Patent ID: 7218958

Claim:
An electrophysiology/ablation lumen catheter comprising: a) an elongated flexible body having a central lumen, a proximal end and at least one electrode disposed adjacent a distal end thereof; b) a catheter deflection assembly disposed in the body; c) an electrical lead connected to each of the electrodes and extending through the body to adjacent the proximal end thereof, the lead adapted for external connection thereof; d) an actuator connected adjacent the proximal end of the catheter deflection assembly and operable upon movement to effect lateral displacement of the distal end; e) an inflatable member operatively extending from an outer surface of the body when inflated; f) a first passage extending through the body within said central lumen and adapted to supply an associated liquid therethrough to the inflatable member; and g) a second passage within said central lumen that communicates with an opening in the body located on the distal end side of the inflatable member, wherein the opening is located inwardly from a terminus of the distal end in a sidewall of said body.
