Development of a Magnetohydrodynamically Driven Actuator for Use in MRI

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.
