"Le's solution is a heat-activated exoskeleton of nitinol, a metal known for its superelastic properties and already in use in medical devices used for endovascular surgery. In this case, the urologist could do a simplified operation to insert the nitinol implant, which remains flaccid at body temperature but can "remember" an expanded shape and return to that shape when heated. Le and collaborators at Southern Illinois University are currently working on a remote-control device that can be waved over the penis, using induction to heat the NiTi a few degrees above body temperature and ratcheting open the alloy prosthesis to expand the penis in length and girth."
