Abstract

A system for supporting an anatomical structure of the pelvis includes a surgical implant for providing support to the anatomical structure of the pelvis. The surgical implant includes a first tissue anchor including a plurality of projections adapted for tissue fixation, a second tissue anchor including a plurality of projections adapted for tissue fixation, and a sub-urethral support having first and second ends, the first and second tissue anchors extending from the first and second ends of the sub-urethral support. The system also includes an introducer for delivering the first tissue anchor to a desired anchoring site of the pelvis.

Claims

1. A surgical kit for treating urinary incontinence, the surgical kit comprising:

a surgical implant for providing support to the urethra of the patient for treating urinary incontinence, the surgical implant including;

a first anchor having an introducer aperture and including an anchor tip and a plurality of anchor features adapted for tissue fixation;

a second anchor; and

a sub-urethral support having first and second ends, the first and second anchors being connected to the first and second ends of the sub-urethral support; and

an introducer for delivering the first tissue anchor to an anchoring site of the pelvis in association with a procedure for treating urinary incontinence, the introducer having a handle and a shaft secured to the handle, the shaft including a tip forming a recess that is centered on the longitudinal axis of the tip and configured to receive the first anchor such that a portion of the tip passes through the introducer aperture of the first anchor and extends distally from the anchor tip when the first soft tissue anchor is received in the recess.

2. The surgical kit of claim 1, wherein the tip includes a first prong and a second prong forming the recess between the first and second prongs.

3. The surgical kit of claim 2, wherein the introducer is adapted to receive the first tissue anchor between the first and second prongs.

4. The surgical kit of claim 2, wherein each of the first and second prongs of the introducer has an angled end.

5. The surgical kit of claim 1, wherein the recess has a first wall and a second portion of the tip is longer than the first wall such that the second portion of the tip extends distally relative to the first wall.

6. The surgical kit of claim 1, wherein the shaft of the introducer is configured to maintain the first tissue anchor in a pre-determined orientation relative to the introducer.

7. The surgical kit of claim 1, wherein the first and second anchors are secured directly to the sub-urethral support.

8. The surgical kit of claim 1, wherein the shaft of the introducer is curved.

9. The surgical kit of claim 1, wherein the suburethral support is comprised of mesh.

10. The surgical kit of claim 1, wherein the tip of the shaft of the introducer comprises plastic material.

11. A method of treating urinary incontinence by supporting the urethra comprising:

providing an introducer and a surgical implant configured for treating, urinary incontinence by supporting the urethra, where a tip of an introducer is inserted through an introducer aperture in a first anchor of a surgical implant such that the first anchor is received in a longitudinally extending recess of the tip of the introducer;

introducing the first anchor into anatomy of the pelvis through a vaginal incision using the introducer;

introducing a second anchor into anatomy of the pelvis such that a suburethral support of the surgical implant is anchored between the first and second anchors in order to provide support to anatomy of the pelvis, wherein the first anchor is received on the introducer with a portion of the introducer passing through the introducer aperture and extending distally from a distal end of the first anchor.

12. The method of claim 11, further comprising inserting the first anchor between a first prong and a second prong of the tip of the introducer, the first and second prongs forming the recess.

13. The method of claim 11, wherein the first and second prongs of the introducer comprise plastic material.

14. The method of claim 11, wherein each of the first and second prongs between which the first anchor is inserted has an angled end.

15. The method of claim 11, wherein the recess in which the first anchor is received has a first wall and a second portion of the tip is longer than the first wall such that the second portion of the tip extends distally relative to the first wall.

16. The method of claim 11, further comprising maintaining the first tissue anchor in a pre-determined orientation relative to the introducer during introduction of the first anchor into anatomy of the pelvis.

17. The method of claim 11, wherein the first and second anchors being introduced into anatomy of the pelvis are secured directly to a sub-urethral support of the surgical implant.

18. The method of claim 11, wherein the introducer being used to introduce the first anchor into anatomy of the pelvis includes a curved shaft.

19. The method of claim 11, wherein the implant provides support to anatomy of the pelvis with a suburethral support comprised of mesh.

20. The method of claim 11, further comprising releasing the first anchor from the introducer after introducing the first anchor into anatomy of the pelvis through a vaginal incision using the introducer.
