ELECTRODE CATHETER FOR ABRASION

摘要

PROBLEM TO BE SOLVED: To provide an electrode catheter for abrasion in which speedy and stable abrasion is made possible.

SOLUTION: A wire 21 with an expansion function in a catheter tube 2 is moved back and forth by moving a slider 34 of a hand operating part 31 back and forth. The tops of a plurality of insulated tubes 11 protruded from the top in the catheter tube 2 are moved in the direction of the diameter of the catheter tube 2 and radially or spherically expanded. Electrodes 12 provided on the tops of the respective insulated tubes 11 are equally distributed to a target portion. By uniformly adhering the respective electrodes 12 to the target portion, abrasion can be efficiently performed. A burden to a patient is reduced, and complexity in the manual technique of an operator is reduced.
