Abstract
A reversible, flexible, lacrimal duct occluder is formed of a shaft having a low profile cap at one end and a rounded tip at the other end. At least one, preferably 1-3, conical ranges are forward on the shaft between the ends. The rounded tip enters the punctum followed by leading edge of the range(s) until the occluder bends and enters the horizontal canalicular canal. A series of occluders having 1-3 ranges and varying lengths can be provided to accommodate the different canalicular geometries of different individuals. The occluder is readily inserted without the need to use any special introducer tool and is easily removed from the canaliculus of the patient.
