Abstract
An electrode catheter includes a metal inner tube with distal and proximal ends and an outer tube formed of a synthetic resin so as to cover the outside surface of the inner tube. The inner tube has a helical slit formed from the distal end to a predetermined position, and one or more insulated wires are laid inside the inner tube from the proximal end to the distal end portion. One or more electrodes are disposed on the outer tube, with the wires extending out of the inner tube through the slit and connected to the electrodes. This electrode catheter possesses high pushability and torque-transmission capability along with a high flexibility and kink resistance, and can be easily inserted into a desired position of complexly branched thin blood vessels without kink or breakage of the wires caused by collapse of the lumen.
