About

Junchi Sa is a rising researcher in the field of robotic endovascular intervention, with a focus on magnetic actuation and minimally invasive medical robotics. His work centers on the design and control of magnetic helical robots and navigation systems for treating occlusive vascular diseases, such as thrombus drilling and targeted drug delivery. Sa’s most-cited paper introduces a separable and recombinable magnetic robot (SRMR) that enables safe delivery and retrieval of untethered magnetic robots to vascular lesions—a key contribution toward precise, tetherless intervention. His other notable works include a sawtooth-head helical robot design that improves drilling performance over conventional cone-shaped heads, and a voltage minimization control method for magnetic navigation systems that enhances rotating magnetic field generation while reducing power demands. These innovations address critical challenges in actuation efficiency and procedural safety. With over 30 citations on his leading paper and growing recognition, Sa is establishing himself as a promising contributor to next-generation robotic endovascular therapies.
