ABSTRACT:
A technique for the treatment of male impotence. The apparatus to be implanted in the corpus cavernosum of the penis is a cylinder of an implantable polymer. The cylinder is generally flexible and has a plurality of transitions from a lesser diameter to a greater diameter. As the cylinder is filled with fluid under pressure, the areas of lesser diameter tend to expand, thereby effectively lengthening the cylinder without an unacceptable increase in girth. Optional rings may be positioned over the areas of lesser diameter to prevent collapse. An optional outer sheath also improves longitudinal stability.
