<P>PROBLEM TO BE SOLVED: To provide an electrode catheter, in which sharp potential with few noise can be measured by an electrode even though the electrode is excellent in imaging characteristics (visibility by an X-ray image etc.) in use. <P>SOLUTION: The electrode catheter includes a catheter body, a control handle, a catheter tip end part 30 in a double tube structure composed of an inner tube 31 and an outer tube 32, a plurality of metallic rings 41 arranged by being respectively separated in the axial direction in a state interposed between the inner tube 31 and the outer tube 32, and a plurality of lead wires 61. On the tube wall of the outer tube 32 constituting the tip end part 30 of the catheter, opening windows 321 are formed corresponding to positions where the metallic rings 41 are fixed, and electrodes 41A are configured by a part of the outer periphery surface of the exposed metallic rings 41. <P>COPYRIGHT: (C)2012,JPO&INPIT |
