  • Patent number: 4882162
    Abstract: An artificial skin or bandage is formed from an elastomeric layer which is surfaced by a fibrous wound contacting layer which is first formed into a fabric and subsequently degraded by heat hydrolysis or other degradative treatment into a form which could no longer be formed into a fabric but which forms an ideal bioabsorbable wound contact surface in which damage to the newly formed, fragile epidermus is minimized.
