Method and Device for Wireless Energy Transmission From a Magnet Coil System to a Working Capsule

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.
