Induction heater system for shape memory medical implants and method of activating shape memory medical implants within the mammalian body

摘要

A method of altering a medical implant having a shape memory portion includes the use of a probe having a tip provided with an induction coil. The induction coil is electrically coupled to an induction power supply. The induction coil is inserted into the mammalian body. The power supply is activated at a suitable frequency to cause the induction coil to generate a magnetic field, wherein such magnetic field induces eddy currents in the shape memory portion of the implant which are sufficient to heat the shape memory portion of the implant to a phase transformation temperature to effect shape change of the implant.
