摘要
An MRI-compatible electronic medical therapy system includes an active medical device connected to a plurality of electrodes. An independently actuatable switch selectively electrically connects at least one circuit protection device in electrical series with the electrodes and the medical device. The circuit protection device is adapted to permit current flow therethrough during normal medical device related therapy, but substantially prevent current flow therethrough in the presence of an induced electromagnetic field.
