Abstract
A subcutaneously implantable vascular access port includes a base which defines a plurality of fluid cavities separated by a dividing wall configured to provide an outlet duct for each fluid cavity, wherein the outlet ducts are staggered along the length of the dividing wall, a cap configured to receive the base and which includes a plurality of septum access apertures aligned with the fluid cavities, and a single self-sealing septum captured between the cap and the base. An outlet stem exits the base and communicates with the fluid cavities therein. The outlet stem has two prongs formed in a side-by-side configuration extending outwardly from the base. Fluid injected into a fluid cavity through the septum flows through a smooth transition region in which the cross-sectional area is smoothly reduced from the corresponding fluid cavity. A locking sleeve provides radial inward pressure upon the catheter which is slid over the outlet stem, thereby insuring that the catheter remains mounted on the outlet stem.
