To provide a new balloon catheter enabling formation of, with high dimensional accuracy and excellent shape adaptability with respect to a balloon, an additional structure such as a blade and a reinforcement member to be additionally provided to the balloon. In this balloon catheterprovided with an expandable/contractible balloonon the distal end side of a catheter, an additional structurehaving a prescribed pattern is formed through electroforming or the like directly onto an inner circumferential surfaceand/or an outer circumferential surfaceof the balloon

Method of manufacturing a balloon catheter

A stent () configured to be placed in a body lumen and having a tubular shape formed by a structure that is expandable and contractible skeleton () in a radial direction, the skeleton () having a heteromorphic structure due to changes of a cross section shape thereof in a thickness direction. A stent () that is expandable and contractible in the radial direction while being configured to be placed in a body lumen, the stent () having a heteromorphic tubular shape, a cross section shape of which changes in a lengthwise direction, and having a metal skeleton () formed by at least one of electroforming and etching.
