Abstract
A stent delivery system includes a core member and a coupling assembly rotatably coupled to the core member distal segment. The coupling assembly includes first and second plates and first and second spacers. The first plate is rotatably coupled to the core member and includes an outer surface having three or more projections separated by recesses. The first spacer is coupled to the core member and disposed between the first plate and a proximal restraint. The second plate is rotatably coupled to the core member and includes an outer surface having three or more projections separated by recesses. The second spacer is coupled to the core member and disposed between the first plate and the second plate. A stent extends along the core member distal segment such that an inner surface of the stent is engaged by one or more projections of the first plate or the second plate.
