Patent Images
1. A stent for insertion into a vessel of a patient, said stent adapted to receive a marker element, comprising:
- a tubular member having a first smaller diameter configuration for insertion into the vessel, and a second larger diameter configuration for deployment within the vessel, said tubular member including two ends, at least one of said ends including at least one marker mount extending therefrom, each said marker mount including a pair of fingers, at least one of the fingers having an enlarged retainer portion, and at least one of said fingers of said pair of fingers adapted to be moved relative to the other of said fingers of said pair of fingers to receive a marker over said pair of fingers.

Abstract
A stent includes a marker mount defined by a pair of fingers. The fingers are preferably oriented parallel to the longitudinal axis of the stent. The fingers preferably each include a retainer at their respective ends, and the retainers of each pair of fingers preferably define a composite barb. A tubular marker can be forced over the bifurcated barb and onto the fingers. The marker is preferably provided with a ceramic coating to prevent galvanic corrosion between the stent and the marker.
