<p>Improved sizers and markers (100) include a cylindrical section (102) and a handle (106) extending from the cylindrical section (102). The cylindrical section (102) has a diameter approximately equal to the diameter of an aortic heart valve prosthesis (160). The cylindrical section (102) can include a marking element (206), (292), (330), (350) configured to mark tissue at fixed positions relative to the cylindrical section (102). Marking can be performed with a variety of techniques.</p> |
