Methods and devices for the treatment of urinary incontinence

Abstract

Methods and devices for treating female stress urinary incontinence are disclosed. The methods include transvaginally accessing the pelvic cavity and introducing a suburethral sling into the retropubic space. In some embodiments the ends of the sling are attached to an anatomical support structure. In other embodiments, the ends of the suburethral sling are not attached to an anatomical support structure. The devices include a surgical instrument for blunt dissection of the pelvic cavity which includes a curved shaft and a blunt distal end. A hook deployment device may optionally be attached to the surgical instrument.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the priority to and the benefit of U.S. provisional patent application Ser. No. 60 / 209,234 filed on Jun. 5, 2000, which is incorporated herein by reference in its entirety.TECHNICAL FIELD [0002] This invention relates to methods and devices for the treatment of female urinary incontinence. BACKGROUND INFORMATION [0003] Stress urinary incontinence in women may be caused by urethral hypermobility. Hypermobility is a condition in which the pelvic floor fails to properly support an area between the bladder neck and mid-urethra, thus permitting the urethra to descend from its normal anatomic position in response to increases in intra-abdominal pressure, resulting in urinary incontinence. [0004] Surgical procedures for stabilizing the urethra include suburethral slings and needle suspensions. In some sling procedures, a suburethral sling is placed around the posterior side of the urethra and the ends are attached to an...

Benefits of technology

[0009] It is an object of this invention to provide instruments and methods for treating female stress urinary incontinence through transvaginal access and by blunt dissection. It is another object of this invention to provide instruments and methods for deploying sutures and/or slings in a surgical procedure, with reduced risk of accidental puncturing of the surgeon's fingers or injury to the patient's bladder and/or other abdominal organs.

[0010] In one another aspect, the present invention provides surgical instruments adapted for use in procedures to treat female urinary incontinence. The instrument includes a handle and a curved shaft that extends in a distal direction from the handle. The instrument is adapted to access interior tissue within a human body, such as the pelvic cavity. In one embodiment, the handl

Hypermobility is a condition in which the pelvic floor fails to properly support an area between the bladder neck and mid-urethra, thus permitting the urethra to descend from its normal anatomic position in response to increases in intra-abdominal pressure, resulting in urinary incontinence.

The introduction of such foreign objects into bone, however, presents a risk of bone marrow infection and/or pubic osteitis.

Because suspension needles and suture carriers include a sharp tip, there is a danger that the needle or carrier may wound lar
