Medtronic said the LINQ II Insertable Cardiac Monitor (ICM) system has received 510(k) clearance by the U.S. Food and Drug Administration (FDA) for use in pediatric patients over the age of 2 who have heart rhythm abnormalities and require long-term, continuous monitoring.
The LINQ II system is a small (one-third the size of a AAA battery), wireless ICM for patients with abnormal heart rhythms who experience infrequent symptoms including dizziness, palpitations, syncope (fainting) and chest pain, thereby requiring long-term monitoring or ongoing management. The LINQ II ICM, which has a battery life of up to 4.5 years, allows patients to undergo magnetic resonance imaging (MRI) when needed, and, as an implantable device, does not interfere with daily activities such as showering, bathing, or swimming. The latest-generation device has been implanted in thousands of patients globally since it was first commercialized in 2020.
The LINQ II ICM system also includes the recently launched AccuRhythm AI algorithms, which applies artificial intelligence (AI) to heart rhythm event data collected by the LINQ II ICM, improving the accuracy of information physicians receive so they can better diagnose and treat abnormal heart rhythms. The two AI algorithms have shown to reduce the number of false alerts specific to the most common ICM false alerts — atrial fibrillation (AF) and pause (asystole) — by 74.1% and 97.4% respectively, while preserving more than 99% of true alerts.
With integrated remote patient management, patients or their caregivers can choose to use their smartphones with the LINQ II ICM to automatically transfer device data via the MyCareLink Heart mobile app using BlueSync technology that enables secure communication via Bluetooth.
Medtronic has been a pioneer in the development of insertable cardiac monitors for more than 20 years; to date, more than 1.7 million patients have received a Medtronic ICM.
