Abstract
Disclosed herein is a medical wire with an intracorporeally indwelling member connected to the leading end part of a conductive wire body through a thermally-fusible connecting member, wherein expected heat generation can be achieved even when a conductive member that causes leak comes into contact with the leading end part of the conductive wire body, and thus the intracorporeally indwelling member can be surely released.This medical wire comprises a conductive wire body and an intracorporeally indwelling member connected to the leading end part of the conductive wire body through a thermally-fusible connecting member, in which the connecting member is 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.
