<P>PROBLEM TO BE SOLVED: To provide an electric catheter capable of compatibly attaining enhancement of push-in property when inserting into an affected site, enhancement of flexibility of a catheter during using, and enhancement of cooling capability near an electrode. <P>SOLUTION: The electric catheter includes a catheter tube in which a lumen 6a is formed, a first electrode 11 which is attached to the distal end part of the catheter tube 6, a second electrode 13 which is arranged apart from the first electrode 11 by a predetermined distance in the longitudinal direction, a handle 4 to which the proximal end part of the catheter tube 6 is connected, a stylet 7 which is detachably inserted along the lumen 6a over the length from the first electrode 11 to the handle 4 and is attached and detached from the proximal end of the handle 4, a supply tube 8 in which a supply channel for flowing cooling fluid is formed and a distal end opening part 8b of the supply channel opens in the inner space 11a of the first electrode 11. The distal end 7b of the stylet 7 is detachably attached to an attaching part 11d communicating with the inner space 11a of the first electrode 11. <P>COPYRIGHT: (C)2011,JPO&INPIT |
