    摘要: An endoscopy capsule contains an induction coil that is elongated along a longitudinal axis thereof, the endoscopy coil supplying power to components within the endoscopy capsule. A magnetic element in the endoscopy capsule has a magnetic dipole moment and interacts with an external magnetic field to navigate the endoscopy capsule within the body of a subject. The magnetic element is oriented so that the magnetic dipole element is aligned perpendicularly to the longitudinal axis of the induction coil. The endoscopy capsule has a cross-sectional area, in a plane having a normal aligned in the direction of the longitudinal axis of the induction coil, which contains both a cross-section through the magnetic element and a cross-section through the induction coil. The magnetic element has a length along the longitudinal axis of the induction coil so that the magnetic element projects beyond the induction coil at each end thereof.

    摘要: A coil arrangement for contact-free guidance of a magnetic element such as an endoscopy capsule, has a number of individual coils arranged in pairs by which the components of a guidance field are generated. By arranging the individual coils to include coils corresponding to blades at an exterior of a cylindrical surface, the number of degrees of freedom required for guidance can be obtained with fewer individual coils and fewer power amplifiers to operate the coils.

    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: In a method and device for wireless energy transmission between a magnetic coil system, having multiple excitation coils located outside of a patient, to a working capsule located in the patient, the working capsule has at least one induction coil, and a positioning device determines the position and orientation of the working capsule relative to the magnetic coil system. Using the position and orientation information, the magnetic coil system generates a first magnetic field that exerts a force on the working capsule at a location of the working capsule in the patient. The magnetic system also uses at least one of the position or the orientation to generate a second magnetic field for energy transmission to the working capsule at the location within the patient.
