A double-sterile package for critical-use medical apparatus includes an inner first container including an outer boundary wall impervious to microorganisms and being closed except for defining a hole. A patch of gas-permeable micro- porous sheet material is secured to the outer boundary wall spanning and closing the hole. The gas-permeable sheet material is sufficient to exclude environmental microorganisms from entering the inner first container. The first container is received into and nested within a conformal second container also having a boundary wall impervious to microorganisms and being closed except for defining a hole. This hole of the second container is also closed by a patch of the gas-permeable micro-porous sheet material, and the holes of the first and second containers are in gas-flow communication with one another. The medical apparatus within the nested containers is sterilized by evacuation of air and introduction of a sterilizing gas via the gas- permeable patches. Removal of the sterilizing gas provides a packaged sterile medical apparatus which may be transported, stored, and handled with no further need to additionally protect the sterility of the apparatus, or for further sterilization after the package is opened immediately prior to use of the apparatus.

Un emballage stérile double pour des appareils médicaux critiques comprend un premier emballage interne ayant une paroi externe imperméable aux micro-organismes et fermée, à l'exception d'une ouverture. Une pièce d'une feuille d'un matériau micro-poreux et perméable aux gaz est fixée à la paroi externe pour couvrir et fermer cette ouverture. La feuille de matériau perméable aux gaz suffit pour empêcher les micro-organismes de l'environnement d'entrer dans le premier récipient interne. Le premier emballage vient se loger dans un second emballage de forme adaptée ayant également une paroi externe imperméable aux micro-organismes et fermée, à l'exception d'une ouverture. Cette ouverture du second emballage est également fermée par une pièce d'une feuille de matériau micro-poreux et perméable aux gaz et les ouvertures des premier et second emballages permettent une communication mutuelle entre ces emballages. L'appareil médical dans les emballages superposés est stérilisé par l'évacuation de l'air et l'introduction de gaz stérilisant par l'intermédiaire des pièces perméables aux gaz. L'élimination du gaz stérilisant permet d'avoir un appareil médical stérile qui peut être transporté, mis en attente et manipulé sans autre besoin de protection additionnelle pour assurer cette stérilité et sans besoin de stérilisation après que l'emballage a été ouvert, juste avant son utilisation.
