The U.S. Air Force’s 60th Medical Group at Travis Air Force Base has developed improved devices for hemostatic management of patients with life-threatening blood loss from an arterial wound or surgery. The lifesaving devices are available via patent license to companies who would make, use, or sell them commercially.
Current aortic occlusion devices successfully stem aortic blood loss but result in hypoxia below the occlusion device. These devices, by blocking blood flow and oxygen delivery, severely limit the amount of time that such resuscitative measures can be taken before other medical complications arise. The major improvement in the present endovascular variable aortic control (EVAC) device is that it occludes blood flow, but not entirely, with some control. Specifically, EVAC allows greater control in the level of aortic blood flow and pressure on either side of the occlusion barrier.
EVAC features either non-balloon or balloon-based occlusion capabilities in a multi-lumen catheter, which includes an external regulation device that allows medical staff to regulate blood flow and pressure by affecting the aperture of the window in the main channel of the device.
- Increases the amount of time a patient with severe blood loss has to reach definitive vascular repair
- Allows up to 15% blood flow within the occluded vessel while maintaining internal blood pressure
- External regulation of blood flow and pressure possible through a device affecting aperture of internal lumen
- Diverse potential applications including arteries and other vessels away from the heart
- Businesses can commercialize the invention by licensing U.S. Patent 10,279,094 and International Patent Application WO201611859, along with additional unpublished patent applications from the Air Force
- License fees paid to the Air Force are negotiable
- TechLink guides businesses through evaluation and Air Force licensing process, services provide at no charge
