MICROROBOT SYSTEM FOR INTRAVASCULAR THERAPY AND METHOD OF CONTROLLING THE SAME

WIPO Patent Application WO/2013/032113

A1

The present invention relates, in general, to a microrobot system for intravascular therapy and, more particularly, to a microrobot system for intravascular therapy, which removes thrombus, clots and occlusions that are clogging blood vessels using the fast rotary power of a spherical microrobot having protrusions, thus treating clogged blood vessels. The microrobot system for intravascular therapy according to the present invention includes a spherical microrobot unit (100') including a magnet having an arbitrary magnetization direction and having protrusions formed on a surface thereof. An electromagnetic field generation unit (200) sets an alignment direction and a locomotion direction of the microrobot unit to arbitrary directions in the 3D space, generates magnetic fields, and then drives the microrobot unit so that the microrobot unit is rotated by itself or is propelled in the locomotion direction. An imaging unit (300) captures an X-ray image and then tracking a location of the microrobot unit.
