ABSTRACT:
A flexible stent is provided that has features to minimize recoil and facilitate anchoring of the stent in a vascular passage. The design features sharp angulated bends. Other features include a rounded cross-section in the wire or stent components. Another feature is the bending of the angulated bends in a transverse plane to provide additional rigidity and an anchoring mechanism. Ties are provided in alignment or in staggered fashion, either semi-rigid or flexible, to allow the structure, which can be made of joined rings or a helical arrangement, to be more flexible to accommodate bends in the vascular system. The ties are also disclosed with a locking system involving bending the wire as it is formed into a helix in combination with crossties with loops which lock the stent in an expanded position.
