Publication number: 20190217067Abstract: 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: January 14, 2019Publication date: July 18, 2019Applicant: ENTELLUS MEDICAL, INC.Inventors: Paul R.

Publication number: 20190117259Abstract: A nasal valve implant delivery system includes a delivery tool having a handle and a needle extending distally therefrom and configured to hold an implant therein. When loaded in the needle, the implant proximally abuts or is disposed adjacent to a pusher member disposed partially within the needle. A light source disposed within the delivery tool is coupled to an optical fiber carried within a lumen of the pusher member. The delivery tool includes a moveable needle shuttle disposed in the handle that is coupled to the needle. An actuator disposed in the handle is configured to releaseably engage with the moveable needle shuttle, wherein the needle shuttle is coupled to one or more springs configured to apply a proximal tensioning force on the needle shuttle, wherein actuation of the actuator retracts the needle proximally into the handle and releases the implant.Type: ApplicationFiled: April 28, 2017Publication date: April 25, 2019Applicant: ENTELLUS MEDICAL, INC.Inventors: Andrew T.
