    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.

    摘要: Distal anastomosis devices and associated methodology are described herein. Connector and connector components as well as tools associated therewith are disclosed. The connectors are preferably adapted to produce an end-to-side anastomosis at a graft/coronary artery junction. A fitting alone, or a fitting in combination with a collar may be used as a connector. Each fitting may be deployed by deflecting its shape to provide clearance for a rear segment that rotates about adjoining hinge section(s) so to fit the connector within an aperture formed in a host vessel. Upon return to a substantially relaxed position, a rear segment anchors the fitting it in place. The distal fitting may include additional side features for interfacing with the host vessel/coronary artery. The collar may include features complimentary to those of a fitting and provisions for securing the graft vessel.
