A holder for a highly flexible tissue-type heart valve is disclosed that maintains an implant shape to the valve. The holder may have cusp and commissure contacting supports, and may be attached at all six such supports, or only three. The holder may be flexible to permit inward flexing of the heart valve during implant for greater visibility when implanting using a running suture method. The holder may be formed of flexible wires such as Nitinol, and shaped to resist excessive axial and torsional deformation of the valve. A short handle connector suitable for manual grasping may be attached and stored with the valve, with the handle connector having a coupling for receiving a longer delivery handle. A two stage holder may be utilized to accommodate different implant methods.
A holder for a heart valve, the heart valve having multiple leaflets joined together at a periphery of the valve at valve commissures that are generally axially aligned and evenly disposed about a valve axis, the valve commissures each being disposed between adjacent curvilinear valve cusps along the periphery of the valve, the holder comprising:
A holder for attaching to and holding a heart valve, the heart valve having multiple leaflets joined together at a periphery of the valve at valve commissures, the valve commissures each being disposed between adjacent curvilinear valve cusps about the periphery of the valve generally at an inflow end thereof, the holder comprising:
