Wireless cardiac pacing system with vascular electrode-stents

摘要

A cardiac pacing apparatus has a source of pacing pulses that are transmitted through the animal by a radio frequency signal. An electrode-stent is implanted in a blood vessel adjacent to the point at which stimulation is desired. The electrode-stent contains an electrical circuit that is tuned to the radio frequency signal and which responds to receipt of that signal by applying an electric current to tissue of the animal. <IMAGE>
