Publication number: 20170368319Abstract: An inflation device includes a syringe body containing a bore. The bore holds a fluid that is used to inflate a separate device such as a dilation balloon. A plunger assembly slides within the syringe bore and contains a sealing member that forms a fluid tight seal with the syringe body. A shut-off valve is disposed within the distal end of the syringe body. The distal end of the syringe body has a fluid bypass channel fluidically coupled to the aperture of a connector. The shut-off valve has a spring-biased moveable piston with a bypass lumen contained therein, wherein the bypass lumen forms a fluid path between the bore and the fluid bypass channel when the pressure of the fluid is below a threshold value. The fluid path between the bore and the fluid bypass channel is interrupted when the pressure of the fluid is above the threshold value.Type: ApplicationFiled: July 6, 2017Publication date: December 28, 2017Applicant: ENTELLUS MEDICAL, INC.Inventors: Paul R.

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.
