Abstract
Urinary incontinence such as stress incontinence, is alleviated in a mammal, in particular a human being, especially a woman, by correcting the internal urethral orifice and the urethra with an elastic form stable material. Such a material preferably a curable elastomer-precursor composition is injected in the body tissue surrounding the urethra, thereby correcting internal urethral orifice and the urethra substantially to its original shape, allowing the sphincter to act in a controllable way.
Claims6
A method of counteracting incontinence in a mammal, the method comprising:
- correcting the shape of the internal urethral orifice and urethra with an elastic form stable material;
- injecting a curable elastomer-precursor composition in the body tissue surrounding the urethra, wherein said curable elastomer-precursor composition comprises a silicone elastomer, a cross-linking agent, and a diluent, and wherein said curable elastomer-precursor composition is further defined as comprising between about 60% and 75% by weight based on the weight of the entire composition of poly(dimethyl siloxane), between about 2% and 5% by weight based upon the weight of the entire composition of a cross-linking agent, between about 10% and 20% by weight based upon the weight of the entire composition of a diluent, and between about 10% and 20% by weight based upon the weight of the entire composition of a radiopaque powder;
- and
- allowing said composition to cure in situ into a solid mass.
