Stent for treating arteriosclerosis is made of magnetic alloy with specified permeability and Curie temperature, for self-controlled, limited induction heating to prevent re-stenosis

摘要

The stent is made of an alloy with relative magnetic permeability exceeding 100. Its Curie temperature is close to a limiting temperature. The alloy and hence the limiting temperature, are selected to prevent or treat further in-stent re-stenosis. Above this temperature, vessel damage commences. An Independent claim is also included for the induction heating equipment which is used with the stent.
