Magnetic Milli-Spinner for Robotic Endovascular Surgery.

ABSTRACT: Navigating the complex and high-flow environment of human vasculature remains a major challenge for conventional endovascular tools and externally actuated tethered systems. While catheter-based approaches are the clinical standard, their limited steerability and force transmission hinder access to tortuous or distal vessels, especially in the brain. Untethered robotic systems have emerged as a promising alternative for enhanced flexibility and reachability. However, most designs struggle against the high, pulsatile blood flow in human arteries. Here, the study presents a magnetically actuated milli-spinner robot that overcomes existing limitations in navigating complex and high-flow vasculature. Capable of swimming at 23 cm·s^-1 (73 body lengths per second), the milli-spinner en
