The document describes an insertable cardiac monitor that automatically detects arrhythmias based on ECG signals, but there is no mention of AI or ML in the device description, performance studies, or key metrics. The auto-activation feature is likely based on pre-defined thresholds or algorithms rather than learned patterns.
No.
Explanation: The device is an insertable cardiac monitor designed to record subcutaneous ECG and identify cardiac arrhythmias. While it helps detect conditions that may require therapy, it does not directly treat or provide therapy itself.
Yes
The device records subcutaneous ECG and is indicated for patients at risk of cardiac arrhythmias or experiencing symptoms that may suggest a cardiac arrhythmia, to detect and classify different types of arrhythmias. This function of detecting and classifying medical conditions directly aligns with the definition of a diagnostic device.
No
The device description explicitly states it is a "small, leadless implantable device" with "two electrodes on the body of the implantable device" that continuously monitor ECG. This indicates a significant hardware component. While there is associated software (Reveal LINQ Mobile Manager App), the core medical device is the implantable hardware.
Based on the provided information, the Reveal LINQ ICM is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to provide information about a person's health. These tests are performed outside of the body (in vitro).
- Reveal LINQ ICM 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.
- No Sample Analysis: The device does not analyze samples taken from the body. It directly measures a physiological signal (ECG).
Therefore, the Reveal LINQ ICM falls under the category of an implantable medical device for monitoring physiological signals, not an In Vitro Diagnostic device.

The Reveal LINQ ICM Model LNQ11 with existing Reveal LINQ Mobile Manager App Model MSW001 and patient connector Model 24965 was initially cleared via a 510(k) application K150614 on 06AUG2015. This submission is to add an app (Model MSW002) to the Reveal LINQ Mobile Manager for use on iOS mobile devices. The Reveal LINQ Mobile Manager for iOS devices is comprised of the Reveal LINO Mobile Manager App Model MSW002 installed on a clinician's off-the-shelf non-medical iOS 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 Reveal LINO Mobile Manager App Model MSW002 and patient connector Model 24965. The Reveal LINQ Mobile Manager App Model MSW002 and patient connector Model 24965 provide the essential capabilities for programming, interrogating and managing the Reveal LINQ ICM in a clinical or hospital environment.
The Reveal LINO Mobile Manager App Model MSW002 and patient connector Model 24965 have no impact on the physical characteristics, materials, mechanical, electrical, hardware, components, firmware, operation, performance, and telemetry protocol of the Reveal LINO ICM. There are no differences in the performance, features, materials, hardware, intended use or programmer-to- implantable device interface between the Reveal LINQ ICM used with the Reveal LINQ Mobile Manager App Model MSW002 and patient connector Model 24965 versus the existing Reveal LINO Mobile Manager App Model MSW001 and patient connector Model 24965. The Reveal LINO Mobile Manager App Model MSW002 and patient connector Model 24965 are capable of interrogating and programming the Reveal LINQ ICM like the existing Reveal LINQ Mobile Manager App Model MSW001 and patient connector Model 24965.
Indications for Use
There are no changes to the cleared indications for use for the Reveal LINO ICM Model LNO 1 when used with the Reveal LINQ Mobile Manager App Model MSW002 and patient connector Model 24965 as compared to the Reveal LINQ ICM Model LNQ11 indications when used with the existing Reveal LINQ Mobile Manager App Model MSW001 and patient connector Model 24965.
The indication statement is as follows:
The Reveal LINO 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 ●
- . 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 Reveal LINO Mobile Manager App Model MSW002 and patient connector Model 24965 to support the Reveal LINQ ICM does not alter the existing technology of the Reveal LINQ ICM. Additionally, from the system perspective, the Reveal LINQ Mobile Manager App 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 Reveal LINQ Mobile Manager App 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 Low Energy technology to communicate with the mobile device, and has rechargeable battery-powered operation. The Reveal LINQ Mobile Manager App 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 Low Energy connectivity to communicate with the patient connector, software updates via publicly accessible channels (i.e. Apple App 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 Reveal LINO Mobile Manager App Model MSW002 and patient connector Model 24965 to the Reveal LINQ ICM with the existing Reveal LINQ Mobile Manager App Model MSW001 and patient connector Model 24965. The Reveal LINQ ICM with Reveal LINQ Mobile Manager App Model MSW002 and patient connector Model 24965 were subjected to the same use scenarios during testing as the Reveal LINO ICM with the existing Reveal LINQ Mobile Manager App Model MSW001 and patient connector Model 24965, thus supporting substantial equivalency.
