Abstract: A device and method for occluding the descending aorta includes inserting a gastroesophageal resuscitative aortic occlusion device into a stomach of a patient through the esophagus. The gastroesophageal resuscitative aortic occlusion device includes a catheter having a body and a first lumen, and a distal end having a first opening fluidly coupled to the first lumen. An inflatable balloon is disposed on the catheter. An interior of the inflatable balloon is fluidly coupled to the first opening. An inflation device is operably connected to the catheter and fluidly coupled to the first lumen. Activation of the inflation device forces fluid into the interior of the inflatable balloon through the first lumen and the first opening. Activating the inflation device to pressurizes the inflatable balloon with a fluid. An external pressure device applies pressure to the abdomen of the patient until blood flow through the descending aorta is reduced or stopped.

Abstract: A blood flow restricting apparatus (100) is provided. The blood flow restricting apparatus (100) can include a frame element (70) configured to be securable to a user's head. At least one cooling pad (60) can be operatively arranged with the adjustable frame element (70) and configured to be arranged over a defined anatomic location including at least one of a pair of supratrochlear arteries (20), a pair of supraorbital arteries (30), a pair of temporal arteries (40), and a pair of occipital arteries (50) of the user's head. The at least one cooling pad (60) can include a cooling element (62) capable of producing a cooling effect. A pressurizing mechanism (90) can be operatively arranged with the at least one cooling pad (60) and capable of pressing the at least one cooling pad (60) against the defined anatomic location to restrict blood flow to each of the targeted arteries while simultaneously cooling the defined anatomic location.

Abstract: An inflatable tourniquet system for arterial blood occlusion of a leg or arm, e.g. after injury or for surgery. A tourniquet (TQ) is to be manually fastened around the limb by a user, e.g. a first aid helper, e.g. an untrained person. A manual inflator (B) is used to inflatable the tourniquet to appliy pressure for occlusion of arterial blood flow to the limb. An electric circuit (CC) measures an electrical input from a length sensor (C), e.g. an electric conductor, and to determine a value (R), e.g. electric resistance, indicative of circumference of the limb accordingly, when the tourniquet has been fastened around the limb. A blood pressure measuring circuit (BP) automatically determines a systolic blood pressure (SBP) in response to input from a pressure sensor (PS) arranged to measure a pressure (PR) of the tourniquet. A processor (P) is programmed to operate according to a control algorithm which calculates a target pressure (AOP, OAOP) in response to the measured SBP, and the value (R) indicative of circumference of the limb. Then, the processor monitors input from the pressure sensor (PS) and compares the sensed pressure with the calculated target pressure (AOP, OAOP). Visual and/or audible feedback (FB) is give to the user, when the pressure (PR) of the tourniquet (TQ) is within an interval of the target pressure (AOP, OAOP). In some embodiments, the manual inflator (B) process may be used to provide energy harvesting for electric powering the system.
