Distal Perfusion Balloon for Traumatic Aortic Injury and Complex Aortic Repair

詳細技術說明

None

*Abstract

BackgroundHemorrhage after penetrating injury of the torso is a common preventable cause of death on the battlefield. Bleeding in the torso is not amenable to external compression. Repair of these injuries is possible only in facilities with proper imaging equipment and expertise. Because the extent of hemorrhage can dramatically impact patient outcome, the major issue becomes how to stabilize patients during transport from the front line of a battlefield, as well as civilian traumatic aortic injuries.Technology DescriptionA Distal Perfusion Device was developed to temporarily cover the site of injury but importantly to maintain continued blood flow distal to the injury. In doing so, this device would stop further hemorrhage, and also reduce the complications of paralysis and organ failure. Due to the absence of suitable imaging on the front line, a prototype radiofrequency sensor was designed based on microelectromechanical (MEMS) technology that may allow for portable positioning of the device, as well as to transmit important patient vital signs.Applications1. Military benefit-Reduce bleeding on the battlefield to stabilize a soldier for transport to medical facility2. Civilian benefit-Emergency first responders can stabilize a hemorrhaging patient for transport to medical facility-Facilitate repair of aneurysms by replacing complex left heart bypassAdvantages-Covers vessel injury to prevent blood loss-Maintains distal perfusion to organs, lower extremities, and spinal cord-Sensors to detect device positioning and hemodynamic monitoring-No comparable approach to address life threatening, hemorrhagic injuriesStage of Development-In vitro data, in vivo data, animal studies-Prototype availableIP StatusPCT Application filed (PCT/US2014/046224)
