| 摘要 |
The invention relates to a self-expanding vascular implant for implanting into a blood vessel, the implant comprising a hollow cylindrical body with a proximal and a distal end and with a longitudinal axis; comprising stent springs, which are successively arranged and spaced from one another over the longitudinal axis of the body, each stent spring meandering; and comprising an implant material, which is fixed to the stent springs and connects same. The stent springs have pointed arches which alternately point toward the proximal and distal direction and comprise alternating crests and troughs that are connected to one another via legs of different lengths, whereby a stent spring has pointed arches, which are circumferentially and successively arranged and which have different heights, said pointed arches consisting of higher and shorter pointed arches. |

1. A self-expanding vascular implant for implanting into a blood vessel, the vascular implant comprising a hollow-cylindrical body with a proximal end and a distal end and a longitudinal axis, and also comprising stent springs, which are successively arranged at a distance over its longitudinal axis and which circumferentially meander, respectively, and comprising an implant material fixed to the stent springs and connecting them, the stent springs being connected by way of the implant material only and not between one another, and the circumferential stent springs having pointed arches facing alternately toward the proximal direction (x) and the distal direction (y), which are connected to one another by way of legs, wherein at least two stent springs successively arranged in the longitudinal direction, respectively, have legs of different lengths for forming of circumferentially arranged pointed arches of varying height, with higher and shorter pointed arches, and in that a higher pointed arch facing toward the proximal direction x of a first stent spring lies opposite a shorter pointed arch facing toward the distal direction y, of a second stent spring arranged proximally thereafter, at a distance and at an imaginary line that is parallel to the longitudinal axis of the vascular implant, and/or in that a shorter pointed arch facing toward the proximal direction x, of a first stent spring lies opposite a longer pointed arch facing toward the distal direction y of a second stent spring arranged thereafter in the proximal direction x, at a distance and at an imaginary line (A) that is parallel to the longitudinal axis of the vascular implant. |
