FRAME FOR BIOLOGICAL CARDIAC VALVE PROSTHESIS

摘要

FIELD: medicine.SUBSTANCE: invention refers to medical equipment and can be used for the replacement of involved natural human cardiac valves. A frame for a biological cardiac valve prosthesis comprises a tubular insert 2, which bears a flexible element 5 having flexible supports 6, each of which comprises two flexible beams 7. Each flexible beam 7 is provided with a loop-shaped element 16 positioned on heads 8 of the flexible beams 7 and coupling support stands 9 and bridges 13 mounted between two support stands 9 of the flexible element 5 from different flexible supports 6; each loop-shaped element 16 is provided with a seating surface 17 facing the vertical plane 11 passing through the central axis 12 of the frame; the support stands are mounted in relation to the above vertical plane 11; the seating surface 17 lies in a plane extending in parallel through the central axis of the frame with the support stands 9 being mounted symmetrically in relation to the vertical plane 11. The seating surfaces 17 of two flexible beams 7 from the same flexible support 6 are configured symmetrically in relation to the plane 11 passing through the central axis 12 of the frame.EFFECT: increasing the reliability by reducing a rate of potential cusp cutting-through by fastening threads.3 cl, 5 dwg
