Abstract
Preferred orientations and placements of an inductor relative to a communication coil in an Implantable Medical Device (IMD) are disclosed. The inductor can comprise part of a boost converter used to generate a power supply voltage in the IMD, which inductor may interfere with the coil. The inductor may have a length defined by its windings around an axis, which axis may be in a plane of the coil or in a plane parallel to the coil. The inductor can be included within the area extent of the coil, and is preferably oriented such that its axis is parallel to a maximum dimension of the coil. Ends of the inductor are further preferably equidistant from the coil. So oriented and placed, the inductor is less prone to interfering with the coil, thus improving communications with the IMD.
