Abstract
Abstract A surgical blood vessel holding device is described having shank means in a middle region with a holder on one end and a narrow prong on the other end. The prong is provided with a hook extending laterally from the side thereof. The prong is adapted to be inserted into the open end of a blood vessel until the hook reaches the distal end of the vessel. The hook then pierces the vessel wall, allowing the device to dispose the end of blood vessel in facing relationship with respect to an opening in the wall of another blood vessel. The blood vessel can be locked onto the hook. Thereupon, suturing of the vessels is initiated, but not completed. The prong is then unhooked and removed and the suturing process is completed without the device to provide a continuous blood flow path between the two blood vessels.
