Abstract
A tubular interconnected device for coupling within the circulatory system of a living being. The device includes first and second connective members formed of rigid materials of high tolerance construction. The connective members each have an internal sealing edge with mating faces for developing sealing contact when interlocked. A sleeve is attached to one of the connective members and operates with respect to the second connective member to draw the two into an aligned, locked configuration, with force imposed at the sealed junction of the mating faces. Distal edges at the extremities of each connective member are permanently sealed to open ends of the circulatory system to which the interconnect device is coupled. Specific structure is disclosed for use in connectioin with an artificial heart implant.
