Device for expanding a stenosis in a body duct

Abstract

Abstract A device is proposed for expanding a stenosis in a body duct, such as an artery, the ureter, the bile duct or the like, which permits an unproblematic, reliable and permanent expansion of a stenosis and is characterised by a part made of a shape-memorising alloy with an outer contour in the form of a cylindrical surface, the part expanding radially at a transition temperature lying above the ambient temperature but below the body temperature, while maintaining a cylindrical outer contour, the diameter at a temperature below the transition temperature being less than that of the vessel. <IMAGE>
