METHOD AND SYSTEM FOR PROPELLING AND CONTROLLING DISPLACEMENT OF A MICROROBOT IN A BLOOD VESSEL

摘要

The present invention relates to a method and system for propelling and controlling displacement of a microrobot through a patient's blood vessel. T he microrobot is formed with a body containing field-of-force responsive materi al wherein, in response to a field of force, the material undergoes a force in the direction of a gradient of the field of force. The microrobot is positioned in a blood vessel for displacement through the blood vessel, and a field of force with a given gradient is generated and applied to the microrobot in view of propelling the microrobot through the blood vessel in the direction of the gradient of the field of force. A direction and amplitude of the gradient of the field of force is calculated to thereby control displacement of the microrobot through the patient's blood vessel.
