ELECTROSURGICAL CATHETER FOR RESOLVING ATHEROSCLEROTIC PLAQUE

摘要

A method, and device utilized to practice it, for the resolution of tissue by radio frequency sparking. The device of the present invention having a distal end (20) which is insertable within and along the lumen of a tubular body member and manipulated therethrough to desired position where the device will be operated. The device comprises an elongated flexible hollow tube (12) having a distal end, a proximal end and a diameter smaller than the diameter of the tubular body member into which the device is being inserted; a passage (16) within the tube; a plurality of electrodes (14) adjacent the distal end of the device; and circuitry for selectively supplying radio frequency electrical current to at least one of said electrodes.
