  • Patent number: 7041095
    Abstract: A medical device, and related method, use epicardial ablators and detectors for intraoperative epicardial approaches to ablation therapy of cardiac conduction pathways. An epicardial gripper is sized to grasp the cardiac circumference or smaller structures on the epicardial surface of the heart. Ablators are disposed on the arms of the gripper for epicardial ablation of cardiac conduction tissue. In another embodiment of the invention, an electrode system includes a flexible, adjustable probe forming a loop for epicardial ablation. Ablators are provided on one or multiple surfaces of the probe for epicardial ablation of cardiac conduction tissue. In yet another embodiment of the invention, an endocardial ablator detection system provides an indicator adjacent an ablator on an endocardial catheter, and a detector on an epicardial probe.

  • Patent number: 6916317
    Abstract: A method of treating cardiac arrhythmia, including guiding a distal end portion of a catheter, the distal end portion having a distal tip and accommodating an elongated configuration of ablation electrodes, from the inferior vena cava into the right atrium of a human heart, guiding the distal end portion from the right atrium into the right ventricle of the heart, deflecting the distal tip into a hook configuration, pulling the catheter towards the inferior vena cava until the hook configuration engages the tricuspid annulus of the heart and the configuration of electrodes engages the isthmus of tissue between the tricuspid annulus and the inferior vena cava of the heart, and activating the configuration of electrodes to produce a substantially continuous lesion on the isthmus of tissue.

  • Patent number: 6677028
    Abstract: Retroreflective articles having multilayer films are useful for commercial graphics and retroreflective products, such as roll-up signs for highway transportation safety. The articles comprise multilayer films having at least one layer of polyurethane and at least one layer of a copolymer of alkylene and at least one non-acidic, polar co-monomer. Articles having the new multilayer films provide the same or improved performance, are less expensive, and offer improved methods for manufacturing, when compared to prior articles.

  • Patent number: 6113584
    Abstract: A method and system for lysing a patient's heart tissue causing or involved with arrhythmia which includes an intravascular catheter with a relatively inelastic occlusion balloon on the distal end of the catheter which is inflated to block an artery or vein of the patient's heart so than when lysing fluid such as an ethanol solution is discharged from the distal port in the catheter the inflated balloon prevents the proximal refluxing of lysing medium into undesirable areas of the patient's heart. The inelastic balloon is configured to be inflated to a diameter of about 0.7 to about 1.3, preferably about 0.8 to about 1.2, times the diameter of the blood vessel in which the balloon is to be inflated so as to effectively occlude the passageway without damaging the wall of the blood vessel. The working length of the balloon is less than about 1.5 cm, preferably less than 0.75 cm.
