Abstract
A suburethral sling device and method for treating female urinary stress incontinence which is anatomically configured to implant into the lower abdomen of a female in a manner providing support to mid-urethral and bladder neck sphincteric continence sites with the sling defining in part, mesh and tissue remodeling portions. The sling is deployed via a sling transfer instrument having distal and proximal ends with the instrument comprising in part a progressively curved shaft portion positioned between the distal and proximal ends. An insertion handle of the transfer instrument is secured to the curved metal shaft section guiding the shaft tip through the tissues of the abdomen in an anterior/posterior direction as well as a cephalad/caudad direction.

9. A surgical instrument for treating female urinary stress incontinence comprising:
-
a) a sling contoured to the anatomical configuration of the mid-urethra, proximal urethra, bladder neck and base of the bladder for implanting into the abdomen of a female providing support to mid-urethral and bladder neck sphincteric continence sites as well as support for the base of the bladder to restore the normal anatomical relationship of the urethra to the bladder, said sling defining in part a mesh section fixedly attached to and surrounding a tissue remodeling portion; and b) a sling transfer instrument having a distal end and a proximal end, said instrument defining in part a progressively curved shaft portion positioned between distal and proximal ends with a first detachable handle located at its proximal end, a second attachable handle positioned said shaft'"'"'s distal end, and a means for attaching said sling to the proximal end of said shaft. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

20. A transvaginal deployment method for treating female urinary stress incontinence comprising:
-
a) providing a sling defining in part a tissue remodeling portion and a mesh section and contoured to the anatomical configuration of the mid-urethra, proximal urethra and base of the bladder; b) providing a sling transfer instrument having a distal end and a proximal end with a progressively curved shaft portion positioned between said distal and proximal ends with a detachable insertion handle located at the instrument'"'"'s proximal end; c) positioning the sling transfer instrument'"'"'s detachable insertion handle within the human hand and using said handle to guide the curved tip at the instrument'"'"'s distal end through the vaginal wall, behind the pubic bone, through the abdominal wall and exiting the abdominal wall below the pubic hair line; d) disengaging the detachable insertion handle located at the instrument'"'"'s proximal end from the progressively curved portion of sling transfer tool; e) attaching a sling transfer handle to the exited curved tip; f) attaching the sling of step (a) to the sling transfer instrument'"'"'s proximal end; g) positioning the sling transfer instrument'"'"'s sling transfer handle within the human hand and using said handle to retrieve or otherwise pull the sling attached to the instrument'"'"'s proximal end through the vaginal wall, behind the pubic bone, through the tissues of the abdomen traversing perforations made in the vaginal wall and abdominal wall previously in step (c); h) providing a second sling transfer instrument and repeating steps (c) through (g) on a side of the body to cause the sling to be positioned to form a U-shape around mid-urethral and bladder neck sphincteric continence sites; i) displacing said sling from the sling transfer instrument subsequent to said sling'"'"'s passage through the abdominal wall. - View Dependent Claims (21)
