Abstract: A first aspect of the present invention is an ostial stent positioner that has the form of a wire for most of its length and having a cylinder with expandable legs situated at the positioner's distal end. The cylinder with its attached wire acts as an introducer sheath to introduce a stent delivery system with a stent into the artery that is to be stented. A second aspect of the present invention is a method for accurately placing a stent at the ostium of an artery that would have an ostial stenosis. Examples of such arteries that have ostial stenoses are the right and left main coronary arteries, a saphenous vein graft as used in coronary bypass surgery and the renal arteries. Each of these arteries has an ostium situated at the aorta.
