Abstract
A method for the manufacture of an artificial organ having a film of a fat-soluble vitamin deposited on the surfaces of parts of said artificial organ susceptible to contact with body fluid in motion through a zone for flow of said body fluid within said artificial organ, which method is characterized by the steps of causing a solution of said fat-soluble vitamin in an organic solvent to flow into said zone for flow of body fluid within said artificial organ and allowing said parts to be amply wetted with said solution, then discharging an excess of said solution out of said artificial organ, and subsequently drying said solution deposited on said parts thereby expelling said organic solvent from the solution. The invention also provides a method for sterilizing said artificial organ after contact with a physiologically harmless liquid.
