ABSTRACT:
The present invention on embodies a device and method for creating a bloodless field at an incision site in a blood vessel. The invention includes a perfusion tube for allowing perfusion of blood past the incision site. A pair of conical occlusive members are mounted on either end of the perfusion tube for preventing blood from flowing into the surgical site. A tubular stem depends from the tube, and includes a movable stopper which may be moved between a first position for blocking blood flow through the perfusion tube, and a second position for enabling blood to perfuse through the perfusion tube. With the movable stopper in the first position, a first end of the device may be inserted through a small incision into the upstream side of a blood vessel so that the blood flow is blocked. The second end of the device may then be inserted in the downstream side of the incision. The stopper may then be moved to the second position so that blood is free to flow through the perfusion tube. The downstream tissue will thus continue to receive a supply of oxygenated blood, while the portion of the blood vessel between the occlusive members remains blood-free.
