Method and articles for treatment of stress urinary incontinence

Abstract

Improved methods and apparatuses for treatment of incontinence or pelvic organ prolapse are provided. A neo ligament for increasing the supportive function of the tissues supporting the urethra, bladder neck, or rectum is disclosed. Methods of using such a neoligament to treat incontinence are disclosed. Additionally, a self tensioning elastic tissue bolster for support of the tissues that support the urethra, rectum, and bladder neck are disclosed. A method of treating incontinence by injecting proliferative agents into supportive structures is disclosed. Methods and apparatus for transvaginal and transperitieai pelvic floor bolster treatment of incontinence and bladder pillar systems are also disclosed.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to urogenital medicine and surgery.[0003]2. Description of the Related Art[0004]Over 13 million American men and women of all ages suffer from urinary incontinence. The social implications for an incontinent patient include loss of self-esteem, embarrassment, restriction of social and sexual activities, isolation, depression and, in some instances, dependence on caregivers. Incontinence is the most common reason for institutionalization of the elderly.[0005]The urinary system consists of the kidneys, ureters, bladder and urethra. The bladder is a hollow, muscular, balloon-shaped sac that serves as a storage container for urine. The bladder is located behind the pubic bone and is protected by the pelvis. Ligaments hold the bladder in place and connect it to the pelvis and other tissue. FIG. 1 schematically illustrates female anatomy. The urethra 16 is the tube that passes urine from the bladder 14 ...

AI Technical Summary

Benefits of technology

The present invention describes a way to create a synthetic tissue or composite tissue / synthetic structure that can support the ureter, rectum, or pelvic floor muscles during a stress event such as urinary or fecal incontinence. This is done using a neoligament which requires minimal surgery and can be easily implanted. The invention also describes a self-tensioning elastic tissue bolster that can be implanted to treat incontinence. Additionally, the invention includes a method to shrink collagen in the tissues that support the ureter, bladder, rectum, and pelvic floor by using an injectable agent. This treatment is minimally invasive and has minimal adverse side effects.

Problems solved by technology

Other factors, such as trauma to the urethral area, neurological injury, hormonal imbalance or medication side-effects, may also cause or contribute to incontinence.

Inappropriate bladder contractions and weakened sphincter muscles usually cause this type of incontinence.

Functional incontinence results when a person has difficulty moving from one place to another.

Although serious complications associated with sling procedures are infrequent, they do occur.

All of these injectable agents have the disadvantage of requiring multiple repeated treatments to maintain efficacy.

This leads to localized inflammation, which leads to the wound healing process.

This results in a deposition of new collagen, which shrinks as it heals.

These techniques have not been applied to urologic disorders.
