1. A method for stenting a body passageway, the method comprising:
- locating a distal end of a first guidewire at a site within the body passageway;
feeding a delivery catheter over the first guidewire, said delivery catheter having a catheter body including a lumen, a compressed superelastic stent slidably compressed in the lumen, and means to maintain at least a far end of the stent in an open configuration when the stent is compressed and in said lumen and prior to insertion of the first guidewire in the stent while feeding the delivery catheter over the first guidewire;
