Abstract

Method for implanting and subsequently removing mechanical implants of an Ni-Ti or a Ti-Nb alloy material which exhibits the memory effect which occurs due to heating of the implant to a temperature above the specific temperature for the alloy material. The memory effect is actuated by heating the implant after implantation of same in the living tissue, and upon completion of the healing process, the implant is substantially returned to its shape upon implantation by cooling it to a temperature below the temperature which actuates the opposite memory effect to facilitate removal.
