摘要： An electromagnetic actuating device. A coil unit generates magnetic field toward a medical device inserted into a human body. An actuator drives the coil unit to move back and forth, thereby adjusting the rate of a change in magnetic force or magnetic field applied to the medical device. The coil unit moves linearly back and forth depending on the body shape of a subject and the body part to be diagnosed, such that actuation force is efficiently supplied to the medical device.

摘要： A magnetically guided endoscopy capsule is separated from the surface of water with the aim of immersing the capsule completely in water, using the least possible magnetic force. A brief force curve (F_mag(t)) is thereby automatically generated on the capsule by a solenoid system, by one or more force pulses. Assuming that the capsule floats on the water surface at the start of the force curve, a force curve is applied generating an odd number of force pulses having a step profile. Each odd force pulse brings about at least a partial immersion of the endoscopy capsule in the liquid, and each even force pulse bring about at least a partial emersion of the endoscopy capsule out of the liquid.

摘要： The present invention relates to a magnetic manipulation and navigation system for moving a magnetic element through a body comprising at least six electromagnets (24) with soft-magnetic cores arranged in a predetermined position to said body. It allows for the operation of one or more of the electromagnets in the non-linear regime of the magnetization curve of the cores. The system comprises at least one magnetic field sensor (104) at one or more predetermined positions outside of the operating region. While during operation in the linear region no feedback is required to set the magnetic field strength, during operation in the non-linear region feedback from the magnetic field sensors is used for closed-loop control. The system allows for operation in two separate modes, an open-loop mode operation in the linear regime for fast control signals such as they are required for stabilization during displacement of the magnetic element and a closed-loop operation in the non-linear regime for higher field strengths such as they may be required to apply forces and moments on the magnetic element while it is in contact with a surface.
