A Novel Endovascular Robotic System for Treatment of Lower Extremity Peripheral Arterial Disease: First-in-Human Experience

There were some reports about several robotic systems used in the peripheral arterial disease, but no robotic system was able to perform entire procedure of endovascular treatment of lower extremity peripheral arterial disease (PAD).To solve this problem, we designed a remote-control novel endovascular robotic system. It was the first robotic system that can perform entire procedure of endovascular treatment of PAD worldwide. A novelty retrieval report about this is provided in the supplementary materials.The robotic system is compatible with all commercial endovascular surgical devices currently available in the market, including guidewires, catheters and stent delivery systems. It can perform all types of motion, such as forward, backward, and rotation to meet the requirements of all types of endovascular procedures. During the operation, the robotic system can perform these operations in a fine-tuned manner, so it is easy to cross the lesions, which is the key factor influencing the success rate of the operation. In addition, the robotic system can effectively reduce the exposure time to radiation, thereby reducing the risk of occupational injury.
