Patent number: 10226590Abstract: A pressure support device implements compensation for variations in air density of its operating environment. A pressurized flow of breathable gas is generated for delivery to the airway of a subject. One or more parameters associated with the ambient environment of the pressure support device are determined. These parameters can include one or more of an ambient barometric air pressure, an ambient air temperature, or ambient air humidity. In some embodiments, one or more assumed parameters associated with the ambient environment of the pressure support device are determined based on typical sleeping conditions of the subject. An ambient air density of the ambient environment of the pressure support device is estimated based on one or more of the parameters and/or assumed parameters. A flow rate of the pressurized flow of breathable gas is adjusted based on the estimated ambient air density of the ambient environment of the pressure support device.Type: GrantFiled: February 25, 2013Date of Patent: March 12, 2019Assignee: Koninklijke Philips N.V.Inventor: Steven Adam Kimmel

Patent number: 10220170Abstract: Systems and methods for compensating long term sensitivity drift of catalytic type electrochemical gas sensors used in systems for delivering therapeutic nitric oxide (NO) gas to a patient by compensating for drift that may be specific to the sensors. In at least some instances, the long term sensitivity drift of catalytic type electrochemical gas sensors can be addressed using calibration schedules, which can factor in the absolute change in set dose of NO being delivered to the patient that can drive one or more baseline calibrations. The calibration schedules can reduce the amount of times the sensor goes offline. Systems and methods may factor in actions occurring at the delivery system and/or aspects of the surrounding environment, prior to performing a baseline calibration, and may postpone the calibration and/or rejected using the sensor's output for the calibration.Type: GrantFiled: October 4, 2016Date of Patent: March 5, 2019Assignee: Mallinckrodt Hospital Products IP LimitedInventors: Craig R. Tolmie, Jeff Milsap, Jaron M. Acker

Patent number: 10207062Abstract: A system and a method for generating a respirable dry powder aerosol (15) from a liquid solution or liquid suspension at a respirable dry powder aerosol volume flow (91). A liquid aerosol generating nozzle (3) generates from the liquid solution or liquid suspension a liquid aerosol (13) that is diluted by dilution gas (4) and dried in a cylindrical evaporation chamber (6) to generate a dry powder aerosol (14) that is subsequently concentrated by a cylindrical single linear slit aerosol concentrator (9). The system and method may include heliox as a gas, specifically dilution gas (4), for enhancing both the drying process in the cylindrical evaporation chamber (6) and for enhancing the concentration efficiency, but also as a nozzle gas (2) for enhancing generating the liquid aerosol (13) from the liquid solution or liquid suspension.Type: GrantFiled: October 11, 2016Date of Patent: February 19, 2019Assignee: KAER BIOTHERAPEUTICS CORPORATIONInventors: Donovan B Yeates, Xin Heng

Patent number: 10207069Abstract: Systems and methods for compensating for leaks in a ventilation system based on data obtained during periods within a breath in which the patient is neither inhaling nor exhaling. The methods and systems described herein more accurately and quickly identify changes in leakage. This information is then to estimate leakage later in the same breath or in subsequent breaths to calculate a more accurate estimate of instantaneous leakage based on current conditions. The estimated leakage is then used to compensate for the leak flow rates, reduce the patient's work of breathing and increase the patient's comfort (patient-ventilator breath phase transition synchrony).Type: GrantFiled: March 30, 2009Date of Patent: February 19, 2019Assignee: Covidien LPInventors: Mehdi M.

Patent number: 10206707Abstract: An epidural space is cleared of fat and scar tissue in preparation for implantation of a medical lead by utilizing a clearing tool. The clearing tool has multiple links that allow the creation of a deflection angle. A wire passes through the links and once the links are positioned with the desired deflection angle, tension is placed on the wire to lock the links into the current position. The clearing tool is inserted through a window into the epidural space, and once the tension is applied to the wire, the clearing tool becomes rigid to allow advancement of the clearing tool within the epidural space. The clearing tool is then removed from the epidural space, and the medical lead is inserted through the window and cleared epidural space until reaching the target site.Type: GrantFiled: October 16, 2015Date of Patent: February 19, 2019Assignee: MEDTRONIC, INC.Inventor: Sean P.
