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.

Implantable plural fluid cavity port

The invention comprises an infusion device for infusing fluids to a patient having a plurality of, preferably two, enclosed open cavities, equipped with self-sealing septums. The device comprises a housing having a base, a cap, and a dual-port stem exiting the base and communicating with the open cavities. The cap comprises a tactile raised locating ridge positioned between, and adjacent to, the septums or other self-sealing means so configured that a doctor can simultaneously determine where each septum is located as soon as he locates the single ridge. A doctor can also differentiate between each septum, and determine the location of structures associated with each septum. Furthermore, the ridge is so configured that it does not enclose an area of tissue of the patient, thereby precluding the problem of necrosis.
