ABSTRACT:
An active, as opposed to a passive, sphincteric system to be implanted within or near the periurethral tissues of an incontinent patient. The system includes a genitourinary prosthesis comprising an inflatable (and deflatable) balloon (rather than a cuff) which is percutaneously infused with and inflated by a supply of hydraulic fluid or suspended particulate matter to increase both the localized tissue density proximal to the urethra and the passive occlusive pressure applied to the urethra for returning the patient to continence. The system includes an accumulator or reservoir and a check valve located between the accumulator and the balloon to control the flow of fluid or suspended particles therebetween. The check valve may be manually opened, whereby the balloon shrinks and the accumulator swells. Subsequently, the accumulator may be manually compressed, whereby fluid or suspended particles are transferred back to the balloon, by hydrostatic pressure, to reinflate the balloon. Positioning and inflating instrumentation is also disclosed by which to implant the sphincteric system according to a relatively simple insertion process.
