Изобретение относитс к медицинской технике, а именно к протезам клапанов сердца. The invention relates to medical engineering, in particular to prosthetic heart valves.

Цель и:юбретени снижение нагрузки на сердце. Purpose and: yubreteni reduce the load on the heart.

На фиг. FIG. 1 показан опорный каркас протеза в виде пружины; 1 shows a supporting frame of the prosthesis in the form of a spring; на фиг. FIG. 2 протез клапана, разрез. 2 valve prosthesis incision.

Протез клапана сердца содержит опорный каркас с нижним 1 и верхним 2 кольцами , которые соединены цилиндрической пружиной 3. Внутри нижнего кольца 1 находитс дополнительное укрепл ющее кольцо 4. Все элементы опорного каркаса выполнены из гибкого упругого гемосовмести- мого материала. The prosthetic heart valve comprises a support frame 1 with a lower and an upper ring 2, which are connected to the coil spring 3. Inside the lower ring 1 is further strengthened guide ring 4. All the elements of the support frame are made of flexible resilient material gemosovmesti- forward. В каркасе закреплен клапан , выполненный из биосов.местимого материала , состо щий из запорного элемента с трем створками 5 оболочки 6 с трем синусо- образными выступами и цилиндрический участок 7, в который переход т оболочки 6. Торец цилиндрического участка 7 вл етс верхним краем 8 протеза, а нижним краем 9 вл етс место креплени оболочки 6 между нижним 1 и дополнительным укрепл ющи.м 4 кольцами. The valve frame is fixed, made of biosov.mestimogo material consisting of a closure element having three flaps 5, the envelope 6 with three sinuso- shaped projections and cylindrical portion 7, which proceeds sheath 6. The end of the cylindrical portion 7 is a top edge 8 prosthesis, and the lower edge 9 is the place of attachment of the envelope 6 between the bottom 1 and the additional reinforcing yuschi.m 4 rings. Створки 5 запорного элемента расположены над кольцами 1 и 4 по линии 10 креплени створок 5 к обо.чочке 6. Причем оболочка 6 выполнена из биологического трансплантата, а его цилиндрический участок 7 выбирают длиной, равной не менее диаметра опорного каркаса. The flaps 5 of the closure element disposed above the ring 1 and 4 through line 10 to the attachment flaps 5 obo.chochke 6. Moreover envelope 6 is made of a biological graft and its cylindrical portion 7 is selected length equal to at least the diameter of the support frame.

Протез работает следующим образом. The prosthesis works as follows.
