Abstract
Abstract The surgical treatment of stress urinary incontinence is disclosed. The disclosed methods include: 1) a technique of probe passage to avoid injuring the bladder and to provide a more accurate and reproducible capture of the pubocervical fascia lateral to the bladder neck and urethra, 2) anchor fixation of the suspending sutures to the pubic bone to decrease the risk of suture pull through from above and to decrease post-operative pain and 3) a simple and reproducible technique to set a limited tension of the suspending sutures. A description of these methods and results of procedures with some of these methods are disclosed. Novel drill guides, suture passers, suture tensioners, and various related tools and devices for use in the surgical method are also disclosed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
43 words
A method of suspending a bladder neck comprising the steps of: securing a suture to a bone anchor; positioning said anchor in a bone without exposing said bone by way of an open surgical procedure; and suspending said bladder neck with said suture.
Claim 2
Independent Claim
43 words
A method of suspending a bladder neck comprising the steps of: securing a suture to a bone anchor; positioning said anchor in a bone without exposing said bone by way of an open surgical procedure; and suspending said bladder neck with said suture.
Claim 3
Dependent Claim
21 words
The method of claim 1, wherein said suture is secured to said anchor before said anchor is positioned in the bone.
Claim 4
Dependent Claim
21 words
The method of claim 1, wherein said suture is secured to said anchor after said anchor is positioned in the bone.
Claim 5
Dependent Claim
12 words
The method of claim 1, wherein the positioning step is accomplished percutaneously.
Claim 6
Dependent Claim
22 words
The method of claim 1, wherein the positioning step comprises positioning said anchor in a generally anterior surface of a pubic bone.
Claim 7
Dependent Claim
25 words
The method of claim 5, wherein the positioning step comprises positioning said anchor in the pubic bone approximately 2 centimeters lateral to a symphysis pubis.
Claim 8
Independent Claim
304 words
A method of suspending a bladder neck in a patient, said method comprising the steps of: securing a suture to a bone anchor, said suture having a first end and a second end; positioning said anchor in a pubic bone; grasping said suture with a probe, said probe being able to pierce tissue; advancing said probe and the first end of said suture behind the pubic bone, and through an endopelvic fascia and anterior vaginal wall adjacent to a urethra at a first point; releasing said suture within a vaginal cavity; withdrawing said probe through the endopelvic fascia and vaginal wall; advancing said probe through the endopelvic fascia and anterior vaginal wall at a second point, said second point being lateral to said first point; grasping said suture within the vaginal cavity with said probe; withdrawing the probe and the first end of said suture through the endopelvic fascia and vaginal wall; advancing said probe and the first end of said suture through the endopelvic fascia and anterior vaginal wall at a third point, said third point being medial and distal to said second point; releasing said suture within the vaginal cavity; withdrawing said probe through the endopelvic fascia and vaginal wall; advancing said probe through the endopelvic fascia and anterior vaginal wall at a fourth point, said fourth point being lateral to said third point; grasping said suture within the vaginal cavity with said probe; removing said probe and the first end of said suture from the patient; releasing said suture from said probe; applying tension to the first and second ends of said suture; tying the first and second ends of said suture to suspend a first side of the bladder neck; and repeating the foregoing steps on a second side of the bladder neck to form a bladder neck suspension sling.
Claim 9
Independent Claim
304 words
A method of suspending a bladder neck in a patient, said method comprising the steps of: securing a suture to a bone anchor, said suture having a first end and a second end; positioning said anchor in a pubic bone; grasping said suture with a probe, said probe being able to pierce tissue; advancing said probe and the first end of said suture behind the pubic bone, and through an endopelvic fascia and anterior vaginal wall adjacent to a urethra at a first point; releasing said suture within a vaginal cavity; withdrawing said probe through the endopelvic fascia and vaginal wall; advancing said probe through the endopelvic fascia and anterior vaginal wall at a second point, said second point being lateral to said first point; grasping said suture within the vaginal cavity with said probe; withdrawing the probe and the first end of said suture through the endopelvic fascia and vaginal wall; advancing said probe and the first end of said suture through the endopelvic fascia and anterior vaginal wall at a third point, said third point being medial and distal to said second point; releasing said suture within the vaginal cavity; withdrawing said probe through the endopelvic fascia and vaginal wall; advancing said probe through the endopelvic fascia and anterior vaginal wall at a fourth point, said fourth point being lateral to said third point; grasping said suture within the vaginal cavity with said probe; removing said probe and the first end of said suture from the patient; releasing said suture from said probe; applying tension to the first and second ends of said suture; tying the first and second ends of said suture to suspend a first side of the bladder neck; and repeating the foregoing steps on a second side of the bladder neck to form a bladder neck suspension sling.
Claim 10
Dependent Claim
94 words
The method of claim 7, wherein said probe comprises a handle, an elongate tubular probe guide extending in a distal direction from the handle, an elongate pointed probe axially movably disposed within the tubular probe guide, and a recess on the pointed probe and an opening on the tubular probe guide for receiving said suture, said grasping and releasing steps being accomplished by axially moving the pointed probe within the tubular probe guide to bring the recess on the pointed probe into and out of alignment with the opening on the tubular probe guide.
Claim 11
Dependent Claim

The method of claim 7, wherein the positioning step is accomplished using a bone anchor implantation device, said bone anchor implantation device comprising a housing, at least one probe mounted to the housing, and a guide channel extending through the housing, the positioning step comprising piercing tissue with said at least one probe of the bone anchor implantation device to contact bone so that the guide channel is placed over the pubic bone into which said anchor is to be positioned.
Claim 12
Dependent Claim
49 words
A minimally invasive method of suspending a bladder neck, comprising the steps of: securing a suture to a bone anchor; locating a generally anterior surface of a pubic bone; positioning the anchor in the generally anterior surface of the pubic bone; and suspending the bladder neck with the suture.
