Abstract
A device and method for performing probing and intubation of the nasolacrimal system includes a tubular probe through which a tracer fluid is injected and collected in the nasal cavity to verify that the tip of the probe has passed through an obstruction and reached the nasal cavity. A sleeve fitted over the probe has distal segment that is inflated in order to retain the sleeve in the nasolacrimal system once the tubular probe has been withdrawn. Removal of blood and other obstructions encountered during the probing or intubation process is accomplished by connecting the proximal end of the probe to a suction device.
