ABSTRACT:
A mandrel assembly supports an umbilical cord during the shaping and curing of the cord for use as a vascular graft. The mandrel assembly has a pair of mandrel members adapted to be releasably connected in end-to-end relation. Adjacent end sections of the mandrel members have reduced cross sectional shapes to provide the graft with a Venturi throat. Each mandrel member has a low friction outer surface to facilitate the insertion and withdrawal of the mandrel member from the lumen of the umbilical cord.
