Patent number: 10016163Abstract: The present invention is related to a device for acoustically monitoring a subject's airway to determine airway obstruction(s) and their location(s). The device is particularly useful when performing sleep analysis and sleep therapy, but is also highly useful in determining airway obstructions of any subject when the subject is sleeping or otherwise unconscious, and can further be used in certain applications when the subject is awake or conscious. The device, in its simplest form, is comprised of a supporting body (e.g. a mask, mouthpiece, or nasal cannula) used to position at least one acoustic generator and at least one acoustic sensor at a location essentially proximal to a subject's airway, the acoustic generator and acoustic sensor generating and/or sensing sound waves useful in determining obstruction(s) and their location(s) within the airway of a subject.Type: GrantFiled: March 18, 2013Date of Patent: July 10, 2018Assignee: Cleveland Medical Devices Inc.Inventors: Hani Kayyali, Brian Kolkowski

Patent number: 9995645Abstract: A ventilator is configured to assist a user with breathing, while eliminating the need for extraneous sensors and tubing normally found in prior art ventilators. The ventilator relies on a predetermined relationship between a measurable quantity associated with a compressed gas and the maximum pressure of that compressed gas upon delivery to the user. The measurable quantity may be mass flow rate of the compressed gas or pressure within a delivery lumen used to transport the compressed gas, among others. Based on the predetermined relationship, the control logic within the ventilator determines whether the pressure of compressed gas delivered to the user exceeds a maximum allowable pressure. When the maximum pressure is exceeded, the control logic initiates corrective action to reduce the pressure of the compressed gas.Type: GrantFiled: October 17, 2014Date of Patent: June 12, 2018Assignee: SILVERBOW DEVELOPMENT, LLCInventor: Todd Allum

Patent number: 9968750Abstract: A ventilatory assist system and method are disclosed. The system comprises a tube for connection to a patient's airway, inspiratory and expiratory tube lumens connected to the tube, an inspiratory air source connected to the inspiration tube lumen, and a controller of air pressure in the expiratory tube lumen. The pressure controller is responsive to a physiological breathing signal representative of patient's inspiratory effort to allow air flow through the expiratory tube lumen during a patient's expiration phase, partially restricting the air flow through the expiratory tube lumen to a so minimum air flow during a patient's inspiration phase. During both respiratory phases, a unidirectional air flow is produced through the inspiratory and expiratory tube lumens to prevent air expired by the patient from being breathed again. The physiological breathing signal allows synchronization of the ventilatory assist with breathing efforts of the patient.Type: GrantFiled: June 29, 2011Date of Patent: May 15, 2018Assignee: ST. MICHAEL'S HOSPITALInventors: Christer Sinderby, Jennifer Beck

Patent number: 9962473Abstract: The present invention provides a surgical aspiration cannula capable of aspirating a liquid component such as a small amount of blood while keeping an ability to aspirate a large clot such as a blood clot and to sweep them. The present invention relates to a surgical aspiration cannula that comprises a tip opening capable of aspirating a clot such as a blood clot; and an aspiration structure in the front of the tip opening. Due to the aspiration structure, the liquid component such as a small amount of blood can be aspirated. Further, even when the tip opening is pressed against the vicinity of an organ, the aspiration structure interposed between an aspiration port and a surface of the organ prevents clogging of the cannula or damage to the organ. In addition, in a case of bleeding in a surgical site, the blood is aspirated while controlling the bleeding by pressurizing a bleeding site, thereby providing a clear view and enabling a hemostatic site to be treated.Type: GrantFiled: June 4, 2010Date of Patent: May 8, 2018Inventor: Tohru Tani
