Abstract
A medical valve has an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the medical valve has a housing with an inlet portion and an outlet portion, a rotating member having a protruding member, and a resilient member with a complimentary surface that mates with the protruding member. The inlet portion and outlet portion of the housing compress the protruding member into the resilient member to bias the valve to the closed mode.
