Abstract
A method of crimping and loading prosthetic heart valves comprises folding a crimping sheet to form a spiral wrapped around a heart valve; manually rolling and tightening the spiral to compress the valve inside the spiral; inserting the tightened spiral wrapped around the valve into a cannula; and displacing the valve out of the tightened spiral and into the cannula. A kit for crimping and loading the valve into a delivery device comprises a crimping sheet foldable to form a spiral wrapped around the valve, the spiral manually rollable and tightenable to compress the valve wrapped inside the spiral, so that the tightened spiral is slidably insertable into a lumen of a cannula for delivering the valve; and a plunger sized for insertion into the tightened spiral to displace the heart valve out of the spiral and into the lumen of the cannula.
