Claims (14)

1. Стент, состоящий из полосы спирально накрученных в ряд спиральных витков, где полоса имеет по крайней мере две боковые кромки, где каждая из по крайней мере двух боковых кромок изготавливается в форме змеевика, включающего серию изгибов, где по крайней мере две боковые кромки полосы соединяются друг с другом, и где при расширении стента, изгибы по крайней мере двух боковых кромок распрямляются с удлинением полосы в направлении спирали, чтобы позволить стенту расширятся без какого-либо значительного раскручивания полосы.1. A stent consisting of a strip of helically wound into a series of spiral turns, where the strip has at least two side edges, where each of at least two side edges is made in the form of a coil, comprising a series of bends, where at least two side edges of the strip are connected to each other, and where, as the stent expands, the bends of at least two side edges straighten with an extension of the strip in the spiral direction to allow the stent to expand without any significant unwinding of the strip. 2. Стент по п.1, где по крайней мере две боковые кромки в форме змеевика соединяются друг с другом поперечными стойками. 2. The stent according to claim 1, where at least two side edges in the form of a coil are connected to each other by transverse struts. 3. Стент по п.2, где поперечные стойки соединяют примыкающие изгибы по крайней мере на двух боковых кромках в форме змеевика. 3. The stent according to claim 2, where the transverse struts connect adjacent bends at least at two lateral edges in the form of a coil. 4. Стент по п. 3, где примыкающие изгибы, которые соединяются каждой поперечной стойкой, обращены в противоположные стороны. 4. The stent according to claim 3, where the adjacent bends, which are connected by each transverse strut, are turned in opposite directions. 5. Стент по п. 3, где поперечные стойки соединяют по крайней мере две боковые кромки в форме змеевика с периодическими интервалами, и где каждая по крайней мере из двух кромок в форме змеевика имеет по крайней мере один изгиб между последовательными поперечными стойками. 5. The stent according to claim 3, where the transverse struts connect at least two side edges in the form of a coil with periodic intervals, and where each of at least two edges in the form of a coil has at least one bend between successive transverse racks. 6. Стент по п.2, где поперечные стойки являются прямыми. 6. The stent according to claim 2, where the transverse struts are straight. 7. Стент по п.2, где поперечные стойки имеют изгибы. 7. The stent according to claim 2, where the transverse struts have bends. 8. Стент по п.2, где поперечные стойки протягиваются в основном перпендикулярно к направлению спирали, в котором полоса накручивается. 8. The stent according to claim 2, where the transverse struts extend mainly perpendicular to the direction of the spiral in which the strip is wound. 9. Стент по п. 1, где полоса имеет два конца, где по крайней мере две боковые кромки сходятся относительно друг друга на двух концах полосы, так что два конца полосы заостряются. 9. The stent according to claim 1, where the strip has two ends, where at least two side edges converge relative to each other at the two ends of the strip, so that the two ends of the strip are sharpened. 10. Стент по п.1, где полоса имеет два конца, причем первый конец полосы располагается на первом конце стента, а второй конец полосы располагается на втором конце стента, и где каждый конец полосы соединяется с примыкающем витком стента. 10. The stent according to claim 1, where the strip has two ends, the first end of the strip being located at the first end of the stent, and the second end of the strip being located at the second end of the stent, and where each end of the strip is connected to an adjacent turn of the stent. 11. Стент по п. 10, где каждый конец полосы соединяется с примыкающем витком с помощью сварки. 11. The stent according to claim 10, where each end of the strip is connected to an adjacent turn by welding. 12. Стент по п.1, где полоса изготавливается из проволоки. 12. The stent according to claim 1, where the strip is made of wire. 13. Стент по п.1, где полоса изготавливается из листового металла. 13. The stent according to claim 1, where the strip is made of sheet metal. 14. Стент по п.1, где стент создается путем изготовления полосы и затем накручивания полосы в виде спирали для получения стента. 14. The stent according to claim 1, where the stent is created by manufacturing the strip and then winding the strip in the form of a spiral to obtain a stent.
