Abstract
A sizing apparatus for a supra-annular heart valve comprising a sizing probe mounted on a bendable shaft. The sizing probe comprises a cylindrical body with a proximal surrounding lip, the body and lip having a combined height equivalent to a similar height of the supra-annular heart valve. The body has an outside diameter which corresponds to that of the body of the supra-annular heart valve, and the lip has an outside diameter which corresponds to that of the sewing ring brim. Proximal from the lip is an annulus sizer having a shape corresponding to the interior opening or orifice of the selected heart valve. In use, the annulus sizer is placed in the aorta to pass through the annulus in the heart at the site of the excised natural valve, so that the attending physician will be able to recognize the largest permissible size for the supra-annular heart valve. A set of sizers is supplied corresponding to the different sizes of available heart valves.
