Patent number: 10716709Abstract: A method is disclosed for clearing effusion from an ear. The method may include applying liquid to an ear canal, which is proximal to a perforated tympanic membrane, which is proximal to a middle ear containing effusion, applying an ear device to seal and pressurize the liquid inside the ear canal, the ear device regulating the amount of pressure inside the ear canal, and inducing a Eustachian tube, which is distal to the middle ear, to open, which causes the fluid to displace the effusion into the Eustachian tube.Type: GrantFiled: May 23, 2017Date of Patent: July 21, 2020Assignee: Acclarent, Inc.Inventors: John H. Morriss, Greg Liu, Rohit Girotra, Tom Thanh Vo, Richard R. Newhauser, Jr., Thomas R. Jenkins, Joshua Makower
