A pouch (10) for packaging a medical device to be sterilized by a gas sterilization process has a first surface (11) and a second surface (12), which are sealed together during assembly at the edges (13) to form an outer envelope (14) having a sealable opening (16) along one side (17) thereof for receiving the medical device in use. The pouch (10) is internally divided into a device receiving pocket (18) and a venting section (19) by a gas permeable microbe impermeable partition (20). An openable vent (21) is located in the first surface (11). This flap (22) curls in response to a raised temperature thus exposing an aperture (23) through which the sterilizing gas can enter the pouch (10). When the temperature returns to ambient the flap (22) flattens out and reseals the aperture (23). In use a medical device to be packaged is placed in the device receiving pocket (18) of the pouch (10) and a desiccant strip, if required, is placed in the venting section (19). The pouch (10) is then sealed along the edge (17) and is sterilized. An adhesive patch (not shown) can then be placed over the flap (22) to provide a watertight seal. As the pouch (10) is watertight, following sterilization, it does not have to be stored under aseptic or humidity controlled conditions. |
