Abstract: A cassette is received within a sleeve having an open end. Specially folded flaps at the open end are applied to center the cassette in the sleeve and to reduce a width of the open end of the sleeve.

Abstract: A sterilization container for sterilizing, storing and transporting instruments is formed of a liquid crystal polymer, such as a wholly aromatic polyester. The container is strong yet has thin walls so that condensation is minimized. Suitable polymers include wholly aromatic polyesters such as: polybenzoate-naphthalate; polybenzoate-terephthalate-bisphenol-isophthalate; polybenzoate-terephthalate-ethylene glycol; and polynaphthalate-amino terephthalate.

Abstract: A sterilization system uses a sterilization process monitoring device which is capable of indicating the efficacy of the sterilization process. To enhance accuracy of the monitoring function, the monitoring device is located in such a fashion that an antimicrobial agent used in the process can only reach the monitor through an area containing the article to be sterilized.

Abstract: A sterilization container has an improved elastomeric instrument holder. The instrument holder comprises a panel of elastomer having a projection depending downwardly therefrom and received within an perforation through a perforated surface within the container to hold the panel thereto. An aperture through the panel is adapted for receiving and holding an instrument to be sterilized. An inner surface of the aperture is adapted to have a reduced area of contact with an instrument received within the aperture. For example, the surface may comprise chamfers which meet to form a sharp ridge which contacts the instrument. The contact surface may also be textured to reduce the area of contact with the instrument. Alternatively, the surface may be formed of a material which is sufficiently permeable to a sterilizing gas so as to allow the area of the instrument in contact with the surface to receive a sufficient amount of sterilizing gas to become sterilized.

Abstract: In a flexible endoscope having a flexible insertion tube comprising a tubular, biocompatible elastomeric outer covering thereabout which encloses an interior space, the improvement according to the present invention comprises a vapor barrier between the outer covering and the interior space. Thus, vapor, such as hydrogen peroxide or other sterilants, passing through the outer covering from an atmosphere thereabout is prevented from entering the interior space by the vapor barrier. Further, the vapor is thus prevented from interacting with substances, such as lubricants, within the interior space to produce agents harmful to the elastomeric covering.

Abstract: A tray and process for hydrogen peroxide vapor sterilization of medical articles. The tray includes a bottom surface and side walls defining a space to receive articles to be sterilized. The bottom surface of the tray includes a number of inlet passages and wells with a known volume. In the process of the present invention, articles to be sterilized are placed in the tray, and aqueous solutions of hydrogen peroxide is delivered into the tray. When the excess hydrogen peroxide is drained through the inlet passages, a known volume of peroxide remains in the wells. Such remaining hydrogen peroxide is then vaporized to achieve sterilization.
