摘要:
A valve cover apparatus for use in a medical assembly including a prosthetic valve and a valve delivery apparatus. The valve cover apparatus includes a housing, a chamber disposed within the housing for receiving a prosthetic heart valve in an at least partially expanded state, a tapered surface defining a portion of the chamber, and a lock ring that is axially movable over at least a portion of the housing between a locked position and an unlocked position. The tapered surface is enables loading and/or guiding of the prosthetic heart valve from the chamber of the valve cover apparatus into a delivery sheath of the valve delivery apparatus and transition the prosthetic heart valve to a radially compressed state. The lock ring restricts movement of the valve cover relative to the delivery sheath when in the locked position, and enables movement of the valve cover when in the unlocked position.
