Abstract
A cardiac defibrillator includes a fibrillation detector, which determines when a medical patient requires defibrillation at which time a transmitter produces a radio frequency signal. A first stent electrode is implanted into a blood vessel at a first location in the medical patient and a second stent electrode is implanted into a blood vessel at a second location. The first stent electrode contains an electronic circuit that is electrically connected to the second stent electrode. In response to receiving the radio frequency signal, the electronic circuit uses energy from that signal to apply an electric defibrillation pulse between the first and second stent electrodes.
