Abstract
An expandable stent is provided. The stent has a ring architecture in which a plurality of connector segments join a plurality of ring structures to form the stent. The ring structures are an endless pattern of unit structures, each of which has two lateral arms and a central portion, and is inverted with respect to the immediately adjacent unit structures of the same ring structure. The connector segments have an undulating portion and are preferably axially displaced relative to other, circumferentially adjacent connector segments when the stent is in an unexpanded configuration. A delivery system that includes a stent accordingly to the present invention is also provided.
