    • An embodiment of the invention includes a surgical device for coagulating soil tissue such as atrial tissue in the treatment of atrial fibrillation, atrial flutter, and atrial tachycardia. The surgical device can include at least one elongate member comprising conductive elements adapted to coagulate soft tissue when radiofrequency or direct current energy is transmitted to the conductive elements. Openings through said conductive elements are routed through lumens in the elongate member to a vacuum source to actively engage the soft tissue surface intended to coagulate into intimate contact with the conductive elements to facilitate the coagulation process and ensure the lesions created are consistent, contiguous, and transmural. The embodiments of the invention can also incorporate cooling openings positioned near the conductive elements and coupled with a vacuum source or an injection source to transport fluid though the cooling openings causing the soft tissue surface to cool thus pushing the maximum temperature deeper into tissue. The embodiments of the invention can also incorporate features to tunnel between anatomic structures or dissect around the desired tissue surface to coagulate thereby enabling less invasive positioning of the soft tissue coagulating device and ensuring reliable and consistent heating of the soft tissue.

    • 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.
    • 本发明的一个实施例包括用于在治疗心房颤动,心房扑动和心房心动过速中凝固软组织例如心房组织的手术装置; 腱或韧带收缩; 或关节软骨清除。 手术装置将抽吸机构与凝固机构相结合,改善了装置的病变创造能力。 手术装置包括细长构件,其具有绝缘覆盖物,该绝缘覆盖物围绕能够在射频或直流能量传递到导电元件时使软组织凝结的导电元件附近。 穿过绝缘覆盖物的开口暴露导电元件的区域,并且连接到被延伸到真空源的细长构件中的腔。 抽吸使得软组织积极地接合开口,从而使整合的暴露的导电元件有助于凝固过程,并确保所产生的损伤是一致的,连续的和透壁的。 本发明的实施例还可以包括与导电元件相关联的冷却机构并且耦合到流体源,以沿被接触的软组织表面被动地输送流体,从而将最大温度推向组织。
