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.

Abstract: An ablation catheter assembly including an elongate catheter body having a proximal portion, a distal portion and a lumen therethrough. A helical structure associated with the catheter distal portion carries a plurality of independently operable electrodes and is transformable between a low-profile configuration wherein a straightening element is positioned in the lumen and an expanded configuration wherein the straightening element is at least partially retracted from the spiral structure. When the helical structure is in the expanded configuration, a laterally offset tip portion extends distally therefrom.

Abstract: Aspects of the disclosure relate to an instrument for pacing, mapping, sensing, and/or ablating cardiac tissue that includes an electrogram filtering circuit. To supply radio frequency energy, the disclosed instruments are only optionally connected to a radio frequency generator. When connected to a generator, the electrogram filtering circuit can be provided in a handle of the instrument, or in a connector, for example, to protect the instrument from potentially high-powered radio frequency energy. Alternatively, various disclosed embodiments are capable of pacing/sensing as a standalone device. The connector can be provided separately from both the instrument and the generator. In some embodiments, the electrogram filtering circuit is adaptive to suit a variety of generators.
