Abstract:
1. An ablation catheter comprising: a catheter having a distal end adapted for insertion into the left atrium of patient through the Fossa ovalis; an electrode array comprising at least one resilient arm, each arm having a proximal arm segment and a distal arm segment extending distally from an outer end of the proximal arm toward the center line of the catheter, such that the proximal arm segment extends from a longitudinal axis of the catheter such that a proximal portion of the proximal arm segment forms an acute angle with the longitudinal axis of the catheter; a plurality of electrodes disposed on each of the proximal arm segments of the array; wherein the proximal arms are arcuate, and extend outwardly and proximally and then curve distally such that the arcuate shape of the proximal arms is configured to, in use, substantially conform and ablate a septal wall.
