Method for delivering a liquid solution to the interior wall surface of a vessel
First Claim
1. A method for delivering a liquid solution to the interior wall surface of a blood vessel comprising:
- providing 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 blood vessel where the stent is placed on a balloon of a balloon on a wire guidewire or a balloon catheter;
placing the stent on a balloon of a balloon on a wire guidewire or a balloon catheter;
inserting the stent on said balloon to a desired site in a blood vessel;
causing the balloon to expand the stent to a larger cylindrical shape; and
,supplying liquid with a liquid supply means to the stent prior to or after inserting the stent so that liquid can be delivered from the outer holes in the stent to the site of the stent in the blood vessel.

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. The method for delivering a liquid solution to the interior wall surface of a vessel using the hollow tubular wire stent comprises: placing the stent on a balloon of a balloon on a wire guidewire or on a balloon catheter; inserting the stent on the balloon assembly at a desired site in a vessel; causing the balloon to expand the stent to a larger cylindrical shape; supplying liquid with a liquid supply source to the stent prior to or after placement of the stent so that liquid can be delivered from the outer holes in the stent to the site of placement of the stent in a vessel; disengaging the liquid supply source from the stent prior to or after placement of the stent in a vessel; and allowing the liquid solution to leak from the stent through the outwardly facing holes in the stent.
