A composite implantable biocompatible vascular access port device for delivering a fluid medication to or withdrawing a fluid medication from the body. The device has a non-metallic housing defining an interior chamber with inlet and outlet openings, a self-sealing penetrable septum, a non-reactive chamber liner, and a non-reactive delivery conduit. The septum closes the inlet opening and provides a seal through which fluid medication may be injected into the chamber. The chamber liner underlies the septum and cooperates with it to isolate the injected fluid medication from the housing and from leakage into body tissue. The delivery conduit communicates with the interior of the liner, and extends through the outlet opening to convey fluid medication to the exterior of the housing.
