Biological low profile, balloon expandable prosthetic heart valve, particularly aortic, for transcatheter implantation and the method of its manufacturing

A method of manufacturing a biological low-profile balloon expandable prosthetic heart valve, particularly aortic for transcatheter implantation comprising:

• providing a valve frame of design which consists of a valve section, a second section;
• and
• providing a single continuous biological material forming a cuff from an upper part of the biological material;
• attaching the material to the valve frame in the second section on the exterior of the valve frame;
• folding the cuff to the interior of the frame;
• attaching parts of the cuff to posts in the valve section, and
• forming commissures from 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;
• and using the commissures for the valve leaflets.
