Electromagnetically Controllable Microrobotic Guidewire for Robotic Vascular Procedures: In Vitro and In Vivo

Robotic magnetic systems offer potential advantages in interventional procedures, such as precise and fast control of magnetically steerable interventional tools (e.g., guidewires and catheters) in tortuous vessels. Recently, a robotic magnetic interventional system named ‘Electromagnetically Controllable Microrobotic Interventional System (ECMIS)’ that enables remote manipulation and active steering of guidewires for the treatment of cardiovascular diseases was developed. The ECMIS consists of a microrobotic guidewire in which a soft magnetically steerable robot (MSR) is attached to the tip of a guidewire, a human-scale electromagnetic control system, a biplane X-ray imaging unit, and a master-slave system. The flexible magnetic MSR at the tip of the guidewire exploits magnetic torques for active guidewire steering upon magnetic actuation. The microrobotic guidewire can be advanced and retracted by the master-slave system in a teleoperated manner. The ECMIS may open new avenues in multiple areas of vascular interventions.
