ABSTRACT:
An arterial bypass tool for use in inserting and positioning a bypass artery alongside an occluded artery within the body of a patient includes an arcuate tubular sheath. A rod is slidably received through the sheath and terminates at a forward end in a tapering, radiused tip. A rearward end of the rod terminates in an enlarged tab dimensioned for passage through the sheath. A pair of apertures formed in the tab allow a bypass artery to be stitched thereto. In use, an entrance incision is formed in a patient adjacent one end of an occluded artery. The radiused tip is inserted through the entrance incision and the sheath and enclosed rod are passed alongside the occluded artery. An exit incision is then formed adjacent the radiused tip. The forward end of the sheath is then pushed through the exit incision. A bypass artery is secured to the tab at the opposite end of the rod, adjacent the entrance incision. The rod is then pulled through the sheath, leaving the bypass artery disposed within the sheath, alongside the occluded artery. The bypass artery is then detached from the tab, and the sheath is removed from the patient, while the bypass artery is held in place. The end portions of the bypass artery are then connected to bypass the occluded artery, and the entrance and exit incisions are closed. The procedure allows a bypass operation to be performed with a minimum number of stitches, resulting in a rapid patient recovery.
