Abstract:
A vascular stent (100) comprises a plurality of wave loops. In its natural state, in two of the wave loops which are adjacent in a group, a part of a wave crest of a lower layer wave loop are in a restrained connection with a part of a wave trough of an upper layer wave loop; the other part of the wave crest of the lower layer wave loop passes through the other part of the wave trough of the upper layer wave loop, and the other part of the wave crest and the other part of the wave trough are in a non-contact mutually-suspended connection. Some of the wave crests and wave troughs of the vascular stent (100) are in the non-contact mutually-suspended connection rather than the restrained connection, so that the maximum flexibility is provided to the stent, and meanwhile, the overall stability of the stent is guaranteed. The stent (100) can maintain a good shape during both implantation and the release process, so that safety during release is ensured.
