Endoprosthesis for insertion into a body vessel

Abstract

Abstract The endoprosthesis is made from at least one wire or strip of an alloy with a shape memory effect, formed into a series of loops (1,2) with parallel sides and rounded ends (5). The loops are joined to form cylindrical sleeves, of which the end ones are more rigid than the others. The alloy wire used to make the endoprosthesis is rectangular or triangular in cross section, with a transverse dimension of the order of 0.20 to 0.50 mm. The sleeves can be made from segments of different lengths. A large-diameter sleeve can be connected to small-diameter sleeves at the confluence of body canals. The endoprosthesis also incorporates a marker for enhanced radio-opacity.
