Abstract

A medical long object of the present invention has a part made of a polymeric material containing a laser color developing agent at least in a part of the surface thereof, and a light developing portion formed in the part by color development of the laser color developing agent due to irradiation with laser light.

What is claimed is:  
     
         1 . A medical long object comprising a part formed of a polymeric material containing a laser color developing agent at least in a part of a surface, and a color developing portion formed in the part by color development of the laser color developing agent due to irradiation with laser light.  
     
     
         2 . A medical long object having a tip end portion and a base end portion, comprising a polymeric material surface formed of a polymeric material containing a laser color developing agent at least in the tip end portion, and a color developing portion formed by color development of the laser color developing agent due to irradiation with laser light on the polymeric material surface.  
     
     
         3 . A medical long object according to  claim 1 , wherein the laser color developing agent contains mica and/or a compound thereof.  
     
     
         4 . A medical long object according to  claim 1 , which is a guide wire.  
     
     
         5 . A medical long object according to  claim 1 , which is a catheter.  
     
     
         6 . A method for producing a medical long object, comprising: 
 forming at least a part of a surface of a medical long object with a polymeric material containing a laser color developing agent; and    irradiating only a portion of the surface of the medical long object in which a color is to be developed with laser light so as to allow the laser color developing agent to develop a color, thereby forming any pattern on the surface of the medical long object.    
     
     
         7 . A method for producing a medical long object according to  claim 6 , wherein the laser color developing agent is contained 0.01 to 10% by mass on the total amount of the polymeric material component.
