A vascular implant for implanting into a blood vessel of a patient, the vascular implant being transformable from a compressed state into a self-expanded state, the vascular implant comprising:
- a hollow-cylindrical main body with a proximal end and a distal end, the hollow-cylindrical main body defining a main body lumen and a longitudinal axis;
- at least one hollow-cylindrical side body that branches off from the main body and comprises a side body lumen and a side body implant material, the side body lumen being in fluidic connection with the main body lumen;
- a plurality of stent springs successively arranged over the longitudinal axis of the main body, the plurality of stent springs including a first stent spring, a second stent spring, and a protruding stent spring;
- an implant material fixed to the plurality of stent springs and connecting them, the stent springs being connected to one another via the implant material only and not connected by any other means between adjacent springs,
- wherein the first stent spring, the second stent spring, and the protruding stent spring each have a plurality of legs and pointed arches, the pointed arches being defined by respective adjacent legs and a vertex or depression between the respective adjacent legs such that the pointed arches of the first and the second stent springs alternately face toward the proximal end and the distal end of the main body and parallel to the longitudinal axis thereof,
- wherein at least three consecutive legs of each of the first stent spring, the second stent spring, and the protruding stent spring have different lengths, the at least three consecutive legs connecting a first vertex, a first depression following the first vertex in a circumferential direction, a second vertex following the first depression in the circumferential direction, and a second depression following the second vertex in the circumferential direction,
- wherein respective vertices of the first stent spring are aligned circumferentially with respective depressions of the second stent spring and respective depressions of the first stent spring are aligned circumferentially with respective vertices of the second stent spring,
- wherein the first stent spring, the second stent spring, and the protruding stent spring have an asymmetrical shape in which successive vertices have different heights in the proximal direction along the longitudinal axis and successive depressions have different depths in the distal direction along the longitudinal axis,
- wherein the vertices of the first stent spring, the second stent spring, and the protruding stent spring include at least one maximum-height vertex that has a maximum height of respective vertices and the depressions of the first stent spring, the second stent spring, and the protruding stent spring include at least one maximum-depth depression that has a maximum depth of respective depressions,
- wherein, in the self-expanded state, the at least one side body branching off from the main body is set up at an angle in relation to the longitudinal axis of the main body, the angle being defined by at least one pointed arch of the protruding stent spring of the main body, the at least one pointed arch angularly protruding in a preformed way in relation to the longitudinal axis of the main body in the self-expanded state, and
- wherein the at least one pointed arch is formed by one of the at least one maximum-depth depressions of the protruding stent spring.
