ICP Monitor

ICP monitoring is an important parameter in the diagnosis, management, and follow-up of patients with neurological conditions such as traumatic brain injury (TBI) stroke and brain surgeries.
The market potential for ICP monitoring is much larger than the current market size. From the current 4.5 million annual potential procedures in the U.S.
only around 200,000 invasive ICP monitoring procedures are performed. The small number of procedures derives from the invasive nature of the current gold- standard, and due to the fact that some patients are unable to undergo the procedure.
The current non-invasive methods for ICP monitoring that are available today are not accurate enough for routine use and most of them did not reach commercial stage, which leads to a real need for a non-invasive accurate and continuous method to monitor ICP.

The Headsense device

HeadSense HS-1000 non-invasive ICP monitor is a single-use disposable capable of performing accurate and continuous monitoring of ICP in mmHg.
The device contains a disposable front-end unit and a tablet based monitor.

The front-end is an ear-buds like device that is placed on the patient’s ears like any standard ear-buds. a Low frequency acoustic signal is generated by the front-end for a few seconds short duration.
The signal propagates through the cranium and is picked up in the other ear by an acoustic sensor.
The received acoustic data is then analyzed using proprietary signal processing algorithms, and in a matter of few seconds the patient’s ICP level in mmHg is available.
The procedure can be repeated automatically for continuous monitoring.


The system is comprised from the following parts:

  • HS-1000F front-end: Disposable ear-buds like device that sends an acoustic signal in one ear, picks it up in the other ear, and sends it to the monitor.
  • Hs-1000M Monitor: An Android based tablet that includes the software and algorithms that calculates the ICP value in mmHg and displays it to the user.
