Abstract

A surgical system includes an implant for supporting pelvic anatomy. The implant includes a first suspending member, a second suspending member, and a support portion. The first and second suspending members are formed as flexible strips that extend from proximal to distal ends, the distal ends including first and second anchor portions, respectively, for anchoring to soft tissue in a space defined by a pelvis. The support portion is formed as a flexible strip that extends from a first end to a second end, the support portion having a first opening toward the first end of the support portion, the first opening slidably receiving the proximal end of the first suspending member such that a length of the first suspending member between the first anchor portion and the first end of the support portion is adjustable.

Claims

1. A surgical system including an implant for supporting pelvic anatomy, the implant comprising:

a first suspending member formed as a flexible strip that extends from a proximal end to a distal end, the distal end including a first anchor portion for anchoring to soft tissue in a space defined by a pelvis;

a second suspending member formed as a flexible strip that extends from a proximal end to a distal end, the distal end including a second anchor portion for anchoring to soft tissue in a space defined by a pelvis; and

a support portion formed as a flexible strip that extends from a first end attached to the first suspending member to a second end attached to the second suspending member, the support portion having a first opening toward the first end of the support portion, the first opening slidably receiving the proximal end of the first suspending member such that a length of the first suspending member between the first anchor portion and the first end of the support portion is adjustable.

2. The system of claim 1, wherein the support portion has a second opening toward the second end of the support portion, the second opening slidably receiving the proximal end of the second suspending member such that a length of the second suspending member between the second anchor portion and the second end of the support portion is adjustable.

3. The system of claim 1, wherein the support portion defines a length between the first and second ends and the first opening is a slot that extends substantially perpendicular to the length of the support portion.

4. The system of claim 1, wherein the support portion has a second opening positioned next to the first opening, the first and second openings receiving the proximal end of the first suspending member such that a length of the first suspending member between the first anchor portion and the first end of the support portion is selectively fixed.

5. The system of claim 4, wherein the first and second openings are each formed as slots.

6. The system of claim 1, wherein at least the first suspending member is formed of mesh material.

7. The system of claim 1, wherein the first anchor portion is formed of mesh material.

8. The system of claim 1, wherein the first anchor portion is integral with the first suspending member.

9. The system of claim 1, wherein the support portion has a length of about 20 mm.

10. The system of claim 1, wherein first and second suspending members each define a width, the support portion defines a width, and the widths of the first and second suspending members are each less than the width of the support portion.

11. The system of claim 1, wherein the support portion is formed of mesh.

12. The system of claim 1, wherein the first anchor portion is radially expandable to grip the soft tissue.

13. The system of claim 12, further comprising an introducer tool for receiving the first anchor portion such that the first anchor portion is radially confined.

14. A method for supporting a urethra of a patient, the method comprising:

making an incision on an upper wall of a vagina of the patient;

inserting a distal end of a first suspending member on a first side of the urethra of the patient, the distal end including a first anchor portion;

anchoring the first anchor portion in soft tissue of the pelvis without penetrating the rectus sheath;

inserting a distal end of a second suspending member on a second side of the urethra, the distal end including a second anchor portion;

anchoring the second anchor portion in soft tissue of the pelvis without penetrating the rectus sheath;

providing a support portion attached between end portions of the first and second suspending members and slidably inserting a proximal end of the first suspending member in a first opening of the support portion;

adjusting a length of the first suspending member between the anchor portion and the support portion; and

suspending the support portion from the first and second suspending members such that the support portion passes loosely under the urethra.

15. The method of claim 14, further comprising slidably receiving a proximal end of the second suspending member in a second opening of the support portion and adjusting a length of the second suspending member between the second anchor portion and the second end of the support portion.

16. The method of claim 14, further comprising slidably receiving the proximal end of the first suspending member in a second opening of the support portion that is positioned next to the first opening in the support portion such that a length of the first suspending member between the first anchor portion and the first end of the support portion is selectively fixed.

17. The method of claim 14, wherein anchoring the first anchor portion in soft tissue of the pelvis without penetrating the rectus sheath comprises radially confining the first anchor portion with an introducer, inserting the distal end of the first anchor portion into soft tissue of the pelvis with the introducer, and releasing the first anchor portion from the introducer such that the first anchor portion radially expands to grip the soft tissue.
