ABSTRACT:
A unitary, inflatable penile prosthesis system includes a prosthesis implantable within the corpus cavernosum of the penis in order to alleviate erectile impotency. A tubular enclosure includes a distal pump, a medial pressurizable chamber, and a proximal fluid reservoir. A pump draws fluid from the reservoir through an external fluid passageway into the pressurizable chamber. The pressurizable chamber is defined by an internal, tubular, substantially nondistensible portion and a concentric tubular sleeve. The nondistensible portion is crimped so that it may expand in diameter. Upon expansion, the prosthesis assumes a straight, erect state. The sleeve may elastically bias the nondistensible portion to its flaccid state. Fluid for filling the nondistensible portion may be stored in a rear fluid reservoir having a rigid internal stabilizer.
