Abstract
Robotic devices and methods for performing minimally invasive procedures on the vascular system, particularly cerebrovascular and endovascular neurosurgical procedures, where a submillimeter-scale continuum robotic device is configured and adapted for active steering and navigation based on external magnetic actuation. The submillimeter-scale continuum robotic device includes an elongate body having an inner core and an outer shell, where the outer shell is fabricated of an elastomeric material having a plurality of ferromagnetic particles dispersed therein.
