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.
Claims4
A valve folding assembly comprising:
- a valve holder comprising an open-faced, semi-cylindrical flexible tube having a curvature and length substantially matching that of a prosthetic valve;
- a plurality of elongate locking bars operably connected to said semi-cylindrical flexible tube along a longitudinal axis thereof;
- one or more suture slots located on the valve holder;
- a stopper ring structured to at least partially circumferentially surround said semi-cylindrical tube;
- and
- a valve receptacle configured to receive the valve holder, said valve receptacle including at least two guide rails attached to a disk, said guide rails adapted to engage the locking bars of the valve holder.
