Stent

Abstract

The invention relates to a stent for transluminal implantation in hollow organs, in particular in blood vessels, ureters, esophagi, colons, duodena, or bile ducts, comprising a substantially tubular body, which can be transferred from a compressed state having a first cross-sectional diameter into an expanded state having an enlarged second cross-sectional diameter, wherein the stent comprises a plurality of cells, which are defined by bordering elements formed by the tubular body. The stent is distinguished in that some of the cells are extended in the longitudinal direction of the stent in comparison with the remaining cells in order to form a slanted end face of the stent.

1 . A method of manufacturing a stent, in which
 a) the stent is cut out of a tubular material;   b) the stent is widened up to its expanded state, and   c) a shape of cells of the stent is changed and fixed in the expanded state.   
     
     
         2 . The method in accordance with  claim 1 ,
 wherein a core is used for the widening to which fastening means are attached to change and to fix the shape of the cells of the stent.   
     
     
         3 . The method in accordance with  claim 1 ,
 wherein the fastening means are needles or mandrels that are introduced into holes of the core.   
     
     
         4 . The method in accordance with  claim 1 ,
 further comprising the step of   d) permanently fixing by means of a heating process the shape of the cells of the stent that is changed.
