STENT
Document Type and Number:
WIPO Patent Application WO/2011/021654
Kind Code:
A1
Abstract:
A stent is configured in such a manner that, when rolled in a tubular shape in order to be mounted to a catheter, the stent has no protrusion on the outer periphery thereof and the loop has a substantially perfect circle shape and not a water drop shape. As a result, the stent does not damage the inner wall of a blood vessel when delivered to an affected site within the blood vessel and does not cause irritation and excessive thickening due to stress. A stent (1) is provided with ring forming sections (10) which consist of a film-like material and are connected to each other by connecting sections (11) so as to be arranged side by side with required spacings provided therebetween. The ring forming sections (10) are each provided with an insertion opening (13) which is provided to one end side of the ring forming section (10), a latch section (14) which is provided to the other end side and is passed through the insertion opening (13) from the curved inner surface side to the outer surface side, and latch engagement sections (170) which are configured in such a manner that, after the latch section (14) side has been passed through the insertion opening (13) to form the ring forming section (10) into a ring-like shape and then has been engaged by being passed through to the curved inner surface side, the engagement position of the latch section (14) is movable only in one direction which is the direction in which the diameter of the ring forming section increases.
