Manually Actuated Hydraulic Sphincter

Reference#: P00150


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. 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 obtaining continence while causing the artificial sphincter to apply minimal pressure to the urethra for all conditions of the bladder. The invented apparatus: (1) automatically causes sphincter fluid pressure to increase or decrease with sensed bladder and/or abdominal pressure, and (2) is manually actuated by a patient when he or she desires to urinate. The invented apparatus can be filled with fluid, or the fluid pressure can be reset, after implantation without necessitating a surgical procedure. Patent #4571749
