WIDTH-ADJUSTABLE CUTTING INSTRUMENT FOR TRANSAPICAL AORTIC VALVE RESECTIONING

摘要

A surgical cutting instrument for transapical aortic valve resection includes a cutting unit arranged on the distal end of a tool shaft and at least one mechanical cutting element for making a circular incision. The at least one cutting element can be adapted, in particular continuously adapted to different aortic diameters by means of a radially movable actuating mechanism.
