Endocardial mapping and ablation system utilising a separately controlled ablation catheter and method.

摘要

Endocardial mapping ablation system (11) for introduction into a chamber of a heart formed by a wall and having a passage leading thereto. The system (11) is comprised of a catheter probe (12) having a distal extremity (18). A plurality of electrodes (26) are carried by the distal extremity (18) for mapping the wall of the chamber. An ablation catheter (13) is provided having a distal extremity (54). The ablation catheter (13) has control means whereby the distal extremity (54) can be bent separately of movement of the catheter probe (12) to come into close proximity to the wall of the heart. The distal extremity (54) of the ablation catheter (13) is provided with capabilities for ablating a portion of the wall of the heart to eliminate an arrhythmia in the heart.
