An intravascular valve component broadly includes a valve case and a flexible pressure-actuated flow control valve. The valve case includes attached proximal and distal case portions that present respective spaced apart fluid ports and a fluid passageway extending between the ports. The flexible pressure-actuated flow control valve is disposed within the fluid passageway and includes a slitted central valve wall and an annular flange surrounding the central valve wall. The annular flange includes a radially-extending flange wall and a projection extending axially from the flange wall, with the projection engaging one of the case portions to restrict radial movement of the flow control valve relative to the valve case.

What is claimed is: 1. An intravascular valve component comprising:a valve case including attached proximal and distal case portions,said case portions presenting respective spaced apart fluid ports and a fluid passageway extending between the ports; anda flexible pressure-actuated flow control valve disposed along the fluid passageway to control fluid flow therethrough,said valve including a generally dome-shaped central valve wall having a slit at a general apex of the dome and an annular flange surrounding the central valve wall,said annular flange including a radially-extending flange wall having a radially outermost edge and a valve-seating projection extending axially from the flange wall and spaced radially outwardly from said valve wall and between said outermost edge and the valve wall to permit said slit to flex between open infusion and aspiration configurations,one of said case portions presenting an opening,said opening presenting a generally arcuate-shaped groove having a tapered inner surface,said projection being generally arcuate-shaped and having a tapered outer surface,said flange wall being engagingly received between the attached case portions,wherein said tapered inner surface of the groove and said tapered outer surface of the projection are complementally shaped such that the projection is received within the groove and engages the groove to substantially restrict radial movement of the flow control valve relative to the valve case and to coaxially align the valve with the one of said case portions presenting said opening to thereby position the valve wall concentrically within the fluid passageway.
