US Patent 7510545 Needleless access port valves

Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves having a pliant valve body configured to expand to accommodate a plug when the same is pushed by a syringe or a medical implement and contract when the syringe or medical implement is removed to return the plug to its original position. The plug can move distally and tilt when inside the pliant valve body or remain generally upright when its top surface incorporates flow channels. Interior baffles are included for fluid flow through the interior cavity of the valve. The baffles can vary in shape, number, contour, and can include a ramp.
