IMPROVED SELF-SEALING INJECTION SITES AND PLUGS, IMPLANTABLE PROSTHESIS AND OTHER DEVICES UTILIZING SAME AND METHOD OF MANUFACTURE

摘要

Small compression type injection site in the form of a self-sealing septumlike 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 access site as by bonding or the like.
