Abstract
A stent made of nitinol having improved axial or radial stiffness, the stent having a support structure which comprises peripheral struts around the circumference, wherein the peripheral struts are linked to one another in the axial direction via connection struts. The support structure may assume a first compressed state and a second expanded state. The nitinol is in the support structure in a martensitic microstructure in the compressed state and largely in an austenitic microstructure in the second expanded state. One or more support structure sections, however, are entirely or partially in a martensitic microstructure in the second expanded state.
