ENDOCARDIAL MAPPING AND ABLATION SYSTEM UTILIZING A SEPARATELY CONTROLLED ABLATION CATHETER AND METHOD

摘要

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