Abstract
An implantable medical device has an electronic circuit and a telemetry circuit both connected to a common ground, and at least one RF telemetry antenna that is formed by a number of parts of the implantable device that are capable of functioning as an antenna. When implanted, these parts are in contact with tissue. For voltage protection, the RF antenna circuit is connected to the parts of the RF telemetry antenna via at least one capacitor. The capacitor is dimensioned to withstand a voltage amplitude of a pulse that would be capable of modifying the state of, or destroying, any component in the RF telemetry circuit or the electronic circuit.
