Abstract
Endovascular variable aortic control catheters (EVACC) are provided that are adapted to augment upstream blood pressure and regulate downstream blood flow for patients in shock. The EVACC devices provide improved treatment for truncal wounds, which may be used for example on a battlefield, thereby increasing survivability of injured soldiers. The devices are a catheter-based system having a proximal hand piece for controlled deployment of the device through a delivery sheath. A collapsible, wire framework supports an expandable and collapsible occlusion barrier. The wire basket and occlusion barrier expand to fit within the lumen of the aorta. Various movable elements are used to adjust an adjustable passageway to regulate controlled anterograde blood flow.
