No
The document describes automated detection of arrhythmias based on pre-defined classifications (AT/AF, bradyarrhythmia, pause, ventricular tachyarrhythmia) and mentions firmware regression and design verification testing, but does not mention AI or ML algorithms for detection or analysis.
No.
The device is an insertable cardiac monitor that records ECG and detects arrhythmias; it does not provide any therapy or treatment.
Yes
The device is described as an "insertable automatically-activated monitoring system that records subcutaneous ECG" to detect and record arrhythmias, which are diagnostic indicators of heart conditions. Its intended use is to monitor patients at risk of cardiac arrhythmias or those experiencing symptoms that may suggest a cardiac arrhythmia, directly supporting a diagnostic process.
No
The device description explicitly states it is a "small, leadless device that is typically implanted under the skin" and has "Two electrodes on the body of the device". This indicates a physical hardware component, not a software-only device.
Based on the provided text, 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 examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done 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.
The device's function and how it obtains information about the patient's health clearly fall outside the definition of an In Vitro Diagnostic. It is an in vivo (within the living body) diagnostic and monitoring device.

Intended Use / Indications for Use
The Reveal LINQ ICM is an insertable automatically-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

Device Description
The Reveal LINQ Model LNQ11 Insertable Cardiac Monitors (ICM) is designed to automatically 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 device that is typically implanted under the skin, in the chest. Two electrodes on the body of the device continuously monitor the patient's subcutaneous ECG.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Firmware regression testing, design verification and system design validation testing were performed to demonstrate the Reveal LINQ ICM meet established performance criteria to support equivalency to the referenced predicate device.
Performance Testing - Bench
- Firmware Regression Verification Testing. Verification testing performed for the Reveal LINQ Firmware with LINQ RRT modification and minor enhancements is complete. All 870 regression tests were executed and passed.
- Design Verification. No system or product level requirements were modified by this submission. Therefore, design verification was completed by verifying similarity to a previous design. The design outputs meet the design inputs based on: system and finished device similarity to the previous design(s), verification of the previous design(s), verification of no unintended changes to the current design(s), and verification of no unintended RAMware/firmware interactions within the finished device. All acceptance criteria have been met. The Reveal LINQ System and Reveal LINQ Insertable Cardiac Monitor are considered verified against their design input requirements.
- System Design Validation - System Design Validation Plan, activities fell into two general categories: analyses and test execution. Test protocols were developed to provide coverage of the aspects of the system being validated against the design input requirements and risk control measures being validated.
The results of the above testing met the specified acceptance criteria and did not raise new safety or performance issues. Therefore, the modifications made to the Reveal LINQ Model LNQ11 Insertable Cardiac Monitor described in this submission result in a device that is substantially equivalent to the predicate.
