Microscopic medical robots capable of translating in a
bloodstream or similar liquid represents a new type of
therapeutic technology for endo-vascular interventions.
Local drug delivery of diagnostic and chemotherapeutic
agents could be delivered to tumors, blood clots, and
infections. Microcapsule control in such a situation
presents a barrier for the implementation of this
technology. Magnetohydrodynamic (MHD) voltages are
created in major vasculature when blood ejected into the
aortic arch during early systole interacts with the
strong magnetic field of the MRI. By utilizing the MHD
effect within the strong magnetic field of the MRI (Fig.
1), the opportunity to propel a device and provide
imaging is presented simultaneously. We hypothesized
that a wireless MHD-driven thruster could be developed
for the application of controlling microscopic endo-capsules
within the strong magnetic field of the MRI scanner.
