Patent number: 9675770Abstract: A method for regulating gas flows into and out of a patient includes repetitively forcing respiratory gases out of the lungs. Respiratory gases are prevented from entering back into the lungs during a time between when respiratory gases are forced out of the lungs. Periodically, an oxygen-containing gas is supplied to the lungs.Type: GrantFiled: March 2, 2015Date of Patent: June 13, 2017Assignee: ADVANCED CIRCULATORY SYSTEMS, INC.Inventors: Keith G.

Patent number: 9352111Abstract: A system includes a guidance device that provides feedback to a user to compress a patient's chest at a rate of between about 90 and 110 compressions per minute and at a depth of between about 4.5 centimeters to about 6 centimeters. The system includes a pressure regulation system having a pressure-responsive valve that is configured to be coupled to a patient's airway. The pressure-responsive valve is configured to remain closed during successive chest compressions in order to permit removal at least about 200 ml from the lungs in order to lower intracranial pressure to improve survival with favorable neurological function. The pressure-responsive valve is configured to remain closed until the negative pressure within the patient's airway reaches about ?7 cm H2O, at which time the pressure-responsive valve is configured to open to provide respiratory gases to flow to the lungs through the pressure-responsive valve.Type: GrantFiled: October 23, 2014Date of Patent: May 31, 2016Assignee: ADVANCED CIRCULATORY SYSTEMS, INC.Inventors: Keith G. Lurie, Anja Metzger

Patent number: 8210176Abstract: Systems and methods are provided for decreasing intracranial pressure and enhancing circulation in a breathing person, as well as for increasing the respiratory rate and encouraging spontaneous respiration. According to such methods, a valve system is interfaced to a person's airway. The valve system has a threshold valve and an airway member that interfaces with the person's airway. The threshold valve is configured to prevent respiratory gas flow to the person's lungs during a portion of an inhalation event until the inspiration equals or exceeds an opening pressure of the threshold valve. Also, a small level of external vacuum is constantly supplied at a juncture between the threshold valve and the airway member.Type: GrantFiled: June 18, 2008Date of Patent: July 3, 2012Assignee: Advanced Circulatory Systems, Inc.Inventors: Anja Metzger, Keith G.

Patent number: 8011367Abstract: A method for increasing circulation and providing oxygen to a patient in cardiac arrest includes the step of coupling an interface to the patient's airway, the interface providing access to the patient's respiratory system. A valve system is operably attached to the interface. Oxygen is delivered through the interface a rate of between about 1.0 to about 10.0 L/min to provide a continuous supply of oxygen to the patient. While supplying the oxygen, a body structure of the patient is manipulated to increase the magnitude and duration of the patient's negative intrathoracic pressure.Type: GrantFiled: February 27, 2007Date of Patent: September 6, 2011Assignee: Advanced Circulatory Systems, Inc.Inventors: Keith Lurie, Greg Voss

Patent number: 7836881Abstract: In one embodiment, the invention provides a device for decreasing intracranial or intraocular pressures. The device comprises a housing having an inlet opening and an outlet opening that is adapted to be interfaced with a person's airway. The device further includes a valve system that is operable to regulate respiratory gas flows through the housing and into the person's lungs during spontaneous or artificial inspiration. The valve system assists in lowering intrathoracic pressures during each inspiration to repetitively lower pressures in the venous blood vessels that transport blood out of the head to thereby reduce intracranial or intraocular pressures.Type: GrantFiled: March 8, 2004Date of Patent: November 23, 2010Assignee: Advanced Circulatory Systems, Inc.Inventors: Keith G.

Publication number: 20100179442Abstract: One method for diagnosing a cardiovascular-related condition in a breathing person comprises interfacing a valve system to the person's airway. The valve system is configured to decrease or prevent respiratory gas flow to the person's lungs during at least a portion of an inhalation event. The person is permitted to inhale and exhale through the valve system. During inhalation, the valve system functions to produce a vacuum within the thorax to increase blood flow back to the right heart of the person, thereby increasing blood circulation and blood pressure. Further, at least one physiological parameter is measured both prior to and while the person inhales and exhales through the valve system. The measured parameters are evaluated to confirm the initial diagnosis of a cardiovascular condition.Type: ApplicationFiled: March 12, 2010Publication date: July 15, 2010Applicants: Advanced Circulatory Systems, Inc., CPRx, LLCInventor: Keith Lurie
