METHOD OF FORMING PREFABRICATED UNITS USED IN PRODUCTION OF SYSTEMS OF PROSTHETIC AORTIC VALVE TRANS-CATHETER IMPLANTATION AND PROSTHETIC AORTIC VALVE PREFABRICATED UNIT

摘要

A biological low profile balloon expandable prosthetic heart valve, particularly aortic for transcatheter implantation comprising a valve frame of cylindrical design which consists of a valve section, a supporting section and a biological material sewn thereto. The upper part of the cylindrical cuff made of the biological material is attached to the valve frame in the supporting section on the outside and the cuff is folded to the interior of the frame and it is attached to the posts in the valve section. The upper parts of the cuff which are not attached to the posts, on each side of the post are connected with each other on the valve frame establishing commissures for the valve leaflets.
