Abstract

A system configured to treat urinary incontinence includes an implant configured to support a urethra, a tensioning member connected to the implant, an elongated fixation member connected to the tensioning member, and an anchor connected to the elongated fixation member. The anchor includes a body extending between a penetration end and an introducer end, a cuff configured to slide relative to the body, and a plurality of expandable body segments coupled between the cuff and the penetration end. Movement of the cuff toward the penetration end radially expands the expandable body segments.

Claims

1. A system configured to treat urinary incontinence, the system comprising:

an implant configured to support a urethra;

a tensioning member connected to the implant;

an elongated fixation member connected to the tensioning member; and

an anchor connected to the elongated fixation member, the anchor comprising a body extending between a penetration end and an introducer end, a cuff configured to slide relative to the body, and a plurality of expandable body segments coupled between the cuff and the penetration end;

wherein movement of the cuff toward the penetration end radially expands the expandable body segments.

2. The system of claim 1, wherein the tensioning member comprises one of a knot assembly and a zip tie assembly.

3. The system of claim 2, wherein the tensioning member is configured to adjust a length of the elongated fixation member and thus adjust a tension of the implant relative to the urethra.

4. The system of claim 1, wherein the elongated fixation member comprises one of a mesh material and a suture material.

5. The system of claim 1, wherein the cuff comprises a ring disposed around the body of the anchor.

6. The system of claim 1, wherein the cuff is configured to be moved manually.

7. The system of claim 1, wherein the cuff is configured to be moved electro-mechanically.

8. The system of claim 1, wherein the anchor comprises a substantially cylindrical shape when the cuff is located adjacent to the penetration end and a substantially disc shape when the cuff is moved distally toward the penetration end.

9. The system of claim 1, comprising:

a first tensioning member connected to a first end of the implant and a second tensioning member connected to a second end of the implant;

a first elongated fixation member connected to the first tensioning member and a second elongated fixation member connected to the second tensioning member; and

a first anchor connected to the first elongated fixation member and a second anchor connected to the second elongated fixation member.

10. The system of claim 9, wherein each tensioning member is configured to adjust a length of the elongated fixation member to which it is connected and thus adjust a tension of the implant relative to the urethra.

11. A method of surgically treating urinary incontinence in a patient, the method comprising:

inserting an anchor into a membrane of an obturator foramen of the patient;

moving a component of the anchor in an axial direction and deploying a plurality of expandable body segments in a radial direction, thus securing the anchor to the membrane;

placing a support member relative to a urethra of the patient; and

connecting the support member to the anchor.

12. The method of claim 11, comprising sliding a cuff of the anchor toward a penetration end of the anchor.

13. The method of claim 11, wherein the cuff is disposed around a body of the anchor and is slideable relative to the body of the anchor.

14. The method of claim 11, further comprising:

connecting a tensioning member between the support member and the anchor; and

adjusting tension of the support member relative to the urethra with the tensioning member.

15. A method of surgically treating urinary incontinence in a patient, the method comprising:

inserting an anchor into a membrane of an obturator foramen of the patient;

moving a component of the anchor in an axial direction and deploying a plurality of expandable body segments in a radial direction, thus securing the anchor to the membrane;

placing a support member relative to a urethra of the patient;

connecting a tensioning member between the support member and the anchor; and

adjusting tension of the support member relative to the urethra with the tensioning member.

16. The method of claim 15, comprising inserting an anchor into a membrane of each of a pair of obturator foramen of the patient;

and

connecting a first tensioning member between the support member and a first one of the anchors and connecting a second tensioning member between the support member and a second one of the anchors; and

adjusting tension of the support member relative to the urethra with the first and second tensioning members.

17. The method of claim 16, comprising adjusting tension of the support member relative to the urethra by selectively shortening each of the first and second tensioning members.
