Abstract
An implantable infusion port is provided to facilitate delivery of medication to a patient, wherein the infusion port has a substantially reduced internal volume to minimize the quantity of residual medication therein. The infusion port comprises a cup-shaped housing with a self-sealing septurn mounted thereon to define an internal chamber for receiving medication infused through the patient's skin and the septurn via a hypodermic needle or the like. A catheter mounted on the housing communicates with the internal chamber to deliver the medication to a selected site within the patient. A substantial portion of the chamber volume is occupied by inert beads which minimize the open volume of the chamber and thereby maximize medication delivery to the patient.
