Abstract
Apparatus and a non-surgical method for hypodermically implanting a genitourinary prosthesis comprising an extensible, inflatable 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. Hypodermic positioning, injecting and inflating instruments are also disclosed for implant of the containment membrane and for percutaneously infusing the membrane with bicompatible fluid or particulate matter. The containment membrane functions as an envelope for retaining the fluid or particulate matter therewithin while controllably and advantageously increasing localized tissue volume and simultaneously preventing the migration of such fluid or particles. Accordingly, an increased passive occlusive pressure may be applied to the patient's urethra to achieve continence.
