Medical guide wire

Abstract

A medical guide wire which can have both slidability and operability and can be easily manufactured is provided. A medical guide wire ( 1 ) includes a long flexible wire body ( 2 ), and a wire-like material structure ( 3 ) including a wire-like material ( 31 ) arranged on the surface of the wire body ( 2 ), in which the wire-like material structure ( 3 ) is thermally fused onto the wire body ( 2 ).

1 . A medical guide wire comprising:
 a long flexible wire body; and   a wire-like material structure including a wire-like material arranged on the surface of the wire body,   wherein the wire-like material structure is thermally fused onto the wire body.   
     
     
         2 . The medical guide wire according to  claim 1 , wherein the wire-like material structure includes a thermally-fused portion on the wire body, the thermally-fused portion including a narrow portion narrower than the maximum width of the wire-like material of the wire-like material structure before thermal fusing. 
     
     
         3 . The medical guide wire according to  claim 1  or  2 , wherein the wire-like material structure includes the wire-like material helically wound on the wire body. 
     
     
         4 . The medical guide wire according to  claim 1  or  2 , wherein the wire-like material structure has meshes. 
     
     
         5 . The medical guide wire according to any one of  claims 1  to  4 , wherein the wire-like material has a non-circular cross section. 
     
     
         6 . The medical guide wire according to any one of  claims 1  to  5 ,
 wherein the wire body is made of a conductive material, 
 wherein the wire-like material is formed of a material having lower magnetic properties than the wire body, 
 wherein the wire-like material structure is thermally fused onto the wire body in such a way that the wire body is heated by electromagnetic induction from the outside of the wire-like material structure arranged on the wire body, and heat from the heated wire body melts at least one of the opposed regions of the wire-like material structure and the wire body.
