US Patent 7632289 Harvester

A device for removing and harvesting veins that minimizes the invasive nature of the procedure by providing an internal cutting device with an inner blade to sever the vein at the desired location from below the skin surface, after separation of the vein from the surrounding tissue. The device also includes a serrated cutting tip, a cutting system having a looped wire or two or more wires connected at the distal end of the device, which can be tightened to sever the vein in lieu of the use of the inner blade, or heated by a power source to cauterize the vein. An injection port and cannula may also be contained in the device for delivery of local anesthesia around the vein.
