Abstract: A communication device includes: a board having a first surface, a second surface opposite to the first surface, and a third surface different from both the first surface and the second surface; a first magnetic sheet disposed on a side of the first surface; a first coil disposed on the first magnetic sheet; a second magnetic sheet disposed on a side of the second surface; a second coil disposed on the second magnetic sheet; and a third coil disposed on the third surface. A part of the first magnetic sheet overlaps at least a part of the third coil in plan view.

Abstract: Embodiments of the present invention concern the timing of sending one or more commands to control circuitry of a multi-electrode lead (MEL). In one embodiment, the one or more commands are sent to control circuitry within the MEL during a predetermined portion of a cardiac pacing cycle to avoid potential problems of prior systems that were not synchronized with the cardiac pacing cycle. In one embodiment, the one or more commands are sent when cardiac tissue is refractory from a cardiac pacing pulse, to prevent the command(s) from potentially undesirably stimulating cardiac tissue. The command sending can occur such that the one or more commands are sent between instances when sensing circuitry of the implantable cardiac stimulation device is being used to obtain one or more signals indicative of cardiac electrical activity, to prevent interference between the one or more commands with the signals indicative of cardiac electrical activity that are sensed.
