Publication number: 20170028112Abstract: A balloon dilation catheter includes a substantially rigid inner guide member and a movable shaft coupled to a balloon that is slidably mounted on the substantially rigid inner guide member. To treat a sinus cavity of a subject using the balloon dilation the substantially rigid inner guide member is advanced into a drainage pathway of the sinus (e.g., frontal recess or maxillary sinus) of the subject via a nasal passageway. The shaft and balloon are advanced in a distal direction over the substantially rigid inner guide member to place the balloon in the drainage pathway. The balloon is inflated to expand or otherwise remodel the drainage pathway.Type: ApplicationFiled: October 11, 2016Publication date: February 2, 2017Applicant: ENTELLUS MEDICAL, INC.Inventors: John R. Drontle, Anthony J. Hanson, Paul Lesch

Patent number: 9550049Abstract: A method of treating a sinus cavity of a subject includes advancing a distal portion of a light source through a drainage pathway of a sinus cavity and into the sinus cavity and visually observing a transdermal light emitted from the light source. A distal portion of a substantially rigid inner guide member of a balloon dilation catheter is advanced into the drainage pathway, the balloon dilation catheter including a movable shaft including a balloon that is slidably mounted on the substantially rigid inner guide member. The movable shaft and balloon are advanced distally over the substantially rigid inner guide member to place a portion of the balloon in the drainage pathway whereby the balloon is inflated.Type: GrantFiled: August 26, 2014Date of Patent: January 24, 2017Assignee: ENTELLUS MEDICAL, INC.Inventors: Anthony J.

Publication number: 20150105818Abstract: A method of treating a constricted sinus passageway of a patient includes traversing the canine fossa region of the patient so as to form a passageway in the sinus cavity. A cannula is positioned in the passageway. A visualization tool such as an endoscope is passed through a lumen or channel in the cannula to aid in visualization of the anatomical site of interest. A balloon dilation catheter is then deployed through or along the cannula so as to place the balloon within or across the constricted anatomical space (e.g., ostium). The balloon is then expanded so as to expand at least a portion of the constricted anatomical space. Alternative embodiments include the use of an optional guide wire and incorporating a endoscope lumen through the balloon dilation catheter.Type: ApplicationFiled: December 17, 2014Publication date: April 16, 2015Inventors: Peter T.
