ABSTRACT:
An apparatus and method for a catheter guide wire having a helical coil encasing or covering at least a portion of the distal end section of the wire. At least one region of the distal end is heat treated to facilitate bending or forming a J-tip. The treated regions are of a size to cover only a small portion of the distal end section of the wire, thus preserving the resilience and flexibility of the tip for steerage through a lumen of a body. This improved method and device enables the bending or forming of the guide wire tip with comparative ease with regard to non-treated tips, without sacrificing tip performance as often occurs when the entire or major portion of the distal tip is heat treated, or bent without treatment simply by force.
