The invention relates to a self-expanding vascular implant (10) for implanting into a blood vessel, comprising a hollow cylindrical body (24) with a proximal (12) and a distal end (14) and with a longitudinal direction; comprising stent springs (15, 16, 17, 18, 19, 20), which are arranged one behind the other in a mutually spaced manner in the longitudinal direction of the body and each of which circulates in a meandering manner; and comprising an implant material (22), which is fixed to the stent springs (15, 16, 17, 18, 19, 20) and connects same. The stent springs (15, 16, 17, 18, 19, 20) have pointed arches which alternately point in the proximal and distal direction and comprise alternating crests (26a, 26b, 26c) and troughs (28a, 28b, 28c) that are connected to one another via limbs (30, 31, 32, 33) of different lengths, whereby a stent spring (15, 16, 17, 18, 19, 20) has pointed arches (50, 60) which follow one another in a circulating manner and have different heights, said pointed arches consisting of taller (50a, 60a) and shorter (50b, 60b) pointed arches.
