Hemodynamic luminal endoprosthesis

A multilayer luminal braided self-expanding stent for an anatomical conduit, expandable from a reduced diameter to a nominal diameter, comprising a cylindrical outer braided peripheral stent structure comprising a layer wherein

• said outer peripheral stent structure is permanently linked by at least a pair of filaments to a cylindrical central hollow braided core comprising a layer capable of acting as an inner braided hemodynamic flow deflector;
• said outer peripheral stent structure, said central hollow braided core and said at least a pair of filaments constitute a commonly braided metal structure, a gap of between 10 to 90% of the nominal diameter of the outer stent structure extends between the central braided core and the outer stent structure of the commonly braided structure, wherein said outer peripheral stent structure and said central braided core of the commonly braided structure are permanently linked and extend parallel to each other along their respective full lengths.
