Abstract: An intravascular stent comprising a cylindrical body capable of expansion having end assemblies capable of locking in an expanded state. The end assemblies may have a series of tabs and apertures that interlock and rotate as the stent ends expand to an open position to support a section of vasculature or other body lumen. The stent is bio-compatible, may be bio-erodible, and capable of localized drug delivery.

Abstract: A method and apparatus for repairing a vessel at a bifurcation without obstructing blood flow through the bifurcation, wherein an expandable ostial stent comprises a tubular body and a deformable flaring portion. Repair of a bifurcated vessel is accomplished by positioning the expandable ostial stent within a diseased portion of the bifurcation so that the flaring portion caps the ostium and the tubular body is seated within a side branch to the bifurcation, thereby completely repairing the vessel at the bifurcation without occluding blood flow.
