The transmitter coil and the implantable coil individually comprises a number of turns. The number of turns in the transmitter coil and the receiver coil may be same or different.
In an embodiment, the loop structure is defined by a geometrical shape that includes a closed curve, defining a closed loop structure, wherein a point moving along the closed curve forms a path from a starting point to a final point that coincides with the starting point when the closed curve is in a closed mode. In one embodiment, the closed curve may include a single part loop structure comprising an openable section that includes a primary end and a secondary end. The openable section is attached to rest section of the loop structure at the primary end and is adapted to open the openable section at the secondary end (i.e. an open mode is defined when the openable section is open) to allow access to the hollow section and positioning of the part of the body part within the hollow section. The closed mode is defined when the openable section is engaged with rest of the section at the secondary end to form the closed curve. Alternatively, the closed curve may include multi-parts loop structure wherein the multi-parts includes a plurality of detachable parts, such as a first sub-part and a second sub-part, that are configured to attach with one another to form a closed loop structure. The closed mode is defined when the plurality of detachable parts is attached to one another. Accordingly, an open mode may be defined when the plurality of detachable parts is not attached to one another and in the open mode, the loop structure is adapted to allow positioning of the part of the body part within the hollow section of the loop structure. This may be achieved when the loop structure is in the open mode.
