Title:
STENT AND STENT GRAFT
Document Type and Number:
WIPO Patent Application WO/2016/203851
Kind Code:
A1
Abstract:
[Problem] To expand and fix a stent 1 at a target indwelling site, and thereafter prevent damage to the wall of a blood vessel of an affected site by arranging the stent so that a hook 6 does not protrude out of a terminal end-side annular unit 4DE of the stent 1, or even when protruding out, the hook does not come into contact with the wall of the blood vessel. [Solution] The hook 6 has a terminal end section 6DE and a proximal end section 6PE. The terminal end section 6DE has a substantially curved or substantially rectilinear shape. The proximal end section 6PE has two substantially straight lines 6ST. Proximal end sides of the two substantially straight lines 6ST are fixed by a fixing means 3 across two or more mountain sections M to midway on a strut 4STS3 linked to a mountain section MS3 in one direction of a side section S and midway on a strut 4STS4 linked to a mountain section MS4 in one direction of another side section S. When the stent 1 is released from a sheath 10, the hook 6 is separated from a groove 2M of a distal end tip 2, and is drawn into the terminal end-side annular unit 4DE.
