Gastroesophageal Resuscitative Occlusion of the Aorta (GROA)

GROA is a minimally invasive device that can be used to rapidly stabilize a patient by controlling severe non-compressible abdominal hemorrhage at the point of impact. The GROA device non-invasively occludes the aorta by going into the mouth, down the esophagus, and into the stomach, stopping hemorrhage while maintaining blood flow to the heart and brain. It is also easily implemented in austere environments, such as battlefields or limited resource settings.

Intra-Peritoneal Hemostasis Device (IPHD)

A novel intraperitoneal balloon hemostasis device (IPHD) for rapid management of non-compressible torso hemorrhage (NCTH) in a variety of environments.

This rapidly deployable device will be percutaneously inserted into the abdomen and inflated to stop bleeding at the scene of the injury while en-route to a higher echelon of care.

Microvascular Tissue Oximetry

Microvascular Tissue Oximetry utilizes Resonance Raman Spectroscopy (RSS) to non-invasively measure tissue oxygenation from the inside of the patient’s cheek. The sensor can be placed in the mouth and provide oxygenation information in seconds, allowing for continuous monitoring or intermittent screening.
