Zusammenfassung:	Anatomical orifice sizers that are optimally proportional to an associated prosthetic device such as a heart valve, and methods of use are provided. The sizers are desirably slightly larger than the rigid mounting diameter of the corresponding heart valve. The heart valve sizer may be cylindrical and have a diameter about 0.3 mm larger than the valve mounting diameter. The sizer preferably has a length of between about 19 mm to 22 mm, and the edges are desirably rounded to a minimum 1 mm radius. The method includes providing a set of cylindrical sizers having varying diameters; sequentially inserting at least two of the sizers through the annulus; measuring the push force needed to pass each sizer through the annulus; selecting a valve corresponding to the sizer for which the measured push force is between about 150 and 300 grams.
