STENT AND GRAFT WITH STENT

摘要

PROBLEM TO BE SOLVED: To provide a stent and a graft with the stent that can be diametrally easily contracted, have a sufficient expansive force, and reduce an application of a local compressive force to the inwall of a tubular organ even in a case where the stent is set in a curved position of the tubular organ.

SOLUTION: The stent 20 is formed into a cylinder by weaving metal wires 21 and has portions A crosswise intersecting and portions B each curved into a U shape in the net structure of the metal wires 21. The portions B each curved into the U shape are entangled with the crosswise intersecting portions A with the curved tip portions B1 directed outward. By covering the inside periphery and/or the outside periphery of the stent 20 with a cylindrical cover 30, the graft 30 with the stent is formed.
