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 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 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.
