摘要:
Disclosed is a stent with a highly flexible structure that is configured to provide an elevated degree of vessel scaffolding and to absorb torque applied on the stent. The stent may include an essentially tubular body formed by a web structure that is composed of a plurality of longitudinally adjacent web rings, each including a plurality of web elements that are disposed circumferentially around the longitudinal axis of the stent and that are adjoined one to the other by a junction bend. Each junction bend in a first web ring is coupled to another junction bend in a neighboring ring by a connector having a step-wise configuration, in which a central segment of the connector is disposed essentially parallel to the longitudinal axis of the stent and may become twisted to absorb torque imposed on the stent.
