Patent number: 11517692Abstract: A ventilator conduit for a reversible airway device (RAD) is provided. The RAD can include a supra-glottic support member connected to a tubular guide (TG) having oppositely disposed proximal and distal end portions and TG lumen, which extends between the ends and is defined by an inner surface. The RAD can be physically free of an endotracheal tube. The ventilator conduit can include a hollow tube having first and second ends, and a ventilator conduit lumen extending between the ends. The first and second ends can be adapted for connection to a ventilator circuit and insertion into the TG lumen, respectively. At least the second end of the hollow tube can be sized and dimensioned so that, upon insertion into the TG, an outer surface of the second end is brought into direct contact with a portion of the inner surface to form an air-tight seal therebetween.Type: GrantFiled: September 30, 2016Date of Patent: December 6, 2022Assignee: THE CLEVELAND CLINIC FOUNDATIONInventor: Rafi Avitsian

Patent number: 10786640Abstract: One aspect of the present disclosure relates to a reversible airway device. The reversible airway device (10) can include: a supra-glottic airway support (12) comprising a multi-lumen tubular guide (14) and an optional sealing member (16); an endotracheal tube (26); and at least one seal (42). The multi-lumen tubular guide has a distal end portion (18), a proximal end portion (22), a first passageway (20) extending between the distal and proximal end portions, and a second passageway (24) that is non-concentric with the first passageway and also extends between the distal and proximal end portions. The at least one seal is disposed within the first passageway, the second passageway, or both, so as to occlude the flow of a gas through the first passageway and/or the second passageway. The endotracheal tube can be inserted into the first or second passageway and can traverse the seal.Type: GrantFiled: May 16, 2016Date of Patent: September 29, 2020Assignees: PARKER-HANNIFIN CORPORATION, THE CLEVELAND CLINIC FOUNDATIONInventors: Rafi Avitsian, Andrew Zura, Gino Banco, Sean Lee
