The present invention provides improved methods, systems, and kits for protecting body tissues which are adjacent to tissues undergoing thermal treatment. Thermal treatment is often prescribed for tumors and other disease conditions within body organs and other tissue masses. The methods, systems, and kits are particularly useful for treating tumors which lie at or near the surface of an organ, such as the kidney, pancreas, stomach, spleen, and particularly the liver. One risk of treating such tumors is the possibility of mistargeting the tumor and penetrating a delivery cannula or portions of a treatment device beyond the surface into the adjacent tissues or organs. In the case of radiofrequency or electrosurgical treatment, healthy surrounding tissue may be directly ablated. An additional risk, present even when the tumor is correctly targeted, is the possibility of thermal damage to the surrounding, non-targeted tissue. In radiofrequency or electrosurgical treatment, heat may dissipate into surrounding tissues which are more fragile and heat sensitive than the tissue in the organ being treated, thus causing unwanted tissue damage. These risks and others may be lessened or avoided with the use of an interface shield between the target region and adjacent body tissues to shield surrounding organs and tissue from treatment effects.

Fibrous sheets are coated or impregnated with a biodegradable composition to render the sheets more resistant to penetration by liquids. Biodegradable polymer blends suitable for use in coating or impregnating a fibrous sheet can be manufactured from at least one type of polyhydroxybutyrate, optionally in combination with at least one additional biodegradable polymer (e.g., a “hard” biodegradable polymer having a glass transition temperature of at least about 10° C. and / or a “soft” biodegradable polymer having a glass transition temperature less than about 0° C. Sufficient inorganic filler may be included so as to render the treated sheet microwaveable. The biodegradable polymer compositions are especially well-suited for coating or impregnating paper sheets, e.g., 12-15 lb / 3000 ft2 tissue paper to yield food wraps. Food wraps will typically be manufactured to have good “dead-fold” properties so as to remain in a wrapped position and not spring back to an “unwrapped” form.
