A LOW PROFILE BALLOON EXPANDABLE ARTIFICIAL PROSTHETIC HEART VALVE, PARTICULARLY AORTIC, FOR TRANSCATHETER IMPLANTATION

摘要

A low profile balloon expandable artificial prosthetic heart valve, particularly aortic, for transcatheter implantation comprises a valve frame of cylindrical structure. The cuff made of the polymer material is inseparably integrated with the frame so that the valve frame in the supporting section is embedded or sewn into and covered from the internal side and from the outside with the cuff material, which folded into the interior section of the frame and in the frame valve section is formed into valve leaflets in bicuspid or tricuspid configuration and in the said section it is attached to the frame and to the frame posts, and the cuff material excess is led into the longitudinal openings in the posts. In the variant of mounting the cuff made of the polymer (artificial) material is attached to the frame in the supporting section from the outside and the cuff material is folded into the interior of the frame, and in the frame valve section it creates leaflets and commissures of the valve in bicuspid or tricuspid configuration and in this section it is attached to the frame and to the posts by sewing, and the excess of the cuff material is led into the longitudinal openings in the posts.
