Abstract
A device for use in cryopreservation of blood vessels comprising a pair of stylets insertable into the ends of a dissected blood vessel segment. The stylets are mountable on a support track whereby the blood vessel can be distended and supported during cryopreservation procedures. Also disclosed is a freezing and thawing profile capable of maximizing endothelial cell survival. The use of chondroitin sulfate or similar compound is discussed as a novel cryoprotectant and DMSO is disclosed as a penetrating cyroprotectant.
