Abstract:
A method for selective thermal ablation of a tissue to be treated while limiting thermal damage to a protected tissue, comprising:positioning an energy radiator adjacent to said tissue to be treated such that said protected tissue is between said tissue to be treated and said energy radiator; positioning a fusion material between said energy radiator and said protected tissue such that convection transfer of heat may occur between said protected tissue and said fusion material; radiating energy from said energy radiator to ablate said tissue to be treated; limiting temperature rise in said protected tissue by convection transfer of said heat between said protected tissue and said fusion material; and limiting temperature rise in said fusion material by melting said fusion material from a first physical state to a second physical state due to said convection transfer of said heat between said protected tissue and said fusion material, and wherein said fusion material is a solid in said first physical state and a liquid in said second physical state.
