Trans-esophageal Aortic Compression Balloon

Tech ID #: 1178.1 CONNECT WITH A MANAGER FOR LICENSING

Massive blood loss from severe abdominal or distal limb trauma is challenging to control and necessitates surgical intervention. Current therapies rely on blood replacement products which can be difficult to obtain and may lead to complications for the patient. The trans-esophageal aortic compression balloon works to control blood loss, reducing the need to replace lost blood.

Description of Technology

The trans-esophageal aortic compression balloon is a non-invasive device that can assist with the control of blood loss from massive abdomial and/or distal limb hemorrhage.

Designed to be inserted into the esophagus, the compression balloon is inflated at the abdominal hiatus thereby compressing the descending aorta. Compression at the abdominal hiatus controls blood flow to the abdomen and distal limbs while still allowing blood flow to the heart and brain.

Importantly, the balloon can be cycled (inflated and deflated) leading to reduced blood loss while preventing circulatory collapse.

Areas of Application
  • Medical: trauma surgery
  • Military: combat assault care
IP Status
  • Patent Pending
Competitive Advantages
  • Allows for the control of blood flow distal to the hiatus while preserving blood flow to thorax and brain
  • Cycling prevents circulatory collapse
  • The technology may serve as a platform for additional devices:
    • Esophageal thermometer
    • ECG
    • Gastric pH monitor
Stage Of Development

Two small scale studies in anesthetized pigs have been performed.

  • Carotid and femoral blood flow was reduced under static and cycling conditions
  • Reduced blood flow is due to caval and aortic compression
