Patent ID: 8359098

Claim:
An implantable medical device that is implantable in a biological tissue comprising: an energy storage device with an internal component and an outer case that encloses the internal component, the outer case having an outer surface, the outer case being electrically connected to the internal component, the energy storage device including a first electrode that is electrically connected to the internal component; and a control assembly with a control component and a control case that encloses the control component, the control case being coupled to and electrically connected to the outer case, the control case having an outer surface, the control component electrically coupled to the first electrode and the outer case to be powered by the internal component of the energy storage device, the control component controlling transmission of an electrical signal between the implantable medical device and the biological tissue, wherein the control component is supported by a circuit board, the control assembly further including a spacer that abuts the inner surface of the control case, the spacer supporting the circuit board to maintain the circuit board and the control component substantially in a fixed position relative to the control case, and wherein the spacer includes a plurality of protections that abut the inner surface of the control case and wherein the spacer includes a recess that receives an end of the circuit board.
