Led by Brad Nelson, professor in the Multi-Scale Robotics Lab (MSRL) at ETH Zurich, the team hopes to tackle what they believe is the biggest challenge in removing blood clots blocking blood flow to the brain during stroke — the complex structure of the blood vessels.
In the technology developed by this team, the patient lies next to a navigation system that generates a directed magnetic field. The team’s microrobotic catheter features a diameter measuring at less than one millimeter and a soft magnetic tip. This magnetic catheter tip can be steered in all directions using control software. ETH Zurich’s team says th…
