Ventriculostomy Simulator

Mixed-Reality Simulator of Ventriculostomy

This robust, turnkey, mixed-reality simulator simulates part of an anatomically correct head and skull for practicing, learning, teaching and debriefing a ventriculostomy (aka external ventricular drain, EVD) procedure.

Designed for austere environments, this medical simulator does not require wireless or internet access or wet fluids and accepts 110/220V, 50/60Hz. It can be unpacked, set-up, and operational in 5-7 minutes by an unfamiliar person. The portable simulator ships inside a military-spec padded case with inbuilt wheels and telescoping pull-handle that meets airline checked luggage size limits (L+W+H=60”) and weighs less than 50 lbs.

We can provide access to the simulator or copies of the simulator. Contact us for details.
