Composite implantable biocompatible vascular access port device
First Claim
1. A surgically implantable device for delivering a fluid medication to a body, said device comprising:
- housing means of a biocompatible non-metallic first material defining an interior chamber with communicating inlet and outlet openings, said housing means including first and second components;
a unitary cup-shaped element of a non-reactive second material compatible with said fluid medication and received in and lining the interior surface of said chamber, said cup-shaped element having an upper rim;
self-sealing septum means closing said inlet opening and through which said fluid medication may be injected into said chamber, said upper rim of said cup-shaped element being in tight sealing engagement with the underside of said septum means, and said cup-shaped element and said septum means being sandwiched between said first and second components of said housing means;
said cup-shaped element cooperating in sealing engagement with said septum means to isolate the thus injected fluid medication from contact with said first material of said housing; and
conduit means communicating with said cup-shaped element and extending through said outlet opening to discharge fluid medication from said chamber to the exterior of said housing.

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 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.

11. A surgically implantable device for delivering a fluid medication to or withdrawing a body fluid from a body, said device comprising:
-
a biocompatible non-metallic housing defining an interior chamber and inlet and outlet openings communicating with said chamber, said housing including first and second components; a non-reactive unitary cup-shaped element compatible with said fluids and received in and lining the interior surface of said chamber, said cup-shaped element having an upper rim; a self-sealing penetrable septum closing said inlet opening and providing a means through which said fluids may be injected into or removed from said chamber, said upper rim of said cup-shaped element being in tight sealing engagement with the underside of said septum, and said cup-shaped element and said septum being sandwiched between said first and second components of said housing; said cup-shaped element cooperating in sealing engagement with said septum means to isolate said fluids from said housing; and a non-reactive conduit communicating with the cup-shaped element, and extending through said outlet opening for conveying said fluids into and out of said housing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
