Patent ID: 8079990

Claim:
A subcutaneous access device including a port body comprising: (a) a reservoir; and (b) an outlet having a proximal tip joined to the reservoir and a distal tip, wherein the shape of the reservoir and the outlet are defined by the inner surface of the port body; wherein the reservoir and the outlet are in fluid communication and defined by an inner sidewall and an outer sidewall forming lateral boundaries in opposition defining a flow passage along the reservoir to the distal tip of the outlet; wherein the lateral boundaries transition into an upper surface of the reservoir and a bottom surface of the reservoir via a smooth curve; and wherein further the inner sidewall is globally tangent along the reservoir surface and the outer sidewall is tapered and transitions from the reservoir to the outlet defined by a radius of curvature R 1 having an angle θ that is greater than 90° and up to 225°, which curvature R 1 transitions at the proximal tip of the outlet into a curvature R 2 extending to the distal tip of the outlet.
