    摘要： Devices and methods are provided for creating lesions in endocardial tissues surrounding a vessel opening to thereby isolate focal arrhythmia substrates, including an invasive catheter assembly comprising an elongate body having a longitudinal axis and first and second lumens, a first catheter having a distally mounted expandable anchor body disposed in the first lumen, and a second catheter having a distally mounted electrode disposed in the second lumen, the elongate body having a first distal opening accessing the first lumen through which the first catheter may be extended axially relative to the longitudinal axis of the elongate body and a second distal opening accessing the second lumen through which the second catheter may be extended at an angle relative to the longitudinal axis of the elongate body. The disclosed invention also includes an elongate catheter having an expandable electrode body mounted on one end, wherein the electrode body is configured to form an enlarged circumferential region when expanded, the enlarged circumferential region defining a distal facing surface of the electrode body, the distal facing surface including an area configured to emit radio frequency (RF) energy.

    摘要： Surgical systems for less invasive access to and isolation of an atrial appendage are provided. A suturing grasper compresses soft tissue structures and deploys one or more sutures through complimentary pledget(s) carried by the grasper. The pledgets are reinforced, containing support members that define the profile of the stitch and distribute stresses applied by the stitch, once tightened, over a length of tissue. This hardware may be applicable to other surgical and catheter based applications as well including: compressing soft tissue structures lung resections and volume reductions; gastric procedures associated with reduction in volume, aneurysm repair, vessel ligation, or other procedure involving isolation of, resection of, and reduction of anatomic structures.

    摘要： An embodiment of the invention includes a surgical device for coagulating soft tissue such as atrial tissue in the treatment of atrial fibrillation, atrial flutter, and atrial tachycardia; tendon or ligament shrinkage; or articular cartilage removal. The surgical device integrates a suction mechanism with the coagulation mechanism improving the lesion creation capabilities of the device. The surgical device comprises an elongate member having an insulative covering attached about conductive elements capable of coagulating soft tissue when radiofrequency or direct current energy is transmitted to the conductive elements. Openings through the insulative covering expose regions of the conductive elements and are coupled to lumens in the elongate member which are routed to a vacuum source. Suction causes the soft tissue to actively engage the opening thus the integrated, exposed conductive elements to facilitate the coagulation process and ensure the lesions created are consistent, continuous, and transmural. The embodiments of the invention can also incorporate cooling mechanisms associated with the conductive elements and coupled to a fluid source to passively transport fluid along the contacted soft tissue surface to cool thus pushing the maximum temperature deeper into tissue.
