He terms petrolatum "the best of the occludants and a good moisturizer, but it is unacceptable in its raw state."

An occludant precursor composition for forming an occlusion mass upon introduction of the precursor into a mammalian body comprising a solution of: a.) partially hydrolyzed polyvinylacetate, b.) a pharmaceutically acceptable solvent, and c) a soluble radio-opaque material.
