Abstract
A sheathed tubular semi-rigid balloon catheter for performing probing, irrigation, dilation, suction and potential intubation of the nasolacrimal system or paranasal sinus system to treat for stenosis or obstruction. The catheter includes a sheathed tubular probe portion through which a tracer fluid can be injected and through which suctioning of blood or other material can be conducted. The sheath portion of the device can have a distal segment that is inflated in order to dilate parts the nasolacrimal or paranasal sinus system. The high axial load accommodating catheter tool includes a more secure and inexpensively manufactured bond between the metallic semi-rigid tube of the probe portion and the plastic hand-manipulable, multi-connector hub using an enlarged bonding collar.
