Drug delivery stent
First Claim
1. A drug delivery stent assembly including a hollow tubular metal 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 of placement in a vessel where the stent is placed and said stent being constructed in a manner which permits said stent to be placed in one of two states, one state being where said stent assumes the shape of an enlarged generally cylindrical envelope and the other state being where said stent assumes the share of a contracted smaller cylindrical envelope.

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.

14. A drug delivery stent assembly including 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 of placement in a vessel where the stent is placed and said stent being made of tantalum.
- 15. A drug delivery stent assembly including a hollow tubular metal wire stent which extends in a path defining a generally cylindrical envelope, which has a proximal end and which has side walls facing outwardly of the cylindrical envelope with holes therein for delivery of liquid to a site of placement in a vessel where the stent is placed, means for coupling and uncoupling said proximal end to a liquid delivery tubing and said stent being constructed in a manner which permits said stent to be placed in one of two states, one state being where said stent assumes the shape of an enlarged generally cylindrical envelope and the other state being where said stent assumes the shape of a contracted smaller cylindrical envelope.
- 17. A drug delivery stent assembly including a hollow tubular metal wire stent which has a proximal end, 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 of placement in a vessel where the stent is placed, means for coupling and uncoupling said proximal end to a liquid delivery tubing and said stent being made of a material which can be caused to assume two states, one state being where said stent assumes the shape of an enlarged cylindrical envelope and the other state being where said stent assumes the shape of a contracted smaller cylindrical envelope.
- 19. A drug delivery stent assembly including a hollow tubular wire stent which has a proximal end, 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 of placement in a vessel where the stent is placed, means for coupling and uncoupling said proximal end to a liquid delivery tubing and said stent being made of a nickel titanium alloy.
- 21. A drug delivery stent assembly including a hollow tubular wire stent which has a proximal end, 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 of placement in a vessel where the stent is placed, means for coupling and uncoupling said proximal end to a liquid delivery tubing and said stent being made of stainless steel.
