Stroke occurs when blood supply to part of the brain is being cut off and over 80 percent occurs due to blockage.
Thread-like robot device that delivers drugs inside the brain during the critical hour after the stroke has been developed by scientists. The device carries a laser which could be used to clear clogged vessels in the brain. It is half a millimetre thick and several centimetres long device.
How it Works
The core of the thread is a nickel-titanium alloy. The tip is covered with magnetic particles.
Outer hydrogel coating dramatically reduces friction.
Thread bends when a magnetic field is applied, allowing it to be steered throughout the blood vessel.
Through these means, it glides through the brain’s blood vessels to tackle blockage that causes stroke.
Stroke-related death in a year in various part of the world is about 35, 000. The device would definitely reduce the death rate due to stroke-related cases.
