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 comprise 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 to introduce 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 is capable of regulating the flow of conductive media through the conductive media outlet openings to form a reasonably consistent flow of the conductive media through substantially all of the conductive media outlet openings.
