    摘要: A method for percutaneous dissection of a segment of vascular tissue from a patient is provided which includes providing an elongated tubular member having a proximal end and a distal end, and blunt dissection structure positioned adjacent the distal end of the tubular member and remotely actuable from adjacent the proximal end of the tubular member. The method further provides for percutaneously accessing a first end portion of the vascular tissue segment, the blunt dissection structure is positioned adjacent the vascular tissue segment and is actuated to bluntly dissect the vascular tissue segment from surrounding body tissue.

    摘要: An ultrasonic dissection and coagulation system for surgical use is provided. The system includes an ultrasonic instrument, a control module, and a pedal actuator. The ultrasonic actuator has a housing and an elongated body portion extending from the housing. An ultrasonic transducer supported within the housing is operatively connected to a cutting blade by a vibration coupler. The vibration coupler conducts high frequency vibration from the ultrasonic transducer to the cutting blade. The cutting blade has a cutting surface which is angled with respect to the longitudinal axis of the elongated body portion and, thus, with respect to the axis of vibration. A clamp member having a tissue contact surface is positioned adjacent to the blade member and is movable from an open position in which the tissue contact surface is spaced form the cutting surface to a clamped position in which the tissue contact surface is in close juxtaposed alignment with the cutting surface to clamp tissue therebetween. The clamp member and the angled blade combine to enhance contact between tissue and the cutting surface of the blade member.
