  • Method for preservation of biological tissue
    Patent number: 5431952
    Abstract: A method for silicone polymer impregnation and curing in tissue to preserve the tissue. The tissue is frozen without use of an intermediary solvent and then freeze-dried using a first vacuum. The tissue is then immersed in a non-flammable degreasing solvent, particularly 1,1,1-trichloroethane to remove lipids and the like from the tissue. The tissue is then impregnated with a silicone polymer precursor and a curing agent, and then cured under a second vacuum in a chamber (23). The impregnated polymer silicone precursor is then cured in the tissue. The tissue is preferably an anatomical specimen.
