1. A medical port having an open mode that permits fluid transfer and a closed mode that prevents fluid transfer, the medical port comprising:
a hub having a body forming a hub chamber for containing a fluid, the hub further having a proximal opening to the hub chamber for receiving a medical implement;
a valve member located within the hub chamber and having a radial portion, the valve member configured to close the proximal opening when the medical port is in the closed mode, at least a portion of the valve member being resilient
a first radial fluid channel having a first radial fluid channel opening into the hub chamber, the first radial fluid channel in fluid communication with the hub chamber when the medical port is in the closed mode, the radial portion of the valve member configured to restrict fluid communication between the first radial fluid channel and the hub chamber when the medical port is in the open mode; and
a second radial fluid channel having a second radial fluid channel opening into the hub chamber, the second radial fluid channel in fluid communication with the hub chamber when the medical port is in the closed mode and in the open mode, at least a portion of the valve member within the hub chamber located between the first radial fluid channel opening and the second radial fluid channel opening when the medical port is in the closed mode.
