Abstract
A septum contains at least one internal chamber along the central axis of the septum. The chamber provides relief space into which the sealing sections of the septum can deform as a needle passes through the septum. Incorporation of the chamber reduces surface area contact and friction between the septum and needle, which results in reduced septum tearing and reduced production of particulate matter from abrasion.
