Abstract: Blood vessel preservation technology is disclosed wherein harvested blood vessels are attached to stationary attachment fixtures at one end, and to a non-stationary (freely extending) fixture at the other end. The vessel and fixtures are placed within a container. Thereafter, a stream of pulsatile blood is directed through the fixtures and the lumen of the vessel causing the vessel to assume full natural length and aligning the vessel with the container. The pulsatile blood then completely bathes the outside surface of the vessel before being re-circulated. The methods disclosed include those wherein the patient's own circulatory system is part of the circulatory path flowing through the vessel and methods in which the circulatory path is outside and apart from the patient. A pulsatile pump, blood heater and pressure regulator may all be utilized in preferred embodiments of the disclosed methods and devices.

Abstract: A blood vessel preservation device is disclosed comprised of a vessel cannister, cannister cap, vessel alignment insert, pulsatile pump and both inlet and outlet tubing. The vessel canister is advantageously configured as a hollow tube-like structure with a central bore having one open terminus—the proximal terminus—and a closed distal terminus—similar to a large test tube—. Integrated embodiments of the device are disclosed wherein blood is provided from natural circulation and returns thereto. Non-integrated embodiments are also disclosed wherein sufficient blood is provided to the device and thereafter the device functions separate and apart from a patient's circulatory system.

Abstract: A method and device are disclosed directed at harvesting of vessels, such as arteries and veins, especially as required in vessel grafting procedures. The device and method discloses a cannula-like device that provides, identification, capture, manipulation, hemostasis and cleavage of branch vessels from the harvested vessel without need for further devices. In certain preferred embodiments of the disclosed method and device, the disclosed harvesting device achieves branch vessel cleavage and hemostasis without the use of heat producing means such as cautery. In addition, certain embodiments utilize a clip/coil magazine technology so as to enable severance and hemostasis of multiple branch vessels without need for removal of the device from the surgical site.
