摘要：
1. A valve replacement device for transcatheter implantation, comprising: a stent component having an edge for the delivering flow and an edge for the outgoing flow and configured to radially compress in a compressed state for delivery to the implantation site and expand into a functional state, the flaps valves installed at least partially inside the stent component, characterized in that it contains an inner skirt fixed to the valve flaps and passing at least h -particle within stent component towards the edge for bringing the flow outer skirt extending at least partially outside of stent component farther than the internal skirt, towards the edge for bringing potoka.2. The device according to claim 1, characterized in that the inner skirt and outer skirt partially overlap in the axial direction. A device according to one of claims 1 or 2, characterized in that the inner skirt extends farther than the outer skirt towards the edge for the outflow of the stent component. 4. A device according to one of claims 1 or 2, characterized in that the neck of the stent component has a zigzag shape in the form of a lattice structure of at least one row of cells formed by an alternating sequence of free vertices at the edge for the bringing flow and connected vertices attached to adjacent cells, the inner skirt extending only to a level corresponding to at least some of the connected vertices, and the outer skirt extending to a level corresponding to at least some ofУстройство для замены клапана содержит клапанный компонент, имеющий по меньшей мере две створки клапана, предпочтительно изготовленные из ткани перикарда. Каждая створка клапана включает в себя по меньшей мере два язычка. Устройство, кроме того, включает в себя стентовый компонент, предназначенный для радиального сжатия в сжатое состояние и способный расширяться в функциональное состояние. Стентовый компонент содержит первый конец, второй конец и по меньшей мере одну промежуточную секцию, расположенную между вышеуп
