    Abstract: A prosthetic valve assembly includes a support structure and a valve component. The support structure includes a first frame and a sealing member. The first frame includes a lumen extending between inflow and outflow ends. The sealing member extends inwardly into the lumen of the first frame and includes a first end wall defining a first orifice, a second end wall axially spaced from the first end wall and defining a second orifice, and an inner sleeve extending axially from the first end wall to the second end wall and spaced radially inwardly from the first frame. The valve component includes a second frame and a valve structure supported inside of the second frame for permitting blood flow through the valve component in one direction and blocking blood flow in the opposite direction. The valve component is configured to expand within and engage the inner sleeve of the sealing member.
