We consider the two-dimensional boundary value problem of Stefan’s type in a multi-connected domain with nonlinear heat sources arising in cryosurgery. A formulation of the problem for the case of two needle cryoinstruments cylindrical shape, fully embedded in biological tissue is showed. On this example, a method for investigation of such problems, reducing to the successive solution of two-dimensional problems in the areas of simpler forms is proposed. A feature article considered models is the fact that they take into account the actual effect observed spatial localization of heat.
