20090138066 | Implant Deployment Apparatus - A delivery system including a restraining member maintains a collapsed implant in its collapsed state for delivery through a small passageway to a desired site in a mammalian body. Once the implant is positioned at the desired site, the restraining member is released so that the stent may expand or be expanded to its expanded state. In a preferred embodiment, the restraining member comprises a sheet of material that surrounds at least a portion of the collapsed stent. Portions of the restraining member are releasably coupled to one another with a low profile thread-like member or suture. | 05-28-2009 |

Delivery apparatus including elongate tubular members as well as shapeable distal portions and atraumatic tips are provided. Also provided are sinus penetrator devices and systems for performing ethmoidotomy procedures or for creating other openings in the walls of paranasal sinuses or other anatomical structures. | 08-06-2009 |
20100145434 | KINK RESISTANT BIFURCATED PROSTHESIS - The invention relates to an endoluminal prosthesis adapted for placement at a bifurcation site within the body. The stent or stent-graft may be constructed to have segments of differing structural properties. A section of the stent-graft may be constructed to have a single-lumen tubular stent member covering a multilumen graft member. The stent-graft may comprise at least two modular components adapted for in situ assembly. An extended cylindrical interference fit may be used to seal the modular components. | 06-10-2010 |
20100168511 | SYSTEM AND METHOD FOR DILATING AN AIRWAY STENOSIS - A method for dilating a stenotic region in an airway of a patient may include advancing a balloon catheter through the airway of the patient to position an inflatable balloon of the catheter within at least a portion of the stenotic region, maintaining a position of the catheter relative to the patient, and inflating the balloon of the catheter to dilate the stenotic region of the airway. A system for dilating a stenotic region in an airway of a patient may include a catheter shaft having an overall length of less than 70 cm, an inflatable balloon disposed along a distal portion of the catheter shaft, and a stylet. | 07-01-2010 |
20110112512 | DEVICES AND METHODS FOR TREATING MAXILLARY SINUS DISEASE - Devices and methods are described for improving drainage and/or aeration of maxillary sinuses and for treating maxillary sinus disease. Spacer devices are implanted through natural or man-made openings in the maxillary sinus. In some embodiments, the spacer device is loaded with a therapeutic substance which then exits the device over a desired time period to treat maxillary sinus disease. | 05-12-2011 |
20130184568 | DEVICE AND METHOD FOR DILATING AN AIRWAY STENOSIS - A medical device and a system and for dilating a stenotic airway of a patient are described. The medical device comprises a proximal end, a distal end, and a shaft system having an inflation lumen and a ventilation lumen the proximal end. The shaft system has a proximal shaft section and a distal shaft section. An inflatable balloon is attached to the distal shaft section in a position that is proximal to the distal end. The ventilating tip is distal to the balloon on the distal shaft section and has one or more radially facing openings. A method for treating a stenotic airway includes inserting the medical device into a patient's airway, and dilating and ventilating the airway. | 07-18-2013 |
20130245608 | IMPLANTABLE DEVICES AND METHODS FOR TREATING SINUSITIS AND OTHER DISORDERS - Devices, systems and methods for stenting, spacing, draining, ventilating and/or delivering drugs and other therapeutic or diagnostic substances to desired locations within the bodies of human or non-human animal subjects, including methods and systems for treating paranasal sinusitis and ethmoid disease. | 09-19-2013 |
20130274715 | Method and System for Eustachian Tube Dilation - A device and method for dilating a Eustachian tube of a patient is disclosed. The device includes a guide catheter and a balloon dilation catheter. The balloon dilation catheter has an actuator that prevents injury to the middle ear. The balloon dilation catheter is slidably coupled with the guide catheter through the guide catheter lumen and is fully inserted into the guide catheter lumen when the distal side of the actuator is adjacent to the proximal end of the guide catheter. The method involves advancing the guide catheter and balloon dilation catheter through a nasal passage of the patient to dilate a portion of the Eustachian tube. | 10-17-2013 |
20140074218 | IMPLANT DEPLOYMENT APPARATUS - A delivery system including a restraining member maintains a collapsed implant in its collapsed state for delivery through a small passageway to a desired site in a mammalian body. Once the implant is positioned at the desired site, the restraining member is released so that the stent may expand or be expanded to its expanded state. In a preferred embodiment, the restraining member comprises a sheet of material that surrounds at least a portion of the collapsed stent. Portions of the restraining member are releasably coupled to one another with a low profile thread-like member or suture. | 03-13-2014 |
20140277059 | APPARATUS FOR PUNCTURING BALLOON IN AIRWAY DILATION SHAFT - A dilation system includes a balloon catheter and a puncturing assembly. The balloon catheter includes a shaft, a dilator coupled to a distal end of the shaft, and a lumen extending through the shaft and the dilator. The dilator is expandable from a collapsed state to an expanded state. The puncturing assembly includes at least one cutting member. The puncturing assembly is positionable within the lumen of the balloon catheter or along an exterior of the shaft when the puncturing assembly is in a first position. The puncturing assembly transitions to a second position to puncture the lumen of the balloon catheter and/or to puncture the dilator, to thereby drain fluid from the dilator. | 09-18-2014 |
