Abstract

Instrument and systems for applying ablative energy to epicardial tissue via a subxiphoid access surgical approach. The instrument has a head assembly sized and shaped for a subxiphoid surgical approach to a patient's heart and defines a contact face. The head assembly includes a paddle body, a first ablation electrode, and a second ablation electrode. The ablation electrodes are coupled to the paddle body in a spaced apart, spatially-fixed fashion. The ablation electrodes are exteriorly exposed at the contact face. A tubular member extends from the head assembly and maintains wiring connected to the ablation electrodes. The instrument is manipulable to locate the contact face on epicardial tissue of a patient's heart via a subxiphoid surgical approach, such as between the left and right pulmonary vein junctions of the posterior left atrium.
