NASOLACRIMAL SYSTEM SURGICAL TOOL AND METHOD
First Claim
1. A device for the treatment of a patient'"'"'s canaliculus and nasolacrimal duct stenosis which comprises:
- a tube shaped and dimensioned to penetrate said canaliculus and duct;
said tube being made of a substantially hard material, and having a proximal end, a blunted distal end, an axial lumen, a total length between approximately 4 and 50 centimeters and an outer diameter between 0.125 and 4.00 millimeters;
a connector at said proximal end;
said lumen having at least one orifice at said distal end.

Abstract
A device and method for performing probing, irrigation, suction and intubation of the nasolacrimal system to treat for stenosis or obstruction includes a tubular probe (47) 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 (43) fitted over the probe has distal segment (44) that is inflated in order to retain the sleeve in the nasolacrimal system once the tubular probe has been withdrawn.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. An alternate embodiment provides a tool combining two elongated conduits, one of which is terminated at a distal end by an inflatable balloon. The other conduit is used for either “irrigating or suctioning. The tool is particularly useful to perform dacryocystoplasty (DCP) and dacryocystorhinostomy (DCR).
