Procedure for treating urinary incontinence, comprises using packing prostheses of biocompatible hydrogel implanted round outside of urethra

摘要

The procedure uses one or more packing prostheses (28, 30) in the form of a partial cylinder or sphere made from a hydrophilic polymer that forms a hydrogel in the presence of water, so that it expands after implantation. It is inserted round the patient's urethra (10) coaxially with the urethra's inner surface and closes the urethra when the patient exercises voluntary control over an exterior urethral sphincter (18).
