Abstract
A system includes a heart valve and a device that functions to minimize a possibility for suture becoming entangled with a commissure post of the heart valve during an implantation procedure. In some examples, the device is a suture guard that includes one or more features that deflect suture to help minimize entanglement of the same with the commissure posts of the heart valve. In some examples, the features operate to deflect the commissure posts radially inwardly, while in other examples, the features overlay the commissure posts without deflecting that same.
