摘要： 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.

摘要： A responsive material having an elastomeric matrix in which ferromagnetic particles are dispersed so as to have a predetermined magnetization pattern which, when exposed to an external magnetic field, changes the shape of the responsive material from an initial shape to a predetermined transformed shape dictated by the magnetization pattern. An initial shape of the responsive material is formed by direct ink printing while applying magnetic fields to a dispensing nozzle to align the particles and gives rise to the desired magnetization pattern.
