Abstract
The invention relates to an apparatus for widening a stenosis in an elongated body cavity such as an artery, the urethra, the ureter, a bile duct or the like, characterized by an endoprosthesis made from a memory alloy with a substantially cylindrical jacket-like outer contour with a lock surrounding and radially holding together the endoprosthesis and with an applicator for the endoprosthesis. It is important that the apparatus is supplied in such a way that in the delivery pack the endoprosthesis is held radially from the outside in its compressed (low temperature) position, which is ensured by the above-described construction of the apparatus according to the invention.
