ABSTRACT:
A dilatation catheter having an inflatable member and a method of using same to restore patency to an obstructed portion of the lacrimal system. The catheter is inserted into the lacrimal system and its inflatable member is positioned in the obstructed portion. The inflatable member is inflated to dilate the obstructed portion to restore patency to the lacrimal system. Preferably, the catheter includes one or more visually perceivable markers having a known spaced relationship to one of the ends of the inflatable member. Positioning of the inflatable member is assisted by aligning the marker relative to an opening into the lacrimal system.
