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.

An electrical access port assembly includes an access port unit which is surgically implantable in the body of a patient and a pair of conductive needles which are operative for supplying electrical energy to the access port unit. The access port unit includes a body portion having a pair of access openings therein, a pair of penetrable elastomeric septa in the access openings, and an interior partition which divides the interior of the body portion into a pair of enclosed interior cavities, each of which is accessible through one of the penetrable septa. The access port unit further icludes an electrical contact in each of the cavities and a conductor wire attached to each of the contacts. The septa of the access port unit are self-sealingly penetrable by the conductive needles to electrically connect the needles to the contacts in the cavities in order to supply electrical energy to a predetermined location in the body of the patient through the conductor wires.

An implantable infusion port for dispensing medication in the body of a patient comprises a septum which is preferably integrally molded from a nontoxic, rubberized material and has an interior cavity formed therein for receiving medication in the septum, and a catheter element which extends from the cavity to the exterior of the septum for dispensing medication in the body of a patient. The septum has a rounded dome-shaped configuration, and the infusion port is surgically implantable in the body of a patient so that it is positioned beneath the skin and subcutaneous tissue of the patient. After the infusion port has been implanted in the patient, medication can be introduced into the cavity by inserting a hypodermic needle through the skin of the patient and through the side wall of the septum. The rounded dome-shaped configuration and the integrally molded construction of the septum minimize patient discomfort and provide an increased needle penetration area in the infusion port so that it does not become rapidly damaged by needle penetrations and it can be effectively used over a prolonged period of time without requiring replacement.
