ELECTRODE CATHETER

摘要

An electrode catheter, comprising at least one electrode (1) fixed to the distal end side, and a catheter tube (2) bonded to the electrode (1) and extending from the distal end side to the proximal side, is further provided with a guide wire lumen (3) extending from the distal end side to the proximal side, and a conductor (4) for transmitting an electric signal or electric energy between the electrode (1) and the proximal side, characterized in that the outside diameter of the catheter tube (2) is 1.3 mm or less, and flexural rigidity in the region 5-40 cm from the distal end is 2N or less. The electrode catheter is characterized in that an electrode can be easily arranged at the target part of a peripheral vessel such as a cerebral blood vessel and coronary arteries bending three-dimensionally with a small curvature, and thereby inspection and treatment can be performed exactly.
