Stroke is the third-leading cause of death in the U.S. and the leading cause of disability.
While some 1.5 million people in the US
report stroke-like symptoms annually, half of them have actually not
suffered a stroke.
Making a reliable assessment of stroke in just
minutes would provide timely information for treating the victims faster, at lower cost, and with less risk. Jan Medical developed the first and so far the only portable brain sensing
device for rapid detection of ischemic stroke.
The device is aimed to
be used in the ER or ambulance, before a thorough evaluation can be made
in a hospital setting with a CT or MRI.
The device operation is based on an interesting principle of detecting the ultrasonic waves emitted by the skull. The device does not measure back-reflection of the emitted ultrasound from the brain;
instead, it measures natural mechanical vibrations of the skull.
vibrations are generated by a pressure wave of blood rushing from the
heart toward the skull during each pulse. In 5 minutes, the device
collects enough information to detect a variety of cerebrovascular
anomalies: an intracerebral or subarachnoid hemorrhage, epidural or
subdural hematoma, intracranial aneurysm, arteriovenous malformations,
ischemic stroke, or transient ischemic attack.
The device consists of
two primary components: a headset with sensors
and a controller for decoding the collected ultrasonic information
connected to a computer.
Jan Medical markets its device primarily for
early detection of stroke as well as the traumatic brain injury,
such as sports-related concussion that is often not detected on the
field leaving it to a discretion of a team physician to clear the player
for return to the game.
The device can also be used for rapid military
diagnostics of traumatic brain injury at the battlefield.
