ABSTRACT:
A temporary stent comprises a coil of tubular thermoplastic material and a heating element inside the tubular material, or a film with a metal film resistive heating element coated thereon. A method of temporarily supporting the wall of a vessel comprises the steps of inserting a thermoplastic body having a first outer dimension less than the inside dimension of the vessel into the vessel to the desired support position; heating the thermoplastic above its softening transition temperature and expanding it to a second outer dimension larger than its first outer dimension; cooling the thermoplastic body to below its softening transition temperature while at its second outer dimension; allowing the cooled thermoplastic body to temporarily support the vessel; heating the thermoplastic above its softening transition temperature to soften the thermoplastic; and removing the softened thermoplastic body from the vessel.
