Abstract

A color-coded bioprosthetic valve system having a valve with an annular sewing ring, and a valve holder system with a holder sutured to the ring of the valve, a post operatively connected to the holder, and an adapter sutured to the post and having a color associated with the valve model and/or size. For example, the adapter may be blue to indicate that the valve of the system is a mitral valve of a particular type and/or size. The system may also include a flex handle that is configured to engage with the adapter. The handle has a color associated with the adapter such that a user is able to visually determine that the handle color matches the valve model. For example, the handle may have a grip that is colored blue to match the blue color of the adapter. Accordingly, the color-coded system enables users to confirm easily that the correct accessories such as the sizer or flex handle are being used with the correct valve.
