Abstract: The paper considers the mathematical model of the biological tissue cryo-destruction process constituting the two-measure Stefan's type boundary problem. The method of its sufficiently complete analysis for the case of cylindrical cryoinstrument with the full penetration in tissue has been worked out. The computer program implementing the proposed algorithm has been developed.

Keywords: the Stefan's type problem, cryosurgery, space localization of heart.
