ABSTRACT:
A plastic band is secured around the outside of a prosthetic heart valve adjacent the sewing cushion to protect the valve leaflet material against inadvertent needle punctures and tears while sutures are being placed through the sewing cushion. The band is held in place by a single retention suture which passes through the band and sewing cushion of the valve and extends across the valve orifice. The protector is especially desirable for use with pericardial tissue valves having the tissue mounted on the outside of the valve stent where the tissue is particularly exposed and susceptible to needle damage.
