ABSTRACT:
A surgically implantable infusion port includes a housing portion, a penetrable elastomeric septum portion which cooperates with the housing portion for defining an interior cavity and a catheter element which extends outwardly from the interior cavity for dispensing medication therefrom at a predetermined location in the body of a patient. The elastomeric septum portion is penetrable by a hypodermic needle for dispensing medication in the interior cavity, and it is laterally compressed to enhance the ability of the septum portion to reseal itself after being repeatedly penetrated. A septum assembly including a similar laterally compressed septum element can also be utilized as a penetrable barrier between various liquids and gases.
