Abstract
A method and system for removing body vessels from a patient is provided. An embodiment of the method includes a method for harvesting a vessel for subsequent use in a grafting procedure, such as, for example, saphenous vein graft harvesting for a coronary bypass surgical operation. A quantity of a solution is infused into tissue surrounding the portion of the vessel to be removed. An external device is used to apply an energy field to the tissue to loosen the intercellular connections between the tissue and the vessel to be removed. One such device is an ultrasonic instrument having an ultrasonic transducer comprised of a composite of ultrasonic crystal transducers. Once the energy field has been applied, the portion of the vessel to be removed is separated from surrounding tissue and tributary vessels are ligated. The portion of the vessel is then transected and removed from the body.
