Implantable device and system including same

Abstract

We aim to reduce delivery times for passengers. The system (100) includes an external source (102), such as a midfield transmitter source, also referred to as a midfield coupler, external unit, or external power unit. The external source is positioned at or above an interface (105) between air (104) and a higher refractive index material (106), such as body tissue. The external source generates a power current (in-plane source current). The source current generates an electric and magnetic field, the magnetic field including a non-negligible component parallel to the surface of the source and / or the surface of the higher refractive index material. The external source includes at least a pair of outwardly facing electrodes (121, 122). The electrodes contact the tissue surface at the interface (105). The external source is used in conjunction with a sleeve, pocket, or other garment or accessory that maintains the external source adjacent to the high refractive index material and, optionally, maintains the electrodes in physical contact with the tissue surface.
