The heart valve prosthesis at the support frame to the node commissure frameless type relates to medical engineering and can be used to create new designs of artificial prosthetic heart valve obturator element from a biological or synthetic fabrics used in cardiovascular surgery to replace diseased natural valves, or before implanted prosthetic heart valve in violation of their functions. A distinctive feature of the proposed prosthetic device node commissure "free type" is a combination of the reference frame in the prosthesis with flexible flaps with node commissure frameless type. prosthetic device has resilient strut, at least two, in which in duplikatury inner cladding formed commissure when fixing seam formed atraumatic suture material, two adjacent slats, and the seam is located between the outer and inner skin partial frames, so that seams are absent both the valve lumen and the outside. The utility model provides improved hemodynamic characteristics to values close to the natural human valve, more adequate correction of heart valve defect in the postoperative period with regression of myocardial hypertrophy, reduction of dynamic loads on the wing in the region commissures and extended life functional viability of the prosthesis in the body of the recipient. 2 yl.
