An implantable cardiac stimulation device and method provides reliable sensing of cardiac events to support cardiac pacing or fibrillation detection. In one embodiment, the guide can be moveable between an active position wherein the guide guides a saw blade and an inactive position wherein the guide does not guide the saw blade. According to the invention, a voltage potential difference generated across a respective pair of conductive members is used to control drug delivery via the respective port. The collectors of the transistors are connected via an impedance circuit to a bias voltage input terminal. The amine adduct is then oxidized to form an N-oxide that is pyrolized to form -p-mentha-2,8-diene-1-ol. The macroscopic mirror is made by a method comprising the steps of: preparing the silicon wafer by polishing one side to a predetermined flatness and etching the other side to a predetermined roughness; cutting the substrate section from the prepared silicon wafer to a predetermined shape and macroscopic size; and applying the plurality of layers on the flat, polished surface.
