ABSTRACT:
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 metallic chamber liner, and a metallic delivery conduit. The septum closes the inlet opening and provides a seal through which fluids may be injected into or withdrawn from the chamber. The metallic chamber liner underlies and seals against the septum and cooperates with it to isolate the injected fluid medication from the housing and from leakage into body tissue. The metallic 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.
