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 clastomeric 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.
Point d'injection du type à compression et de petite taille, se présentant sous forme d'un élément du type septum auto-obturant pour des ponctions d'aiguilles hypodermiques et autres, et procédé de fabrication. Des contraintes de compression sont appliquées à une tige élastomère étirée, et on maintient la section de la tige à un diamètre réduit au moyen d'une enveloppe placée autour de la tige et fixée à cette dernière par adhésif. Des parties de la tige, coupées dans le sens transversal de celle-ci, permettent d'obtenir des points d'injection destinés à être incorporés, par collage notamment, dans la paroi d'une prothèse implantable.
