Abstract
An apparatus for testing the impedance of a medical lead connecting an implantable stimulation device to a nerve or a muscle. The implantable device is of the type comprising a capacitor for stimulating the nerve or the muscle. The system of the invention comprises a current generator for generating a testing current 'I' during a calibrated testing pulse and a power circuit coupled to the capacitor and to the current generator for determining if the capacitor is charged by the testing current during the calibrated testing pulse.
