This technology provides a medical micro-robot system to treat cerebral, coronary, and peripheral occlusive vascular diseases to prevent embolism. This medical micro-robot system consists of robot-assisted and adjustable magnetic navigation system, magnetic wireless micro-robot, and magnetic catheter. As this technology performs a procedure through the generation of a magnetic force and magnetic torque on a magnetic wireless micro-robot delivered to the lesion via a secondary magnetic catheter, it can simplify the procedural process and improve accuracy and success rate of the procedure.
This technology is applicable to surgical devices for interventional procedures such as catheters and endoscopes. This technology could be useful for medical doctors having difficulty in inserting or controlling catheters or guidewires through complex blood vessels. The technology provider is seeking for partners to work together from clinical trials to commercialization of this medical micro-robot system
TECHNOLOGY FEATURES & SPECIFICATIONS
The conventional devices such as catheters and guidewires are difficult to steer. So, medical doctors must repeatedly insert catheters and guidewires of various shapes to manually guide these devices to reach a lesion. As a result, treatment times can be lengthy and success rates can decrease causing side effects and long recovery times for the patient.
This technology provides dynamic magnetic fields which can generate motions of micro-robots and catheters by controlling the magnets inside these devices, and it can adjust the magnetic operating area according to patient’s lesion. This technology allows the medical doctors to easily perform intervention procedures through complex lesions.
Comparing with existing device, this technology can generate a rotating magnetic field which allows the magnetic wireless micro-robot that has a spiral structure to navigate and drill through a thrombus.

Guidewire – the global market size for guidewire, in which this technology is applicable, is approximately USD 887.6 million in 2018, and is expected to expand to about USD 1,401 million in 2026. The global catheter market is expected to grow at an average annual rate of about 5.9% by 2026.
Medical robot – the global market size for medical robot, in which this technology is applicable, is approximately USD 7.15 billion in 2019, and is expected to expand to about USD 20.7 billion in 2027. The global medical robot market is expected to grow at an average annual rate of about 14.2% by 2027.
Endoscope – the global market size for endoscope, in which this technology is applicable, is approximately USD 30 billion in 2018, and is expected to expand to about USD 45.4 billion in 2026. The global medical robot market is expected to grow at an average annual rate of about 5.4% by 2026.
By generating a magnetic force and magnetic torque on the magnetic wireless micro-robot, it can simplify the procedure process and improve accuracy and success rate of the procedure.
Since all medical processes can be performed remotely and in a non-contact manner through the medical micro-robot system, the medical staff can be protected from radiation exposure.
New treatment areas and methods such as occlusive vascular disease treatment of cerebral blood vessels that were even difficult to access with current technology can be developed.
