Abstract
An access port for subcutaneous implantation is typically connected to a catheter, a distal portion of which is disposed within a vein or other vessel of the patient. The access port described herein is configured with enhanced fluid handling features to improve fluid flow therethrough while reducing the likelihood of clotting or occlusions in the attached catheter, thus improving system patency. The access port includes a body defining a reservoir, a needle-penetrable septum covering the top opening of the reservoir, a stem including a lumen in fluid communication with the reservoir, and a volume control device positioned in the reservoir. The volume control device includes a floor designed to move from a first position below the side opening to a second position adjacent the bottom surface, and a spring element positioned between the floor and the bottom surface, the spring element biasing the floor in the first position.
