Abstract
A surgical apparatus includes a hub, a closure valve, an internal seal member, and a spring. The hub defines an internal chamber. The closure valve is disposed within the internal chamber and defines an internal bore extending therethrough. The closure valve is movable relative to the hub between a first position, substantially sealing the internal chamber, and a second position, establishing a fluid passage extending completely through the hub. The internal seal member is disposed within the internal bore of the closure valve and is movable relative to the closure valve between a closed position, substantially sealing the internal bore, and an open position, establishing an internal passage, different from the fluid passage, extending completely through the closure valve. The spring is disposed within the internal chamber and is configured to bias the internal seal member towards the closed position, thereby biasing the closure valve towards the first position.
