MAGNETICALLY MANEUVERABLE IN-VIVO DEVICE

摘要

An in-vivo device includes a magnetic steering unit (MSU) to maneuver it by an external electromagnetic field. The MSU may include a permanent magnets assembly to produce a magnetic force for navigating the device. The MSU may include a magnets carrying assembly (MCA) to accommodate the permanent magnet(s). The MCA may be designed to generate eddy currents, in response to AC magnetic field, to apply a repelling force. The in-vivo device may also include a multilayered imaging and sensing printed circuit board (MISP) to capture and transmit images. The MISP may include a sensing coil assembly (SCA) to sense electromagnetic fields to determine a location/orientation/angular position of the in-vivo device. Data representing location/orientation/angular position of the device may be used by a maneuvering system to generate a steering magnetic field to steer the in-vivo device from one location or state to another location or state.
