摘要:
An improved holder and storage system for prosthetic heart valves that pre-shields or pre-constricts the commissure posts of the valve to prevent suture looping. Pre- shielding and pre-constriction mean at the time of manufacture, so that the valves are stored with the commissure posts shielded and/or constricted. The holders may have solid legs that directly contact and constrict and hold the commissure posts without the use of sutures in tension that might creep over the time in storage. The holder may have a base in contact with the inflow end and a shaft portion that projects through the valve leaflets and cooperates with movable legs on the outflow end of the valve in contact with the commissure posts. The holders may, alternatively, have flexible leg members that extend through the valve and have distal end portions configured to extend over and shield the tips of commissure posts.
