Abstract
A stent includes a series of helical windings defining an outer circumference of a cylinder. The helical windings include a plurality of struts having straight portions connected by curved portions. The straight portions may be substantially aligned with a longitudinal axis of the stent when the stent is in a reduced state. A plurality of bridges connect adjacent windings. The bridges may be substantially orthogonal to the longitudinal axis of the stent in the reduced state. A plurality of radiopaque members extend from a terminal helical winding. The radiopaque members include an extension portion and an end portion. The extension portion may have a first width and the end portion may have a second width greater than the first width. The end portion may include an extreme end substantially orthogonal to the longitudinal axis of the stent.
