Abstract: A steerable first catheter (14) directs the introduction of a guide sheath (16), which can otherwise be free of any onboard steering mechanism. The guide sheath (16), in turn, directs the introduction of an electrode carrying second catheter (18), which can likewise be free of any onboard steering mechanism. Use of a guide sheath positioned by a separate, dedicated steering catheter to guide a separate, dedicated steering electrode carrying catheter results in a significant reduction in the overall size of the system components.
