Trans-Ocular Bioimpedance: Seeing the Brain through the Eyes (TOBI)


TOBI uses non-invasive electrical bioimpedance and ultrasound in a novel manner that evaluates intracranial pressure and monitors cerebrovascular autoregulation (CAR), one of the most important neuroprotective processes of the brain.

Value Proposition

The ability to monitor and manage Intracranial Pressure (ICP) following Traumatic Brain Injury (TBI) is critical. Trans-Ocular Brain Impedance (TOBI) is a compact wearable device that uses electrical bioimpedance and ultrasound to not only evaluate ICP but to also monitor cerebrovascular autoregulation (CAR), one of the most important neuroprotective processes of the brain.

Competitive Advantage

This technology is non-invasive, does not require an experienced operator, and is compact in size, meaning it can be used by caregivers across all echelons of care. TOBI could provide valuable early information on CAR to help inform the diagnosis and treatment of TBI.

MARKET OPPORTUNITY
Each year in the United States, an estimated 1.7 million people sustain a traumatic brain injury and 795,000 suffer a stroke. In addition to monitoring these injuries, TOBI can be used by caregivers across early echelons of care to monitor other illnesses such as cardiac arrest, sepsis, and any illness where failure to maintain autoregulation can result in severe neurologic impairment.
