IMPLANTABLE ARTIFICIAL SPHINCTER SYSTEM Abstract This invention relates to an implantable artifi- cial sphincter system for reversibly occluding a body passageway, which system includes occlusion means, pump means, and the unique feature of a fluid capacitor disposed on a control assembly for the system, which is capable of increasing volume under fluid pressure. The fluid capacitor is connected with the occlusion means in such fashion that said occlusion means will remain substantially inflated during short, but significant, pressure increases, but will at least partially deflate upon the advent of prolonged but moderate pressure increases on the body passageway. While in its prefer- red embodiment no other fluid containing component is needed, if desired a volume compensator can also be included in the system. A valve preferably of the magnetic type can also be included for activating or deactivating the system.
