 150.
When it is desired to remove the connector 156 from the insertion needle 150, a C-shaped collar 162 is placed over the reduced diameter section 152, as illustrated in FIG. 12. The collar 162 is formed with a length based upon the length of the reduced diameter section 152 and the distance to the tab 158 from the front of the connector 156.
The collar 162 is then urged towards the tip 154, as illustrated in FIG. 13. The collar 162 thereby contacts the at least one inwardly directed tab 158 and urges the inwardly directed tab 158 outward. When this occurs, the inwardly directed tab 158 no longer engages the lip 160, which allows the connector 156 to be removed from the insertion needle 150. The collar 162 may be removed from the reduced diameter section 152 and the insertion needle 150 may be reused. Alternatively, the collar 162 may be permanently left on the insertion needle 150.
Alternatively, a channel 170 may be formed in the insertion needle 172, as illustrated in FIG. 14. The channel 170 would receive an arm 174 or other device that extends to proximate the lip 160. The arm 174 may be pivoted to urge the inwardly directed tab outward.
In yet another configuration of the removable connector, a pump action mechanism is provided to detach the connector 180 from the insertion needle 182, as illustrated in FIGS. 15-17. Using this mechanism, the collar 184 is formed with a length that may be less than a length of the reduced diameter region 186. This configuration enables the collar 184 to slide with respect to the insertion needle 182.
When the connector 180 is initially attached to the insertion needle 182, the connector arms 188 engage a lip 190 where the tip 192 and the reduced diameter region 186 intersect. When it is desired to remove the connector 180 from the insertion needle 182, the connector 180 is urged away from the distal end of the insertion needle 182, as illustrated in FIG. 15.
Sliding of the collar 184 away from the distal end of the insertion needle 182 is limited by a stop 194 provided at a proximal end of the reduced diameter region 186. This movement causes the connector arms 188 to be positioned over the collar 184, as illustrated in FIG. 15.
Thereafter, the connector 180 is moved away from the insertion needle 182. The lip 190 limits movement of the collar 184, as illustrated in FIG. 16. The continued pulling of the connector 180 away from the insertion needle 182 causes the connector arms 188 to move past the lip 190 to release the connector 180 from the insertion needle 182, as illustrated in FIG. 17.
The collar 184 may include a ridge 196 or indent on an outer surface thereof, as illustrated in FIGS. 18-20, to assist in the connector arms 188 retaining the collar 184 during movement.
A lip 200 may also include an angled surface 202 that forms a pocket, as illustrated in FIGS. 21-22. The angled surface 202 may substantially correspond with an angled surface 204 on a distal end 206 of the collar 208. This configuration of the insertion needle 210 and collar 208 enhances the ability to provide a smooth transition between the collar 208 and the lip 200 even if they are not in exact alignment.
Yet another configuration of the collar 212 includes a lip 214 proximate a distal end 216 thereof, as illustrated in FIGS. 23-24. The lip 214 extends over a portion of the tip 218 when the connector is being removed from the insertion needle 220 to enhance the ability to remove the connector from the insertion needle 220.
Another configuration of the connector 230 has at least one slit 232 in the distal end 234 thereof, as illustrated in FIG. 25. Once the insertion needle (not shown) is inserted into the connector 230, legs (not shown) engage a lip near the tip of the needle to retain the connector 230 on the insertion needle in response to lineal movement of the needle towards and away from the connector 230. Alternatively, it is possible to form the connector 230 from a flexible material that provides a performance that is similar to the slit 232
When it is desired to remove the connector 230 from the insertion needle, the connector 230 is pivoted with respect to the insertion needle, as indicated by arrow 236. At least one slit 232 enables sides 238 of the connector 230 to be urged apart from each other, which thereby releases the connector 230 from the insertion needle.
Concerns when feeding mesh through a patient are minimizing a profile of the region proximate the interconnection between the needle and the mesh and providing a smooth outer surface.
Instead of feeding the mesh assembly through a hole in the side of the connector, the above concerns may be addressed by attaching the mesh assembly to a proximal end of the connector.
As an initial step in attaching the mesh assembly 250 to the connector 252, an outer sheath 254 on the mesh assembly 250 is rolled so that a distal end 256 of the sheath 254 is generally tubular, as illustrated in FIG. 26. The distal end 256 of the sheath 254 is extended through a collar 258 and a barbed adaptor 260 is inserted into the sheath 254.
The collar 258 is moved over the barbed adaptor 260 to retain the adaptor 260 in a fixed position with respect to the mesh assembly 250. The adaptor 260 may be then secured to the connector 252 using a snap feature 262.
An alternative technique for attaching a mesh assembly 270 to a connector 272 includes an aperture 274 in the connector 272 that is oriented substantially transverse to a central axis 276 of the connector 272, as illustrated in FIG. 27. A corresponding aperture 278 would be formed in the mesh assembly 270.
The mesh assembly 270 is inserted into the proximal end of the connector 272 until the aperture 274 in the connector 272 is generally aligned with the aperture 278 in the mesh assembly 270. A pin 280 is then inserted through the connector and mesh assembly apertures 274, 278 to retain the connector 272 and mesh assembly 270 in a fixed position with respect to each other.
Another technique for attaching a mesh assembly 290 to a connector 292 would be through the use of an adaptor 294, as illustrated in FIG. 28. A proximal end 296 of the adaptor 294 has an eyelet 298 extending therethrough that is adapted to receive the mesh assembly 290.
A distal end 300 of the adapter 294 is then attached to the connector 292 such as through welding or a snap feature. Alternatively, the distal end 300 of the adapter 294 may have a threaded outer surface. The threaded outer surface would engage a threaded inner surface in the connector 292 to removably attach the mesh assembly 290 to the connector 292.
As an alternative to providing at least one leg on the connector for attaching the connector to the needle, the connector 320 may include a C-shaped connector 322 that extends inwardly from a wall thereof, as illustrated in FIG. 29. To compensate for the force applied to the C-shaped connector 322 as the connector 320 is attached to an insertion needle 326 or as the assembly is pulled through the tissue, one or more ribs 324 may extend from the C-shaped connector 322 to the wall of the connector 320, as illustrated in FIG. 30.
As the insertion needle 326 is inserted into the C-shaped connector 322, the walls of the C-shaped connector 322 are urged apart from each other to allow the needle 326 to pass therethrough. Once the tip of the needle 326 passes the C-shaped connector 322, the C-shaped connector 322 engages the lip 328 and thereby prevents the connector 320 from being removed from the insertion needle 326.
Another technique to reduce the potential of the C-shaped connector 322 being damaged during insertion of the needle 326 into the connector 320 is through a support shelf 330 that extends from an opposite wall of the connector 320, as illustrated in FIG. 31. Forces generated during the insertion of the needle 326 into the connector 320 would thereby be distributed over both the C-shaped connector 322 and the support shelf 330.
The wall of the connector 320 above an open end of the C-shaped connector 322 may have an aperture 332 formed therein, as illustrated in FIGS. 32-33. When it is desired to separate the connector 320 from the insertion needle 326, a tool (not shown) having a thin blade such as a screwdriver is inserted into the aperture 332 to cause the legs of the C-shaped connector 322 to more apart from each other to thereby release the needle 326.
To further enhance the ability to move apart the arms of the C-shaped connector 322, an extension 334 may be provided on the end of the C-shaped connector 322 to increase the surface areas that the tool contacts, as illustrated in FIGS. 33-34.
As an alternate to the embodiment discussed with respect to FIGS. 29-34, it is also possible to form a locking mechanism 340 to be removed using a squeezing motion. In one configuration, the locking mechanism 340 may have a generally circular shape having an opening 342 at one side thereof, as illustrated in FIGS. 35-36.
To facilitate attaching and detaching the locking mechanism 340, a first extension 344 and a second extension 346 extend from opposite ends of the locking mechanism 340. An end of the first extension 344 extends beyond an end of the second extension 346.
Depending upon the material from which the locking mechanism 340 is formed, it may be necessary to increase the flexibility of the first and second extensions 344, 346 by providing a slot 350 therebetween, as illustrated in FIG. 37. A person of skill in the art will appreciate that the deeper the slot 350, the more flexibility that is imparted to the first and second extensions 344, 346.
The first extension 344 and the second extension 346 may each have a tab 352 extending outwardly therefrom proximate an end thereof. Since the first extension 344 is offset from the second extension 346, urging the tabs 352 towards each other causes a diameter of the locking mechanism 340 to increase and thereby allows the locking mechanism 340 to release the needle (not shown). When removing the locking mechanism 340, it may be necessary to urge the tabs 352 pas
Compared to conventional tabs that do not overlap, moving the tabs 352 the same distance requires a smaller net space, which translates into a smaller window in the connector sidewall. The net space is smaller because the travel of the tabs overlap each other, as illustrated in FIGS. 38-40.
In an alternative configuration of the locking mechanism 340, a locking mechanism 360, which is illustrated in FIG. 41, includes a central extension 362 that is positioned between an upper extension 364 and a lower extension 366. Ends of the upper and lower extension 364, 366 extend beyond an end of the central extension 362.
The central, upper and lower extensions 362, 364, 366 each have a tab 368 extending outwardly therefrom proximate an end thereof. Since the central extension 362 is offset from the upper and lower extensions 364, 366, urging the tab 368 on the central extension 362 towards the tabs 368 on the upper and lower extensions 364, 366 causes a diameter of the locking mechanism 360 to increase and thereby allows the locking mechanism 360 to release the needle (not shown).
Because the central extension 362 is located between the upper and lower extensions 364, 366, this configuration of the locking mechanism 360 has greater symmetry than the embodiment of the locking mechanism disclosed in FIG. 35 and thereby may reduce twisting of the locking mechanism 360 during operation.
A technique for attaching the mesh assembly to the connector is directed to molding the connector over an end of the mesh assembly, such as for use with the connector illustrated in FIGS. 27-29. The connector mold is formed with an opening that is adapted to receive the end of the mesh assembly. As an alternative to molding the entire connector over the end of the mesh assembly, the invention relates to molding a connector over the end of the mesh assembly and then attaching the connector to the connector.
It is contemplated that features disclosed in this application, as well as those described in the above applications incorporated by reference, can be mixed and matched to suit particular circumstances. Various other modifications and changes will be apparent to those of ordinary skill.
