Claims (9)

1. Intraluminale Vorrichtung, umfassend einen radial aufweitbaren, rohrförmigen Stent mit innen- und außenliegenden Oberflächen, welche sich in Richtung der Längsachse des Stents erstrecken; und eine Stentbedeckung, wobei die Stentbedeckung rings um den Stent angeordnet ist, aus einem im Wesentlichen eindimensional gerichteten Polymer hergestellt ist, in einer ersten Richtung gerichtet und in einer zweiten Richtung quer zur ersten gestreckt ist, wobei die Länge der Stentbedeckung gegenüber der ursprünglichen Länge geringer wurde, und die Längsachse des Stents mit der zweiten Richtung ausgerichtet ist, so dass bei einer radialen Aufweitung des Stents die Stentbedeckung in der ersten Richtung in der ursprünglichen Länge dehnbar ist und die radiale Aufweitung des Stents begrenzt.1. Intraluminal device comprising a radially expandable, tubular stent internal and external surfaces, which are in Extend in the direction of the longitudinal axis of the stent; and a stent cover, the stent cover being ringed is essentially arranged around the stent one-dimensionally directed polymer is produced in directed in a first direction and in a second Direction is stretched across the first, the length the stent coverage versus the original length became smaller, and the longitudinal axis of the stent with the second direction is aligned, so that at a radial expansion of the stent covering the stent in stretchable in the original direction in the first direction and limits the radial expansion of the stent. 2. Intraluminale Vorrichtung nach Anspruch 1, wobei der Stent von einem zusammengedrückten Zustand, in dem ein intraluminales Anbringen möglich ist, in einen zweiten, aufgeweiteten Zustand, der ein intraluminales Einsetzen erlaubt, aufgeweitet werden kann.2. Intraluminal device according to claim 1, wherein the Stent from a compressed state in which a intraluminal attachment is possible in a second, widened state, which is an intraluminal onset allowed, can be expanded. 3. Intraluminale Vorrichtung nach Anspruch 1 oder 2, wobei die gestreckte Stentbedeckung in der ersten Richtung bis zur ursprünglichen Länge dehnbar ist.3. Intraluminal device according to claim 1 or 2, wherein the stretched stent covering in the first direction is stretchable to the original length. 4. Intraluminale Vorrichtung nach irgendeinem vorhergehenden Anspruch, wobei das eindimensional gerichtete Polymer ungesintertes ePTFE enthält. 4. Intraluminal device after any previous Claim, wherein the one-dimensionally directed polymer contains unsintered ePTFE.   5. Intraluminale Vorrichtung nach irgendeinem vorhergehenden Anspruch, wobei die Stentbedeckung aus einem Längssegment aus ungesintertem ePTFE besteht.5. Intraluminal device after any previous Claim, wherein the stent cover from a longitudinal segment consists of unsintered ePTFE. 6. Intraluminale Vorrichtung nach irgendeinem vorhergehenden Anspruch, wobei ein Längssegment um den Stent herum ange­ ordnet ist und an einer Naht, die von aufeinanderstoßenden überlappenden Kanten des Segments gebildet wird, zusammen­ gefügt ist.6. Intraluminal device according to any previous Claim, wherein a longitudinal segment around the stent is attached is arranged and on a seam that by abutting overlapping edges of the segment is formed together is joined. 7. Intraluminale Vorrichtung nach irgendeinem vorhergehenden Anspruch, wobei die Naht durch Zusammendrücken und Sichern überlappender Kanten gebildet ist.7. Intraluminal device after any previous Claim, wherein the seam by compressing and securing overlapping edges is formed. 8. Intraluminalvorrichtung nach irgendeinem vorhergehenden Anspruch, wobei überlappenden Kanten verklebt sind.8. Intraluminal device after any previous Claim, with overlapping edges are glued. 9. Intraluminale Vorrichtung nach irgendeinem vorhergehenden Anspruch, wobei das Segment außen um den Stent herum gewickelt ist.9. Intraluminal device according to any previous Claim, wherein the segment around the outside of the stent is wrapped.
