A surgically implantable access port device is disclosed. The device includes a housing, a self-sealing septum, and a cup. The housing includes an internal bore leading to an upper opening, and the bore is defined by a cylindrical side wall having an inwardly protruding ledge located beneath the upper opening. The self-sealing septum is received in the bore at a location closing the upper opening and bearing against the ledge. The cup is received in the bore, and cooperates in a fixed association with the side wall of the bore to compress the septum against the ledge. The cup cooperates with the septum in defining a liquid retaining chamber. The device further includes a conduit connected to the cup and leading from the chamber to the exterior of the housing. Liquid may be injected into or removed from the chamber by penetration of the septum and passage through the conduit.
