Abstract:
An ablation catheter comprising(a) a catheter body with proximal and distal ends and an external surface,(b) a lumen within the catheter body,(c) a plurality of conductive media outlet openings in the external surface of the catheter body which are in communication with the lumen, wherein the conductive media outlet openings form a linear line of openings extended down the catheter body,(d) an electrode fixedly secured to the catheter body and located within the lumen,(e) an introduction system for introducing a conductive media into the lumen to contact the electrode, and(f) a conductive media flow control system structured to expel the conductive media through the conductive media outlet openings wherein the conductive media flow control system comprises a plurality of electrode coils, wherein a gap between individual electrode coils varies.
