MULTI-ELECTRODE BALLOON CATHETER WITH CIRCUMFERENTIAL AND POINT ELECTRODES

摘要

A catheter has a balloon electrode assembly with at least one compliant balloon member and at least one electrode carried on an outer surface of the balloon member for accomplishing circumferential sensing or ablation in a tubular region of the heart, including a pulmonary vein or ostium. The catheter may also include an electrode assembly with a tip and/or ring electrode distal of the balloon electrode assembly adapted for focal contact.

主权项

1. A catheter comprising:
an elongated catheter body having proximal and distal ends; a first assembly distal of the catheter body, the first assembly having at least one balloon member with an outer surface, and at least one electrode on the outer surface; a tubing extending through the catheter body, the tubing defining a lumen adapted to pass fluid into the at least one balloon member to expand the at least one balloon member; and a second assembly distal of the first assembly, the second assembly having at least one electrode.
