SMALL LOOP ABLATION CATHETER

摘要

A catheter system for creating lesions for the treatment of cardiac arrhythmias is disclosed that includes a catheter having a distal ablation segment that has an electrode array comprising a plurality of spaced ablation and recording electrode devices arranged in a tight loop configuration that is used to create a series of overlapping loop-shaped ablation footprints to produce a continuous lesion resembling a chain-link configuration.
