Abstract
Zgłoszenie opisuje stent zastawki aortalnej, który jest samorozprężalny a także repozycjonowalny i wykonany jest korzystnie z nitynolu. Składa się on z dwóch części: części górnej oraz części dolnej. Część dolną stanowi siatka (1) rozmieszczona tak, że tworzy niejako ścianę walca na całej wysokości tego elementu. Dopuszczalny jest także inny kształt siatki, np. częściowo stożkowaty, względnie częściowo przypominający spłaszczoną ścianę boczną walca. Natomiast część górną stentu stanowią wyprowadzone z siatki (1) w górę i rozmieszczone w równych odstępach trzy ramiona (2), których wysokość jest nieco większa niż wysokość siatki (1), nieco mniejsza niż wysokość siatki (1) albo równa jej wysokości. Ramiona (2) stentu ukształtowane są w taki sposób, że tworzą razem niejako obrys obłej czaszy kielicha, a ich końcowa, peryferyjna część korzystnie jest prosta i także nachylona do środka. Przestrzeń pomiędzy ramionami (2) zawsze zapewnia swobodny dostęp do tętnic wieńcowych. Na końcu każdego z ramion (2) umieszczony jest górny znacznik (3) zastawki, a każdemu górnemu znacznikowi (3) odpowiada znacznik dolny (8), który umieszczony jest w dole siatki (1), czyli po przeciwnej stronie i pod danym ramieniem (2). Dolny znacznik (8) umożliwia precyzyjnie implantowana stentu według założonego planu.The application describes an aortic stent which is self-expanding as well as repositioningable and is preferably made of nitinol. It consists of two parts: the upper part and the lower part. The lower part is a grid (1) arranged so as to form a wall of the cylinder along the entire height of this element. Another shape of the net, e.g. partly conical or partly resembling the flat side wall of the cylinder, is also acceptable. The upper part of the stent, on the other hand, consists of three arms (2) drawn out of the mesh (1) up and spaced at equal intervals, whose height is slightly greater than the height of the mesh (1), slightly less than the height of the mesh (1) or equal to its height. The arms (2) of the stent are shaped in such a way that together they form a contour of the round cup of the cup, and their final, peripheral part is preferably straight and also inclined inwards. The space between the arms (2) always provides free access to the coronary arteries. At the end of each arm (2) is placed the upper mark (3) of the valve, and each upper mark (3) corresponds to the lower mark (8), which is located at the bottom of the net (1), i.e. on the opposite side and under the given arm ( 2). The lower mark (8) enables precisely implanted stent according to the assumed plan.
