APPARATUS AND METHODS FOR LOCATING AN OSTIUM OF A VESSEL

摘要

A stent is provided for deployment into an ostium communicating from a main vessel to a branch vessel. The stent includes a first tubular portion advanceable into the ostium that is expandable from a contracted condition to an expanded condition for dilating a lesion within the ostium. The stent includes a second tubular portion that may be flared radially outwardly to contact the ostium. The stent may be carried on a delivery apparatus including an actuator for expanding the second tubular portion, and one or more balloons for expanding the first distal portion and/or further expanding the proximal portion.
