Kind Code:
A1
Abstract:
Provided is a stent 51C made of a cylindrical braid formed from a plurality of filament yarns containing a biodegradable polymer, wherein connecting points 53a-53d are formed at the ends of the filament yarns constituting the braid so as to be aligned in two or more rows in the longitudinal direction of the braid. Elastic yarns 54a-54d are disposed outside at least a part of the stent 51C and at least a longitudinal part, of the elastic yarns, that includes the vicinity of the ends thereof. One end of each of the elastic yarns is fixed in the vicinity of a stent end, while the other end is fixed at any position in the stent. When the diameter of the stent is contracted, tension may be applied to the elastic yarns. Accordingly, provided are: a stent that is easy to mount to a delivery system and enables an easy expansion operation; and a medical device including this stent.
