Heart valve holder having a locking collar

摘要

A prosthetic heart valve holder includes a set of jaws. Each jaw includes a distal end adapted for coupling to the prosthetic heart valve and a proximal end. A hinge assembly pivotally couples the jaws together between the distal and proximal ends. The hinge assembly allows movement of the jaws between an engaged position for grasping the prosthetic heart valve and an disengaged position in which the prosthetic heart valve is free from the distal ends. A locking collar is attached to the jaws and is movable between a first position in which the proximal ends are free from the collar, and a second position in which the collar holds the proximal ends of the jaws whereby the distal ends are held in position to engage the prosthetic heart valve.
