Abstract: Described is a locomotive implant for usage within a predetermined magnetic field. In one embodiment magnetohydrodynamics is used to generate thrust with a plurality of electrodes. In another embodiment, asymmetric drag forces are used to generate thrust.

Abstract: The present inventions provide a locomotive implant for usage within a predetermined magnetic field that includes a capsule body; a wireless power receiver disposed within the capsule body; a plurality of switchable conductors having a predetermined pattern within the capsule body, each of the switchable conductors adapted to pass a current along a forward path to thereby create, in the presence of the predetermined magnetic field, a force and assist in moving the locomotive implant; and a controller adapted to receive directional control signals to control the switchable current wires or conductors. Methods of using the same are described.
