See full text

A method of producing a catheter includes a step of arranging a lead wire in the lumen of a thermoplastic outer-layer tube such that the lead wire extends in the longitudinal direction of the outer-layer tube; a step of exposing one end of the lead wire out of an opening of the outer-layer tube; a step of joining the one end of the lead wire exposed out of the opening with the inner wall of a ring electrode; a step of covering the opening of the outer-layer tube with the ring electrode; an step of inserting a thermoplastic inner-layer tube in the lumen of the outer-layer tube; and an integrating step of heating the outer-layer tube and the inner-layer tube to integrate the outer-layer and the inner-layer tubes to form an electrode tip such that the lead wire is interlaminarly embedded and fixed between the outer-layer and the inner-layer tubes.
