摘要： 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.

摘要： Guide catheter exchange device and method of exchanging a guide catheter. The guide catheter exchange device includes a magnetically responsive segment located on a proximal end for maintaining a previously placed guide wire in position across a stenosis, while performing a guide catheter exchange procedure. The guide catheter exchange device allows a guide catheter exchange procedure to be performed by a solo physician.

摘要： An apparatus and method for performing diagnostics and intravascular therapies. A guidewire anemometer can be used to measure the velocity of fluid flowing through the vasculature. An in-line anemometer can be used to measure the volumetric flow rate of fluid transported out of a patient's body. A heated balloon catheter can be used to deliver heat therapy no a vessel wall in a patient's vasculature.
