ABSTRACT:
An implantable hydraulic urinary sphincter system is disclosed for maintaining continence in those patients unable to control or stop inadvertent urinary flow. The invented apparatus generally consists of an artificial urinary sphincter and a control means for automatically increasing or decreasing sphincter pressure with sensed bladder and/or intra-abdominal pressure. An improved mechanical actuation means is also disclosed which allows the patient to urinate. To urinate the patient presses a push button centered on a septum located on the outer wall of the subcutaneously implanted control unit.
