| 20080208242 | Method for treating naturally obstructed paranasal sinuses - A set of sinus balloon catheters are provided for treating a patient's naturally obstructed paranasal sinus system, including dilating prepared openings, and natural ostia and ducts and excising sinus cavities. These include a balloon catheter with a bend placing a distal segment at 90 degrees to a proximal segment and a balloon catheter which is substantially straight. The catheters have sufficient stiffness and column strength that the balloon carrying distal segment of the catheter can be pushed into the prepared opening, natural ostium or duct, or sinus to be excised. The catheters have appropriate inflated working diameters and appropriate outer diameters with the balloon deflated that will enable the catheter to be pushed into the respective prepared opening, natural ostium or duct, or sinus cavity to be excised. The methods use the balloon catheters to dilate prepared openings to selected parts of the sinus system, to dilate natural ostia and ducts of the sinus system, and/or to dilate sinus cavities to remove them. | 08-28-2008 |
| 20080208243 | Method for treating obstructed paranasal ethmoid sinuses - A set of sinus balloon catheters are provided for treating a patient's paranasal ethmoid sinus system, including dilating prepared openings, and natural ostia and ducts and excising sinus cavities.

| 20090281621 | Punctal anchor for lacrimal stent, introducer tool and method - A device and method for performing stenting and intubation of the nasolacrimal system to treat for stenosis or obstruction includes a semi-rigid tubular guide sleeve through which a flexible tubular stent, having an oversized length, is inserted from a punctal opening into the nasal cavity. The guide sleeve is removed and a resilient, radially expandable punctal anchor is placed through the punctal opening, to contact the stent and hold it in place. An introducer device having a hollow tubular core and a coaxially mounted, axially translatable outer sheath is provided to facilitate placement of the anchor. The anchor is stretched over the distal end of the core and the stent threaded into the central lumen of the core. Once the anchor is in place, the sheath is translated to push the anchor off the distal end. Excess stent at its proximal end is then trimmed off. | 11-12-2009 |
| 20100179468 | Side-by-side lacrimal intubation threader and method - A device to facilitate insertion or threading of a flexible silicone intubation stent into the lacrimal drainage system of a patient. The device has an oblong hollow semi-rigid probe having the flexible stent releasably secured to its blunted distal end. The probe and stent are oriented in a side-by-side configuration and inserted endwise through the punctal opening, down through the nasolacrimal duct and into the nasal cavity. The flexible stent is detached from the distal end of the probe, and the probe withdrawn, leaving the stent in place. The flexible stent can be temporarily secured to the distal end of the probe through a number of means. One preferred way is to friction fit a resilient distal aperture of the stent upon the distal end of the probe and occlude the probe's distal opening. The stent is detached by injecting a pressurized fluid through the channel of the probe thereby forcing the distal end of the stent to pop off. The proximal extremity of the stent is secured in the patient by an integrated or separate punctal anchor. | 07-15-2010 |
