Abstract
A device for retaining a natural tissue heart valve and stent assembly during storage and transportation prior to implantation of the valve. The device consists of an open-ended, cylindrical valve case having an internal support for a valve support ring adapted to grasp the valve stent. A retainer holds the valve support ring in position within the valve case. The assembled device is stored in a jar containing a preserving liquid until the valve is to be implanted.
