<p>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. 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 adjacent tissue. In the case of RF treatment, healthy surrounding tissue may be ablated. There is also a possibility of thermal damage to surrounding, non-targeted tissue. The above risks may be lessened or avoided with the use of an interface shield (20) between the target region and adjacent body tissues to shield surrounding organs (D) and tissue from treatment effects.</p> |
