Patent number: 10835723Abstract: 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: June 18, 2018Date of Patent: November 17, 2020Assignee: Entellus Medical, Inc.Inventors: Anthony J.

Patent number: 9694167Abstract: 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: GrantFiled: December 17, 2014Date of Patent: July 4, 2017Assignee: ENTELLUS MEDICAL INC.Inventors: Peter T.
