Abstract
An improved septum-containing device having at least one polymeric septum with at least one corresponding plate having at least one aperture through which a septum-piercing device, usually a non-coring needle, may pass. The aperture exerts force on the non-coring needle to reduce the occurrence of inadvertent needle dislodgement from a septum-containing device. In a preferred embodiment the aperture is sized such that when the indwelling needle no longer is essentially perpendicular to the aperture, the side wall structure of the aperture exerts frictional forces on the needle. The present invention may be directed towards an implanted septum-containing device such as an infusion port as well as a non-implanted, externalized device with a polymeric septum such as a luer injection cap.
