Abstract:
1. A medical wire comprising: a conductive wire body, and an intracorporeally indwelling member connected to a leading end part of the conductive wire body through a thermally-fusible connecting member, wherein the connecting member is adapted to be heated and fused by supplying an electric current for fusion through the conductive wire body, thereby releasing the intracorporeally indwelling member, wherein a non-conductive coating film is formed on an external peripheral surface of an electrode-forming portion in the leading end part of the wire body, and a part of the surface of the wire body is exposed through the coating film, thereby forming a heating electrode portion, wherein the heating electrode portion is formed by a plurality of fine cutout portions formed in the coating film, wherein the intracorporeally indwelling member is formed by a coil material comprising a coiled metal filament, and a maximum width of the cutout portions is less than an outer diameter of the coil material forming the intracorporeally indwelling member, wherein the cutout portions are adapted to assist fusing of the thermally-fusible connecting member, and wherein the exposed part of the surface of the wire body is adapted to come into contact with body fluid.
