  • Patent number: 4761326
    Abstract: A sterilizable, water vapor permeable, bacterial barrier foam-coated medical fabric suitable for use as a medical instrument wrap or CSR wrap which features a nonwoven textile-type substrate coated with a continuous network of an open cell microporous foam that forms a network of interconnected cells distributed among and covering nearly the entire surface of the substrate. This foam extends into the substrate itself and presents a network of interconnected cells that form a tortuous path from the face of the fabric to the opposite side of the fabric to define a bacterial barrier to inhibit or stop the passage of bacteria, yet permits steam and water vapor to pass into and out of the fabric.
