Abstract

Disclosed are single-incision surgical procedures for treatment of urinary incontinence and/or pelvic floor disorders and related uses, devices, kits, and methods. Implants are also disclosed for use in the exemplary procedures. In certain embodiments, soft tissue anchors are used to anchor the surgical implants to obturator membranes of a patient.

Claims

1. A surgical sling assembly for treating urinary incontinence in a patient, comprising:

a surgical sling for supporting at least one of a urethra and a bladderneck of the patient, and

a flexible sling housing disposed about a first end of the sling, wherein

the sling housing comprises a through-aperture having a proximal end and a distal end, and being curved between said proximal end and said distal end,

wherein the sling is interdisposed between a top half of the sling housing and a bottom half of the sling housing, and

wherein the top half of the sling housing includes a plurality of cavities, and the bottom half of the sling housing includes protrusions for interfitting with the plurality of cavities.

2. The assembly of claim 1, wherein the sling housing includes a ring for coupling to a delivery device, and at least two legs radially extending from the ring for anchoring to soft tissue.

3. The assembly of claim 2, wherein the legs adjoin at an angle and the legs can flex to vary the angle.

4. The assembly of claim 2, wherein the legs extend beyond a width of the sling.

5. The assembly of claim 2, wherein the ring is configured at an angle with respect to a plane extending through the legs and the ring can flex to vary the angle.

6. The assembly of claim 1, wherein the aperture lies in a plane extending through the sling.

7. The assembly of claim 1, wherein the aperture lies in a plane perpendicular to a plane extending through the sling.

8. The assembly of claim 1, further comprising a second sling housing disposed about a contra-lateral end of the sling, wherein the first end and the contra-lateral end of the implant span a length between a first obturator foramen and a contra-lateral obturator foramen of the patient.

9. The assembly of claim 1, further comprising

an end termination formed directly about an end of the implant and comprises a through-aperture having a proximal end and a distal end, and being curved between said proximal end and said distal end.

10. The assembly of claim 9, wherein the end termination is molded directly about an end of the implant.

11. The sling assembly of claim 1, wherein the curved sling housing has a mid-section diameter greater than that of the proximal and distal ends of the through-aperture.

12. A method for treating urinary incontinence in a patient, comprising

providing an implant having at least one tanged portion formed as a unitary body with the implant and at least one portion in which a plurality of transverse strands of the implant extend beyond a width of lateral strands of the implant;

creating an incision in the vaginal wall of the patient,

coupling an implant to a delivery device,

inserting the delivery device through the incision in the vaginal wall via the external vaginal opening of the patient,

guiding the device to a location beneath the patient'"'"'s epidermis, and

securing, by the at least one tanged portion, the implant to the patient'"'"'s soft tissue such that at least a portion of the sling extends to a position posterior to the bladder neck.

13. The method of claim 12, wherein the transverse strands extend between about 2 mm and about 4 mm beyond the width of the lateral strands of the implant.
