ABSTRACT:
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.
