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 Thereafter, the balloons are collapsed, and the apparatus is withdrawn, leaving the stent within the ostium.

Abstract: Vascular embolic filtering devices and systems, as well as methods for using the same, are provided. The embolic filtering device includes a guide wire and an associated embolic filter for capturing emboli created during interventional procedures within a target vessel. Features of the subject devices and system provide for delivering of the guide wire independently of the filter, rotating of the guide wire with respect to the filter and limiting or preventing the proximal translation of the filter with respect to the guide wire. The embolic filter is attached to a sheath having either a shorter-length configuration or an extended-length configuration. The guide wire comprises a proximal stop mechanism engageable with the sheath to limit at least the proximal translation of the embolic filter. The subject embolic filter systems provide such guide wires and embolic filters, as well as and an embolic filter delivery, deployment and removal assembly.
