Abstract
A steerable first catheter directs the introduction of a guide sheath, which can otherwise be free of any onboard steering mechanism. The guide sheath, in turn, directs the introduction of the electrode-carrying second catheter, 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 electrode-carrying catheter results in a significant reduction in the overall size of the system components.
