  • Publication number: 20020017306
    Abstract: The invention provides surgical systems and methods for ablating heart tissue within the interior and/or exterior of the heart. A plurality of probes is provided with each probe configured for introduction into the chest for engaging the heart. Each probe includes an elongated shaft having an elongated ablating surface of a predetermined shape. The elongated shaft and the elongated ablating surface of each probe are configured to ablate a portion of the heart. A sealing device affixed to the heart tissue forms a hemostatic seal between the probe and the penetration in the heart to inhibit blood loss therethrough.

  • Patent number: 6314963
    Abstract: The invention provides apparatus and methods for mapping conduction pathways and creating lesions in the heart wall for the treatment of atrial fibrillation. The apparatus may include at least one epicardial ablation probe having a plurality of electrodes for creating a lesion. The apparatus and method facilitate the formation of a lesion which electrically isolates the pulmonary veins from the surrounding myocardium.

  • Patent number: 6237605
    Abstract: The invention provides apparatus and methods for mapping conduction pathways and creating transmural lesions in the heart wall for the treatment of atrial fibrillation. The apparatus may include at least one epicardial ablation probe having a plurality of electrodes for creating a transmural lesion. The apparatus and method facilitate the formation of a transmural lesion which electrically isolates the pulmonary veins from the surrounding myocardium without cutting or penetrating the pericardial reflections.

  • Patent number: 5830214
    Abstract: The invention provides an electrosurgical device (2) and method for cauterizing tissue and evacuating fluid from the surgical site. The device comprises an insulated conductive shaft (4) having a proximal end coupled to an electric generator (40) and a distal end coupled to an electrode (6) for cutting or coagulating tissue. The shaft has an inner lumen (14) fluidly coupled to a vacuum source (50) and a plurality of insulated side holes (8) in communication with the lumen. The side holes are configured to remain free of obstructions so that fluid, such as smoke, can be continuously evacuated during the surgical procedure.
