Abstract:
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.
