Sending small robots deep into the human brain to deal with brain problems has long been a science fiction — but soon it may become a reality, according to a California startup.
“The idea of micro-robots originated long before I was born,” said founder and CEO Michael Shpigelmacher.
“One of the most famous examples is Isaac Asimov’s book and the film ‘Fantastic Voyage,’ in which a group of scientists board a small stimulus vessel into the brain, to treat blood clots.”
Just as cell phones now contain powerful substances that are less than grains of rice, the technology behind it micro-robots “which was a science fiction in the 1950s and 60s” is now “the reality of science,” says Shpigelmacher.
“We want to take this old idea and turn it into reality,” the 53-year-old scientist told AFP during a tour of his Los Angeles research and development center.
Working with leading German research firm Max Planck, Bionaut Labs decided to use magnetic field energy to move robots — rather than optical technology or ultrasonic technology — because it does not hurt human body.
Magnetic rods placed outside the patient’s skull are connected to a computer that can control the micro-robot from a distance into the affected part of the brain, before removing it in one way or another.
All devices can be operated easily, unlike MRI, and use a power output of 10 to 100 times.
In a cement watched by the AFP news agency, the tiny millimeter-long, cylindrical metal cylinder — slowly following a pre-arranged path through a gel-filled box, imitates the size the human brain.
As soon as he approached the bag full of blue water, the robot quickly moved like a rocket piercing the bag with its pointed end, letting the water out.
Innovators hope to use statue to puncture fluid-filled cysts in the brain when clinical trials begin within two years.
If successful, the system could be used to treat Dandy-Walker syndrome, a brain disorder that rarely affects children.
Victims of birth defects may have large golf cysts, which swell and increase pressure on the brain, resulting in a potentially dangerous condition.
Bionaut Labs has already tested its robots large animals like sheep and pigs, and “information shows that technology is not safe for us” humans, says Shpigelmacher.
If they are approved, the statue may offer significant benefits over the treatment available mental illness.
“Today, more brain surgery and brain interference is limited to the right line – if you do not have the right line to the target, you are stuck, you will not get there, ”said Shpigelmacher.
Small-scale technology “allows you to reach goals that you could not reach, and achieve them on a regular basis in the best possible way,” he said.
The U.S. Food and Drug Administration (FDA) last year approved Bionaut Labs which allows clinical trials to treat Dandy-Walker syndrome, as well as malignant gliomas — brain cancer is usually considered ineffective.
In the latter case, micro-robots will be used to inject cancer drugs directly into a brain tumor in a “surgical strike.”
Therapeutic approaches include throwing bombs all over the body with drugs, causing serious side effects and loss of effectiveness, Shpigelmacher said.
Micro-robots can also weigh and collect tissue samples while in the brain.
Bionaut Labs – which has about 30 employees – conducted discussions with partners to use its technology to treat certain brain-related conditions including Parkinson’s, epilepsy or stroke.
“To the best of my knowledge, we are the first business venture” to design such a product with a “definitive approach to clinical testing,” Shpigelmacher said.
“But I don’t think we are the only one … This area is getting hotter.”
