Abstract
Apparatus and methods are provided for delivering a stent into an ostium. The apparatus includes a catheter including a proximal end, a distal end, and proximal and distal balloons disposed adjacent one another on the distal end. The balloons are expandable independently of one another, and a stent is provided surrounding the balloons. During use, the distal end of the catheter is introduced into a main lumen, and the proximal balloon is inflated to flare a proximal portion of the stent. The distal end is then advanced into the ostium until the flared proximal portion contacts a wall of the main lumen surrounding the ostium. The distal balloon is inflated to expand a distal portion of the stent, e.g., to dilate a lesion within the branch and/or ostium. Thereafter, the balloons are collapsed, and the apparatus is withdrawn, leaving the stent within the ostium.
