ABSTRACT:
A method of cooling selected surface areas of living tissues includes the steps of covering a resilient mass of porous material with a deformable liquid cryogen impervious membrane, conforming the membrane-covered mass to a configuration which corresponds to the size and shape of surface areas to be treated, pressing the preshaped membrane-covered mass into firm engagement with surface areas to be treated, and introducing a controlled supply of liquid cryogen into the mass. The step or pressing the membrane-covered mass into engagement with surface areas to be treated is performed with sufficient force to restrict or inhibit or cut off the normal flow of blood through the tissues thereby permitting the tissues to freeze more rapidly than would be possible if normal blood flow were maintained.
