Micro-motor developed to treat strokes

24 July 2012

An Australian research team has created a motor that is so small it can be driven through the arteries of the brain.

The motor is about the size of a grain of salt and is said to have the equivalent power of a small kitchen appliance.

It is invisible to the naked eye.

The current technology is a fixed tube that feeds a catheter to the site of a stroke, but when it is powered by the new motor doctors will be able to steer the catheter.

Associate Professor Bernard Yan of the Royal Melbourne Hospital’s neuro-intervention service is hoping to use the micro-motor to treat strokes and aneurisms.
