Patent number: 12004707Abstract: An airway visualization system is described herein having an elongate delivery sheath and defining at least one lumen therethrough, wherein the length is positionable within an airway of a subject. An isolation component positioned near or at a distal end of the elongate delivery sheath is expandable to at least partially obstruct the airway and a controller is in communication with the delivery sheath. The controller is also configured to manipulate a fluid flow through the at least one lumen whereby a pressure change within the airway of the subject is imparted sufficiently to at least partially expand or collapse the airway to alter the density of the airway.Type: GrantFiled: August 20, 2020Date of Patent: June 11, 2024Assignee: The Board of Trustees of The Leland Stanford Junior UniversityInventors: Bryan I. Hartley, Norbert Pelc, Dimitri Augustin, Racquel Redwood, Zach Wolf, Benjamin Berkowitz, Harmeet Bedi
