Abstract
The present invention provides a portal for subcutaneous implantation, where the portal includes a housing having a first end, a second end, an inner wall, and a lumen between the first and second open ends. In one preferred embodiment, the first open end of the housing is sealed by a elastomeric septum, which has been injection molding into place. The elastomeric septum is bonded to the inner wall of the housing adjacent the first open end. The second open end is sealed to define a reservoir accessible through the septum.
