摘要:
A hemostatic valve assembly is disclosed. The assembly comprises a housing (110, 210) having a sidewall that tapers radially inwardly towards the housing distal end. A valve member (170, 270) having an open proximal end and a tapered distal end with an orifice formed therein is disposed within the housing chamber. The valve member (170, 270) is deformable between a closed configuration in which the orifice is substantially closed and an open configuration in which the orifice is open. A biasing member (180, 280) disposed proximal to the valve member (170, 270) is moveable between a longitudinally compressed condition and a longitudinally expanded condition. When in an expanded condition, the biasing member (180, 280) pushes the valve member longitudinally and against the tapered sidewall of the housing. The tapered sidewall of the housing urges the distal end of the valve member (170, 270) radially inwardly, thus urging the orifice to the substantially closed configuration.
