Abstract
Small compression type injection site in the form of a self-sealing septum-like member that is self-sealing for hypodermic needle punctures and the like and a method of manufacture. Compressive stresses are introduced into a stretched elastomeric rod, whereby the decreased diameter cross section is maintained by placing a wrapping around and about the stretched rod and adhesively sealing it thereto. Sliced cross-sectional pieces of the rod then provide injection sites to be incorporated into the wall of an implantable prosthesis as by bonding or the like.
