Abstract
A subcutaneous implantable access port is formed of a housing having a pair of noncircular fluid cavities enclosed therein by a floor, walls upstanding from the floor, and a self-sealing septum positioned above each fluid cavity. The housing is constructed of a base, a septum support, and a cap. 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. The prongs are formed within the stem channels in fluid communication with the fluid cavities. Protruding radially outwardly from the portion of said prong is a barb. Fluid injected into the 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.
