Abstract

A medical valve has a resilient member (22) that is forcibly expanded to an expanded volume from a normal volume. Specifically, the valve operates in a closed mode that prevents fluid flow, and an open mode that permits fluid flow. To these ends, the valve has a housing having an inlet and an outlet, and the noted resilient member (22) within the housing. The resilient member and housing form a fluid channel between the inlet and the outlet. The fluid channel at least in part extends through the resilient member (22). The fluid channel at least in part extends through the resilient member. The fluid channel has a given portion formed by a variable volume portion (54) of the resilient member. The variable volume portion (54) has a normal volume when in the closed mode, and an expanded volume when in the open mode. The expanded volume is greater than the normal volume.
