Abstract:
A needleless injection port assembly includes first and second body parts and a resilient barrier received within the body. A cannula attached to the first body part is received within an internal cavity of the resilient barrier. The resilient barrier is moveable between a less axially compressed first position in which fluid flow through the injection port assembly is prevented and a more axially compressed second position in which fluid flow through the assembly is allowed. An interference fit is provided between the resilient barrier and the cannula to seal against fluid flow through the cannula when the resilient barrier is in the first position. The cannula has an internal fluid passageway with a non-circular cross section providing increased fluid flow.

Claim (Index 15):
An injection port assembly, comprising:\n a body having a first mating structure and a second mating structure configured to be coupled to the first mating structure; a resilient barrier configured to be received within the body and compressible from a less compressed first position in which fluid flow through the injection port assembly is blocked to a more compressed second position in which fluid flow through the injection port assembly is permitted, the resilient barrier including an internal cavity; and a hollow cannula coupled to the first mating structure and configured to be received within internal cavity of the resilient barrier, the hollow cannula having a longitudinal central axis, the hollow cannula including:\n a cannula distal end portion configured to extend through the resilient barrier when the resilient barrier is in the more compressed second position; \n at least one lateral outlet window formed in the cannula distal end portion, the at least one lateral outlet window having a window width perpendicular to the longitudinal central axis; and \n an internal fluid passageway defined in the hollow cannula and configured to communicate the at least one lateral outlet window with a fluid conduit connected to the first mating structure, the internal fluid passageway having a non-circular cross section axially proximal from the window, the non-circular cross section having a cross section area greater than a cross section area of a circle of diameter equal to the window width.
