Sometimes events do not occur as often, or are harder to catch. In this situation, your physician may suggest an ILR . This device is about the size of your pinkie. This procedure is done in an outpatient hospital setting and is implanted under the skin. The incision made is usually about one inch.
Anytime an event occurs, it is recorded and is read with radio waves by a programmer machine. This device can be worn for up to a year, as the battery life expectancy is about 14 months. The same procedure would be repeated for removal of the device. This device does not send out electricity, it is simply a recording device.
