ABSTRACT:
A vascular access port enclosing a pair of distinct fluid reservoirs includes a two-piece housing that captures an integrally-formed compound septum to seal both of the fluid reservoirs for selective access with a hypodermic needle. The housing includes a base that defines the fluid reservoirs and a cap in which the base is received with the compound septum therebetween. The compound septum includes two distinct target domes that are exposed to the exterior of the housing through respective access apertures in the cap, when the compound septum is captured in the housing. A planar septum web interconnects and encircles the target domes. The side of the septum web opposite from the target domes is formed into a recessed isolation groove that traverses the septum web between the target domes. Sealing ridges depend from this side of the septum web on either side of the isolation groove. The outlet stem of the access port is integrally formed with the base of the housing. In the base an open-topped fluid channel communicates from each fluid reservoir to a corresponding enclosed fluid passageway in the outlet stem. The open top of each fluid channel is closed by a portion of the compound septum captured in the housing.
