Abstract: An ablation device for ablating tissue having an outer wall and an inner wall, approximately parallel and concentric with said outer wall, defining an inner fluid chamber and an outer low pressure chamber. Each of the outer wall and the inner wall have an edge defining an open face of the fluid chamber and the low pressure chamber. An ablative element is contained within the fluid chamber. A source of low pressure is coupled to the low pressure chamber. When the edge of the outer wall and the edge of the inner wall contact a surface, the ablation device is at least partially secured to the surface by low pressure created in the low pressure chamber by the source of low pressure. The fluid chamber is at least partially fluidly isolated from the low pressure chamber when the ablation device is at least partially secured to the surface.

Abstract: Embodiments of the invention provide an ablation apparatus for ablating target tissue adjacent pulmonary veins of a patient. The ablation apparatus can include a tube capable of being advanced around the pulmonary veins to form a loop. The tube can receive or include electrodes to ablate target tissue. Some embodiments provide a loop ablation device, which may include a cannula and two or more electrode rods carrying two or more bipolar electrodes. The electrode rods can be advanced through the distal ends toward the proximal ends of the loop and toward the target tissue. The bipolar electrodes can receive energy to ablate the target tissue. The bipolar electrodes may be surrounded by the liquid within the cannula while ablating the target tissue. The loop ablation device can further include a rotating grasping mechanism coupled to the electrode rods.

Abstract: Some embodiments of the invention provide a system for occluding a left atrial appendage of a patient. Some embodiments of the system can include a ring occluder that can be positioned around the left atrial appendage and a ring applicator to position the ring occluder with respect to the left atrial appendage. Other embodiments of the invention provide a clip occluder that can be positioned around the left atrial appendage. A clip applicator can position the clip occluder with respect to the left atrial appendage.

Abstract: The present invention generally relates to an improved implantable medical device (IMD) and more particularly to an ultrasonically weld perforated lid for an IMD to form a hermetic seal between the IMD and the perforated lid. Appropriately configured perforated lids retain one or more components within a cavity or port formed in a part of an IMD. Such lids preferably secure a pierceable resilient grommet, septum or other resilient member in a cavity or port. When an adjustment instrument, a pull tool or a syringe is temporarily inserted therethrough and later extracted, the resilient member heals (i.e., seals and/or reseals). Preferably, the resilient member abuts a mechanical stop and is compressed slightly during assembly and ultrasonic welding of the lid. The resilient member preferably has a lateral dimension like the cavity or port so that when the lid compresses the resilient member it expands slightly and contacts the interior cavity surfaces thus improving the seal.

Abstract translation: 本发明总体上涉及一种改进的可植入医疗装置（IMD），更具体地涉及用于IMD的超声波焊接穿孔盖，以在IMD和多孔盖之间形成气密封。 适当配置的穿孔盖在IMD的一部分中形成的腔或端口内保留一个或多个组件。 这种盖子优选地将可刺破的弹性垫圈，隔膜或其它弹性构件固定在空腔或端口中。 当调节工具，拉拽工具或注射器临时插入其中并随后抽出时，弹性部件愈合（即，密封和/或回收）。 优选地，弹性构件邻接机械止动件并且在盖的组装和超声波焊接期间被稍微压缩。 优选地，弹性构件具有像空腔或端口的侧向尺寸，使得当盖子压缩弹性构件时，其稍微膨胀并与内腔表面接触，从而改善密封。
