    摘要： Devices and methods are provided for trans-esophageal aortic flow control. The device comprises a controller, an esophageal tube extending from the controller, an anchor device at a distal end of the esophageal tube and configured to anchor the distal end of the device inside a patient's stomach, and an actuator positioned proximally to the anchoring device by a sufficient distance so that the actuator will be proximal to the intersection of the patient's esophagus with their diaphragm when the anchoring device is positioned inside of the patient's stomach. In this position, the anchoring device is aligned with the location at which the patient's esophagus and aorta cross that is above (or proximal to) the intersection with the patient's diaphragm, with the patient's aorta then positioned between the spine and the esophagus. Thus, when the actuator is engaged, a compressive force is applied by the actuator against the interior of the patient's esophagus and, in turn, upon their underlying aorta so as to significantly occlude blood flow through their aorta and reduce the risk of lethal hemorrhaging from an abdominal wound.

    摘要： A device and method is provided herein for esophageal impingement of a patient's aorta. The device may be inserted into a patient's esophagus and positioned at the location where the esophagus passes over the patient's aorta. In this position, an actuation device is used to apply pressure to the patient's aorta through their esophagus to impinge or occlude the aorta to stop or significantly reduce hemorrhaging. A manually operable actuator handle enables a physician to manipulate a head assembly of the device through three distinct degrees of freedom of movement so as to control placement and direction of force against the patient's esophagus and, in turn, their aorta.
