Claim:
1. An attachment ring assembly for attaching an inflow conduit to the heart, the assembly comprising: a ring wall having a distal end and a proximal end, the ring wall forming a fluid passageway between the distal end and the proximal end; a cuff disposed at the distal end, the cuff extending radially outward from the ring wall and configured for direct attachment to the heart; and a ring valve within a valve housing attached to the ring wall, the ring valve configured to prevent fluid flow from the distal end to the proximal end, wherein the ring valve is configured to flex to an open state in response to passage of an instrument through the ring valve and the fluid passageway, and is configured to move autonomously to a closed state that prevents fluid flow from the distal end to the proximal end when the instrument is subsequently removed from the ring valve, wherein the fluid passageway and the ring valve are configured to receive an inflow conduit for a heart pump through the fluid passageway and the ring valve, and wherein the valve housing is divided into two valve housing halves that are separated by an imaginary plane coincident with a longitudinal axis of the valve housing, each valve housing half is movable relative to the other valve housing half, and each valve housing half includes half of the ring valve.
