Expandable penile implant

摘要

A penile implant for use in treating erectile impotence includes an elongated flexible rod having a short proximal stem to support the implant and longer distal portion to be implanted in the corpus cavernosum of a penis. A layer of swellable hydrophilic material covers at least part of the distal portion. When the implant is implanted, the hydrophilic layer absorbs water and expands to increase the girth of the penis.
