Abstract
Navigating the intricate and narrow vascular pathways of the body remains a formidable challenge in vascular embolization, often limiting the maneuverability and steerability of traditional catheters. This study, by T.T. Xu and co-workers, introduces dual-responsive reconfigurable miniature fiberbots, which are capable of catheter-assisted deployment, navigation, and embolization in vascular systems. Through meticulous design and magnetic control, this work successfully validates a multistage vascular embolization approach in the renal artery of rabbits invivo. The experiments not only overcome the existing limitations of conventional catheterization techniques but also open new avenues for minimally invasive treatments.
