Percutaneous atrial line ablation catheter

摘要

A percutaneous line ablation catheter is provided for ablating maze- like patterns on the surface of the heart of a patient through line ablation procedure. Typically, the catheter will include an internal electrode at its distal portion that is rendered electrically conductive by ion process deposition of the polymeric material of its shaft with a metallic material or materials. An external electrode typically will be placed on the outside surface of the patient's body, and a conductive circuit connected between the external electrode and the internal electrode to develop an electrical circuit through the patient's body.
