• Guide-wired Helical Microrobot for Percutaneous Revascularization in Chronic Total Occlusion in-vivo Validation

    3 monthes ago - By EMBS

    Here we show an enhanced powered guide wired helical millirobot for mechanical thrombectomy in cardiovascular intervention capable of autonomous therapeutics. We build up and demonstrate a millimeter robot fabrication with a spherical joint and a guidewire, a high-power and frequency actuation via external electromagnetic field control, and autonomous therapeutic motions comprise driving, steering, and drilling. We validate all performances in two-dimensional fluidic channels mimicking the vascular network and finally in-vivo environments. Beyond nature-inspired millirobot technologies...
