  • Patent number: 5715583
    Abstract: The present invention is directed to an apparatus and method for preserving cadavers. The apparatus is preferably comprised of a container that receives a cadaver, which cadaver has first been placed into a multi-layered plastic bag of the type used in the vacuum-packing industry. The container has the ability to be sealed in a substantially air-tight manner. Located on or coupled to the container is a gas evacuation apparatus, which evacuates substantially all of the gases within the container, the bag, and the cadaver. The cadaver is then sealed using a sealing apparatus located within the cadaver. The cadaver, in the sealed bag, may then be removed.
