Self-expanding stent for hollow organs

摘要

The stent is for the expansion and/or holding open of a hollow organ, and is formed as a tubular, self-expanding net, which in the collapsed state is stretched in the axial direction (13) and is shortened in the axial direction in the expanded state. The filaments (11) comprising the stent have a rectangular cross-section, and at the crossing points (12) of the stent (10) are completely coated in plastics, in order to form a fixed link at the crossing point. Between the filaments free spaces (16) are formed. The net is constructed from wire filaments, partic. metal, which are coated in a rubber-elastic plastics material. The filaments are interwoven against a basic bending to form a tubular net.
