INTRAVASCULAR STENT CONSISTS OF STAIRSTEP EXPANSION STRUT PAIRS AND DOUBLE STAIRSTEP DIAGONAL CONNECTING STRUTS CONTRALATERALLY EXTENDED FROM EXPANSION STRUTS

摘要

An intra-coronary stent (10) provides intraluminal-scaffolding support of a vascular wall after percutaneous angioplasty in which a balloon catheter is used to expand a stenotic vascular lesion. The flexible stent (10) substantially fully covers a vessel surface inside a vascular lumen. The improved stent easily delivers a delivery balloon to a selected vascular lumen site. The flexible stent has a smooth surface and sufficient radiopacity in the delivery and post delivery phase.
