| abstract |
Apparatus and methods are provided for locating an interventional device relative to the ostium of a branch vessel wherein an ostial locator wire is attached to the interventional device so that a selectively deployable expandable section of the ostial locator wire encircles the interventional device. A diameter of the expandable section of the distal region is larger than the diameter of the ostium of the branch vessel, so that the expandable section flattens out as it is urged into contact with tissue surrounding the ostium of the branch vessel. |
