    Abstract: 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 catheter 10 provided with an expandable/contractible balloon 14 on the distal end side of a catheter 12, an additional structure 36 having a prescribed pattern is formed through electroforming or the like directly onto an inner circumferential surface 34 and/or an outer circumferential surface 82 of the balloon 14.

    Abstract: A stent (32) configured to be placed in a body lumen and having a tubular shape formed by a structure that is expandable and contractible skeleton (18, 19) in a radial direction, the skeleton (18, 19) having a heteromorphic structure due to changes of a cross section shape thereof in a thickness direction. A stent (10) that is expandable and contractible in the radial direction while being configured to be placed in a body lumen, the stent (10) having a heteromorphic tubular shape, a cross section shape of which changes in a lengthwise direction, and having a metal skeleton (18, 19) formed by at least one of electroforming and etching.

    Abstract: Provided is a guide wire having a novel structure, with which it is possible to improve production efficiency and to effectively prevent large irregularities from forming on an outer circumferential surface of a core wire. Further provided is a guide wire having a novel structure, with which it is possible to more meticulously set bending rigidity to a distal end portion thereof. In a guide wire having a coil externally mounted about a distal end portion of a core wire, a proximal end portion of the coil is integrally joined to the core wire during formation of the coil. Furthermore, in a guide wire having a coil externally mounted about a distal end portion of a core wire, a cross-sectional shape of a wire that constitutes the coil varies in a lengthwise direction of the coil.
