1. A valve assembly configured for use with a medical device having a distal end, a lateral surface and a connector portion, the valve assembly comprising:
a hub configured to receive the medical device in a proximal end;
a valve coupled to a chamber within the hub and comprising a barrier layer at a far end and a wall portion;
the wall portion extending proximally from the barrier layer towards a near end of the valve, the wall portion defining a valve cavity therein, the barrier layer having at least one slit extending therethrough;
wherein a thickness of the barrier layer is greater than an offset distance measured between an inner surface of the wall portion and a surface of the chamber;
wherein the valve is configured for positioning in the hub such that the wall portion engages the surface of the chamber; and
wherein when closed, the valve prevents leakage caused by pressure of fluid flow against the valve and wherein insertion of the medical device into the valve cavity causes the distal end of the medical device to deform the barrier layer to open the at least one slit to permit fluid flow through the barrier layer, while the lateral surface of the medical device engages the wall portion at an interior of the valve cavity causing the wall portion to engage the surface of the chamber.
