摘要：
An implantable medical device (IMD) can include an implantable pulse generator (IPG), such as a cardiac pacemaker or an implantable cardioverter-defibrillator (ICD). At least one lead is coupled to the IMD at a proximal end to the anatomic tissue of a patient at a distal end. According to various embodiments, a one-quarter wavelength open circuit terminated transmission line forms a stub filter to attenuate an interfering signal, such as those created by an MRI scanner during an MRI procedure. By cancelling the interfering signal, both the IMD and patient are protected from any adverse effects caused by the interfering signal.
