The endoprosthesis has a braided reinforcing layer (6) made from interconnecting layers (8, 10, 12) of filaments. Each layer has right- and left-handed filaments forming a mesh, with filaments (14) of one layer being interwoven with those of at least one other adjacent layer. The filaments are made from a biocompatible metal such as stainless steel, Phynox, Elgyloy, titanium and its alloys or Nitinol, or a synthetic material which may or may not be assimilated by the organism. The filaments and their layers can be of different thicknesses, from 25 microns upwards, and one endoprosthesis can contain filaments of different types. |
