Abstract
A non-surgical method for implanting a genitourinary prosthesis comprising an extensible, inflatable tissue expanding containment membrane to be located between the urethra and the subcutaneous corpus spongiousum of a patient to overcome urinary incontinence by means of localized, controlled tissue volume increase. A disposable cartridge assembly is also disclosed for hypodermically positioning, injecting and inflating the containment membrane and for percutaneously infusing the membrane with biocompatible fluid or suspended particulate matter. The containment membrane functions as an envelope for retaining the fluid or suspended particulate matter therewithin while simultaneously increasing localized tissue volume and advantageously preventing the migration of such fluid or particles through the patient's body. Accordingly, an increased passive occlusive pressure may be applied to the patient's urethra to return the patient to continence.
