Abstract

A female urinary stress incontinence remedy in which endopelvic fascia attached to either side of the urethra is elevated and held in place by means of a pair of anchors comprised of upper and lower stays interconnected by suture and surgically positioned on either side of the urethra with the upper stay positioned above the rectus fascia and the lower anchor stay engaging the endopelvic fascia, exposed by aligned insisions in the vaginal wall.

Claims

1. A method of treating female urinary stress incontinence comprising the steps of:

a. making at least two incisions in the vaginal wall with one incision on each side of and parallel to the urethra, with each incision exposing endopelvis fascia,

b. assembling at least two anchors with each anchor having an upper stay affixed to a suture and a lower stay having an opening for slidably receiving the suture,

c. loading an anchor into a cannula,

d. inserting the cannula into the vagina to pierce the endopelvic fascia exposed by the incision to the one side of the urethra and continuing on to pierce the rectus muscle and the rectus fascia above the pubis,

e. discharging the upper stay above the rectus fascia,

f. withdrawing the cannula leaving the upper stay in place with the suture extending from the stay through the rectus fascia, rectus muscle, and through the incision in the vaginal wall,

g. drawing the lower stay up on the suture to elevate tissue in the vicinity of the urethra

h. securing the lower stay to the suture when the correct degree of elevation is achieved, and

i. repeating steps c through h through the incision on the other side of the urethra.

2. The method of claim 1 in which each incision is restricted to the epithelium of the vaginal wall.

3. A method of treating female urinary stress incontinence comprising the steps of:

a. making two incisions in the vaginal wall with one incision on each side of the urethra, with each incision exposing endopelvic fascia,

b. assembling two anchors with each anchor having an upper stay affixed to a suture and a lower stay having an opening for slidably receiving the suture,

c. positioning the upper stay above the rectus fascia by insertion through the endopelvic fascia exposed by the incision to the one side of the urethra and continuing on to pierce the rectus muscle and the rectus fascia above the pubis, with the suture extending from the upper stay through the rectus fascia, rectus muscle, and through the incision in the vaginal wall,

d. drawing the lower stay up on the suture to elevate tissue in the vicinity of the urethra

e. securing the lower stay to the suture when the correct degree of elevation is achieved, and

f. repeating steps c through e through the incision on the other side of the urethra.

4. A method of treating female urinary stress incontinence comprising the steps of:

a. making two incisions in the vaginal wall with one incision on each side of the urethra, with each incision restricted to the epithelium of the vaginal wall,

b. assembling two anchors with each anchor having an upper stay affixed to a suture and a lower stay having an opening for slidably receiving the suture,

c. positioning the upper stay above the rectus fascia by insertion through the incision to the one side of the urethra and continuing on to pierce the rectus muscle and the rectus fascia above the pubis, with the suture extending from the upper stay through the rectus fascia, rectus muscle, and through the incision in the vaginal wall,

d. drawing the lower stay up on the suture to elevate tissue in the vicinity of the urethra

e. securing the lower stay to the suture when the correct degree of elevation is achieved, and

f. repeating steps c through e through the incision on the other side of the urethra.

5. An implant kit for treating female urinary stress incontinence comprising a pair of anchors, each anchor comprising an upper stay affixed to a length of suture, and a lower stay slidably received on the suture through an opening in the lower stay, the lower stay being deformable by crimping in the vicinity of the opening for securement to the suture.

6. A kit as defined in claim 5 in which the stays are formed of biologically compatible plastic.

7. A kit as defined in claim 6 in which the stays are formed of polypropylene.

8. A kit as defined in claim 5 in which the stays are formed of biologically compatible metal.

9. A kit as defined in claim 8 in which the stays are formed of titanium.

10. An implant kit for treating female urinary stress incontinence comprising a pair of anchor assemblies, each anchor assembly comprising an upper stay affixed to a length of suture, and a lower stay slidably received on the suture through an opening in the lower stay, the lower stay being deformable by crimping in the vicinity of the opening for securement to the suture, a cannula for receiving each anchor assembly for implanting each assembly, and a tool for crimping the lower stay for securement to the suture.
