Abstract
An implantable medical device comprised of a lumen. When the device is, at different points in time, exposed to two different radio frequency electromagnetic radiations, one of whose frequencies differs from the other by a factor of at least 1.5, at least 90 percent of each of the radio frequency electromagnetic radiations penetrates to the lumen of the device.
