  • Tissue destruction in cryosurgery by use of thermal hysteresis
    Patent number: 5654279
    Abstract: Cell and tissue destruction by cryoablation is enhanced by the perfusion of the cells with thermal hysteresis proteins prior to the cryogenic freezing. The effect of the proteins is to promote the growth of spicular ice crystals in the intracellular fluid which destroy the cell by piercing the cell membrane. This decreases the incidence of cell preservation by freezing, thereby permitting a more uniform and controllable destruction of undesirable tissue by the cryoablation technique.
