ABSTRACT:
The drug delivery stent assembly includes a hollow tubular wire stent which extends in a path defining a generally cylindrical envelope and which has side walls facing outwardly of the cylindrical envelope with holes therein for delivery of liquid to a site in a vessel where the stent is placed and the stent being constructed in a manner which permits the stent to be placed in one of two states, one state being where the stent assumes the shape of an enlarged generally cylindrical envelope and the other state being where the stent assumes the shape of a contracted smaller cylindrical envelope.
