A magnetically steerable catheter for quick and safe stroke treatment ETH_en
."Not only can the catheter tip be bent in any direction thanks to a magnetic head; it's also smaller, more maneuverable and safer due to the softness of the material," explains ETH alumnus Christophe Chautems, one of the three founders of Nanoflex.In future, the magnetic catheter's precision steering will speed up and simplify procedures compared to conventional catheters.
But it doesn't stop there."With our system, it will be possible to carry out procedures from a distance by remote control and on a screen," says Silvia Viviani, who studied robotics at ETH Zurich and has worked at Nanoflex since 2021. The researchers at the start-up are hoping that, in future, stroke patients will be operated on—as quickly as possible—at the nearest local hospital by a specialist who doesn't even have to be on the premises. This would save precious time.
and researching how to downsize the system."Our goal was to generate a magnetic field within the smallest possible space to bring the size and weight of the equipment down. We finally cracked it by developing a new, now-patented cooling system for the electromagnet," explains Chautems, who comes from the western part of Switzerland and first joined ETH Zurich for his Bachelor's degree in mechanical engineering.
