Abstract
A folding device used to fold a cardiac valve is disclosed. Also shown are methods and system for holding and delivering a cardiac valve during implantation. The folding device facilitates folding either a stented or unstented prosthetic valve prior to insertion into a valve annulus. A delivery system is provided to allow a user to measure the patient annulus to select the prosthetic valve size and insert a folded prosthetic valve into a target site. Methods for using the folding device and delivery system are also disclosed.
