The magnetic field has unique advantages in manipulating miniature robots working inside
the human body, such as high transparency to biological tissue and good controllability for …

The endovascular intervention has been widely used to treat occlusive peripheral vascular
disease (PVD). However, the current procedure has concerns such as low successful rate …

This study presents a separable and recombinable magnetic robot (SRMR) to deliver and
retrieve an untethered magnetic robot (UMR) to a target vascular lesion safely and …

A multifunctional magnetic catheter robot (MCR) is proposed in this article to treat occlusive
vascular disease by generating steering, tunneling, and stent delivery motions. Using …

Magnetic microrobots are propelled by magnetic fields or magnetic field gradients generated
by electromagnetic systems. Generally, 3D Helmholtz coils systems are used for microrobot …

As a fundamental instrument in vascular interventional surgery, guidewires inherently face
limitations when navigating through complex curved blood vessel bifurcations due to their …

The size limitations and tortuosity of the neurovasculature currently exceed the capabilities
of existing robotic systems. Furthermore, safety considerations require a fail-safe design …

In this letter, we propose a physics-based framework to exploit magnets in robotic
manipulation. More specifically, we suggest equipping soft and underactuated hands with …

In this study, the authors developed a novel active guidewire including a spiral-type
magnetic microrobot and ball joint to realize active locomotion and improve the steering …

Tip positioning of a wire-driven catheter tube is a great challenge during surgeries and it is a
significant problem. In order to successfully position the tip to the desired location, a reliable …
