A team of engineers from the Massachusetts Institute of Technology (MIT) in the United States has created a robot in the form of a thread that can move through the arteries of the brain, while controlling it through magnetic field techniques.
The researchers said it is possible to develop this robot in the future and provide it with therapeutic means that allow it to dissolve strokes and deal with small tumors inside the brain.
"Strokes are the fifth leading cause of human death and a major cause of paralysis in the United States. During the first 90 minutes of a stroke, the survival rate is very high. "
"If a device can be designed to remove the blockage inside the artery during this (golden hour), it is possible to avoid permanent brain damage."
The robot's body is made of nickel-titanium, a durable and flexible material that can flex and return to its original position without causing damage to the inner arteries.
The team wrapped the robot's body from the outside with a rubber paste containing magnetic particles. The researchers also surrounded the body of the robot from the outside of hydrogel, which does not affect its magnetic properties, but it provides a high degree of fluidity and ease of movement within the human body.
