ABSTRACT:
An improved multiple re-entry implantable septum is disclosed. The septum comprises a casing and a resilient member positioned within the casing. The resilient member has a perforation therein which is compressed closed. An outer side of the casing presents a relatively large surface configured to channel the end of a slender, elongate component such as a needle to a predetermined location at a relatively small bore in the outer side of the casing. The small bore in the casing is located adjacent the perforation in the resilient member. An assembly of a first needle and a cannula positioned over the needle is inserted into the skin so that the end of the needle contacts the relatively large surface of the casing and is channeled to the small bore therein. The bore is dimensioned to prevent passage of the first needle through the casing. The first needle is withdrawn from the casing and skin leaving the plastic cannula in place adjacent the small bore. A second, relatively smaller blunt needle is inserted into the cannula and through the small bore of the casing and the perforation in the resilient member to permit filling an implanted drug reservoir for an implanted infusion device.
