Beschreibung
Zusammenfassung:	A stent 51c is formed by braiding a plurality of filament threads containing a biodegradable polymer into a cylindrical braid, and connecting points 53a-53d at end portions of the filament threads constituting the braid are arranged in two or more rows in a length direction of the braid. Elastic threads 54a-54d are each disposed outside at least a part of the stent 51c and along at least a part of the stent in the length direction including the vicinity of either one of end portions of the stent. One end of each elastic thread is fixed to the vicinity of the end portion of the stent, and the other end is fixed to any portion of the stent. In a state in which the stent is radially contracted, tension may be applied to the elastic threads. Thus, provided are a stent that is easy to load into a delivery system and also facilitates the expanding operation, as well as a medical device including the stent.
