The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the description focuses on automatic detection based on predefined arrhythmia classifications, not learning algorithms.
No
Explanation: The device is an insertable cardiac monitor designed to detect and record cardiac arrhythmias for diagnostic purposes, not to provide therapeutic treatment.
Yes
The device is an Insertable Cardiac Monitor (ICM) that records subcutaneous ECG to detect and classify cardiac arrhythmias, aiding in the diagnosis of conditions like atrial tachyarrhythmia/atrial fibrillation (AT/AF), bradyarrhythmia, pause, or (fast) ventricular tachyarrhythmia, especially in patients with symptoms suggesting a cardiac arrhythmia.
No
The device description explicitly states it is a "small, leadless implantable device" with "two electrodes on the body of the implantable device," indicating it includes hardware components beyond just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are performed outside of the body (in vitro).
- Device Function: The Reveal LINQ ICM is an insertable device that records subcutaneous ECG within the patient's body. It monitors electrical activity of the heart directly from under the skin.
- Lack of Sample Analysis: The device does not analyze samples taken from the body. It directly measures physiological signals.
Therefore, the Reveal LINQ ICM falls under the category of an implantable medical device for physiological monitoring, not an in vitro diagnostic device.

Device Description
The Reveal® LINQ™ Insertable Cardiac Monitor (ICM) Model LNQ11 is designed to record the occurrence of arrhythmias in a patient. Arrhythmia may be classified as atrial tachyarrhythmia/atrial fibrillation (AT/AF), bradyarrhythmia, pause, or (fast) ventricular tachyarrhythmia. The Reveal LINQ ICM provides storage of ECG and Marker Channel during patient-activated and automatically-detected (auto-activated) events. Auto-activation may help to detect abnormal heart rhythms in patients who may not activate/trigger the ICM. The Reveal LINQ Model LNQ11 is a small, leadless implantable device that is typically implanted under the skin, in the chest. Two electrodes on the body of the implantable device continuously monitor the patient's subcutaneous ECG.
Medtronic Reveal LINQ (Model LNQ11) ICM
The Reveal LINO ICM is a small, leadless implantable device that is implanted under the skin, in the chest. The implantable device uses two electrodes on its surface to monitor the patient's subcutaneous ECG continuously. The implantable device memory can store up to 27 min of ECG recordings from automatically detected arrhythmias and up to 30 min of ECG recordings from patient-activated episodes. The system provides 3 options for segmenting the patientactivated episode storage: up to four 7.5 min recordings, up to three 10 min recordings, or up to two 15 min recordings. Arrhythmia detection parameters are set to pending automatically, based on patient information entered on the programmer during pre-insertion implantable device setup: the patient's Date of Birth and the clinician's Reason for Monitoring the patient. Arrhythmia detection parameters can also be programmed manually by the clinician. The following table describes the Reveal LINO ICM Model LNO11 when used with the alternative LINO Programmer Application and patient connector as compared to the Reveal LINQ ICM Model LNQ11 when used with the existing programmer software and hardware.

The Reveal LINO ICM Model LNO11 was initially cleared via a 510(k) application K132649 on February 14, 2014. This submission introduces an alternative programming option (referred to as the LINQ Programmer system) for the Reveal LINQ ICM. The LINQ Programmer system is comprised of LINO Programmer Application Model MSW001 installed on a clinician's off-theshelf non-medical mobile device and patient connector Model 24965 (also referred to as a telemetry head) used in conjunction with the CareLink Network. The Reveal LINO ICM continues to have the same intended use when used with the LINQ Programmer system. The LINQ Programmer system provides the essential capabilities for programming, interrogating and managing the Reveal LINQ ICM in a clinical or hospital environment.
The LINQ Programmer system has no impact on the physical characteristics, materials, mechanical, electrical, hardware, components, firmware, operation, performance, and telemetry protocol of the Reveal LINQ ICM. There are no differences in the performance, features, materials, hardware, firmware, intended use or programmer-to- implantable device interface between the Reveal LINO ICM used with the LINO Programmer system versus the existing programmer software and hardware. The LINQ Programmer system is capable of interrogating and programming the Reveal LINO ICM like the existing programmer software and hardware.
Indications for Use
There are no changes to the cleared indications for use for the Reveal LINQ ICM Model LNQ11 when used with the LINQ Programmer Application and patient connector as compared to the Reveal LINQ ICM Model LNQ11 indications when used with existing programmer software and hardware.
The indication statement is as follows:
The Reveal LINQ ICM is an insertable automatically-activated and patient-activated monitoring system that records subcutaneous ECG and is indicated in the following cases:
- patients with clinical syndromes or situations at increased risk of cardiac arrhythmias o
6
- patients who experience transient symptoms such as dizziness, palpitation, syncope, . and chest pain that may suggest a cardiac arrhythmia
The device has not been tested specifically for pediatric use.
Technological Characteristics
The Reveal LINQ ICM consists of three major subassemblies which include the hermetically enclosed battery, hermetically enclosed electronics module, and molded header assembly. The battery is a custom D-shaped cell based on LiCFx chemistry and supports a 12-month shelf life and 3-year usable capacity. The Electronics Module contains the hybrid comprised of a printed circuit board with surface mount components on one side and an over molded stack on the other side which contains analog, digital and memory IC's along with capacitor arrays. The molded Header Assembly contains a Titanium Nitride coated sensing electrode, an embedded miniature RF antenna, suture hole, and a mounting bracket.
The Reveal LINO ICM will continue to use the same technology. It is designed to automatically record the occurrence of an arrhythmia in a patient, continuously senses the patient's subcutaneous ECG, and analyzes the timing of ventricular events to detect possible episodes of arrhythmia. The Reveal LINQ ICM has a small form factor, and uses Titanium, Parylene, Urethane, and Titanium Nitride coating on the sensing electrodes as body contacting materials.
The use of the LINO Programmer system to support the Reveal LINO ICM does not alter the existing technology of the Reveal LINQ ICM. Additionally, from the system perspective, the LINQ Programmer Application still communicates via an RF head (the patient connector) which in turn communicates with the Reveal LINQ ICM to program diagnostic settings and to extract data from the implantable device for viewing on either the LINO Programmer Application or the Medtronic CareLink Network. The patient connector utilizes the same telemetry protocol (Telemetry B) to communicate with the Reveal LINQ ICM; however, it utilizes Bluetooth technology to communicate with the mobile device, and has rechargeable battery-powered operation. The LINO Programmer Application utilizes existing infrastructure of the clinician's mobile device to run the programming application facilitating, portability and mobility, direct connectivity with CareLink via cellular and Wi-Fi, Bluetooth connectivity to communicate with the patient connector, software updates via publicly accessible channels (i.e. Google Play Store), and a user interface with workflows, streaming ECG waveform and marker display.
Summary of Testing
Testing was performed to demonstrate equivalency of the Reveal LINQ Model LNQ11 Insertable Cardiac Monitor with LINQ Programmer Application and patient connector to the Reveal LINQ ICM with existing programmer software and hardware. The Reveal LINQ ICM with LINQ Programmer Application and patient connector were subjected to the same use scenarios during testing as the Reveal LINO ICM with existing programmer software and hardware, thus supporting substantial equivalency. Testing included:
Reveal LINO (Model LNO11) Testing
System verification and system validation were completed with the Reveal LINQ Model LNQ11 Insertable Cardiac Monitor.
