Abstract

A surgical implant for treating female urinary incontinence includes a suburethral support, first and second soft tissue anchors, and an elongated member. The first and second soft tissue anchors are connected to first and second opposite ends of the suburethral support, each anchor having a central portion, a proximal end, and a tip on a distal end of the anchor, and a plurality of projections extending from the central portion at longitudinally spaced locations along a length extending between the proximal and distal ends of the central portion. The elongated member extends between the proximal end of the first soft tissue anchor and the first end of the suburethral support to connect the anchor to the support and enable the position of the anchor with respect to the support to be adjusted.

Claims

1. A surgical implant for treating female urinary incontinence, comprising:

a suburethral support;

first and second soft tissue anchors connected to the first and second opposite ends of the suburethral support, each anchor having a central portion, a proximal end, and a tip on a distal end of the anchor, and a plurality of projections extending from the central portion at longitudinally spaced locations along a length extending between the proximal and distal ends of the central portion;

a first elongated member coupled to and extending between the proximal end of the first soft tissue anchor and the first end of the suburethral support; and

a second elongated member coupled to and extending between the proximal end of the second soft tissue anchor and the second end of the suburethral support.

2. The surgical implant of claim 1 wherein each of the first and second elongated members is a filamentary member.

3. The surgical implant of claim 2 wherein the filamentary member extends through a plurality of openings in the first end of the support.

4. The surgical implant of claim 3 and further including a knot in the filamentary member securing the filamentary member to the support.

5. The surgical implant of claim 4 wherein the suburethral support has smooth edges and tapered first and second opposite ends.

6. The surgical implant of claim 1 wherein the first elongated member extends through a plurality of openings in the first end of the support.

7. The surgical implant of claim 6 and further including a knot in the first elongated member securing the first elongated member to the support.

8. The surgical implant of claim 1 wherein the first and second anchors include at least ten longitudinally spaced projections.

9. The surgical implant of claim 8 wherein the first and second anchors include projections extending from opposite sides of the central portion.

10. The surgical implant of claim 1 wherein the suburethral support has tapered first and second opposite ends.

11. The surgical implant of claim 1 wherein the suburethral support has smooth edges.

12. The surgical implant of claim 1 wherein the tips on the first and second anchors include:

a conical shape;

a truncated distal end;

a proximal shoulder; and

an introducing tool tip-receiving bore extending from the proximal shoulder through the truncated distal end.

13. The surgical implant of claim 12 wherein:

the proximal shoulder of each tip has a first diameter; and

the central portion of each tip has a second diameter that this less than the first diameter.

14. The surgical implant of claim 12 wherein each tip is a unitary member.

15. The surgical implant of claim 12 wherein an opening of the bore at the proximal shoulder of each tip is adjacent to a side of the central portion.

16. The surgical implant of claim 12 and further including an introducer tool including:

a handle; and

an elongate and curved body extending from the handle, including;

a narrowed portion on a distal end of the body, the narrowed portion sized to extend through the bore in the tip of at least one of the first and second anchors;

an abutment on a proximal end of the narrowed portion for engaging the proximal shoulder on the anchor; and

a tip on a distal end of the narrowed portion that extends beyond the truncated distal end of the tip of the anchor when the narrowed portion of the body extends through the bore in the tip of the anchor.

17. In combination, a surgical implant for treating female urinary incontinence and an introducer tool for inserting the implant into a patient, comprising:

a surgical implant, including;

a suburethral support having first and second opposite ends;

first and second soft tissue anchors connected to the first and second opposite ends of the suburethral support, each anchor having;

a central portion with a proximal end;

a conical tip on a distal end of the central portion, the tip having a truncated distal end, a proximal shoulder, and an introducing tool tip-receiving bore extending from the proximal shoulder through the truncated distal end; and

a plurality of projections extending from the central portion at longitudinally spaced locations along a length of the central portion between the proximal and distal ends; and

a first filamentary member coupled to the proximal end of the first soft tissue anchor and the first end of the suburethral support and engaged with a plurality of openings in the suburethral support;

a second filamentary member coupled to the proximal end of the second soft tissue anchor and the second end of the suburethral support and engaged with a plurality of openings in the suburethral support; and

an introducer tool, including;

a handle; and

an elongate and curved body extending from the handle, including;

a narrowed portion on a distal end of the body, the narrowed portion sized to extend through the bore in the tip of at least one of the first and second anchors;

an abutment on a proximal end of the narrowed portion for engaging the proximal shoulder on the anchor; and

a tip on a distal end of the narrowed portion that extends beyond the truncated distal end of the tip of the anchor when the narrowed portion of the housing extends through the bore in the tip of the anchor.

18. The invention of claim 17 and further including a knot in each of the first and second filamentary members securing the filamentary members to the support.

19. The invention of claim 18 wherein the first and second anchors include at least ten longitudinally spaced projections.

20. The invention of claim 19 wherein the first and second anchors include projections extending from opposite sides of the central portion.

21. The invention of claim 20 wherein the suburethral support has tapered ends.

22. The invention of claim 21 wherein the suburethral support has smooth edges.
