The device records cardiac information in response to automatically detected arrhythmias and patient-initiated activation or markings. The device is designed to automatically record the occurrence of an episode of arrhythmia in a patient. Note: Arrhythmias are classified as tachyarrhythmia, bradyarrhythmia, pause, atrial tachyarrhythmia, or atrial fibrillation. Patients may also manually record symptoms. In order to manually record symptoms, the patient will also need either the MyCareLink Heart App (patient app on mobile device) or the Patient Assistant Model PA97000. The patient can use the MyCareLink Heart App or the Patient to manually record his or her cardiac rhythm while experiencing or immediately after a symptomatic event. LINQ II ICM and this submission includes the following accessories: LINO Tool Kit Model LNO22TK, Reveal LINQTM Mobile Manager Model MSW002, Device Command Library Model 2692, and Instrument Command Library Model 2691. ### Accessories Subject to this Submission - The LINQ Tool Kit Model LNQ22TK includes two implant tools: The Incision Tool is used to make a small incision through the patient's skin: and the Insertion Tool is used to insert the device through the incision and into the patient's body at the desired location. - The Reveal LINQ™ Mobile Manager (LMM) Model MSW002 is the programmer ● designed as a mobile app that communicates with the Reveal LINQ and LINQ II ICM devices via the existing model 24967 telemetry head. - The 2692 Device Command Library (DCL) software is a component of the Data ● Transformation Services subsystem of the CareLink Network. This software is responsible for understanding command status, implant device state within CareLink, and the initiation of commands for the implanted device. - The 2691 Instrument Command Library (ICL) software is the logic and data files required for remote programming. ## Indications for Use Aside from the name of the device, there are no changes as compared to the Reveal LINQ ICM Indications for Use as a result of this submission. The Indications for Use are provided below: The LINO II 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 LINO II ICM consists of a hybrid substrate that is made of sapphire. The sapphire provides part of the implantable hermetic enclosure, integrates the feedthroughs directly into the substrate, {5}------------------------------------------------ and provides a substrate for component attachment/interconnect. The antenna and sense electrodes are titanium foil laser bonded to the outside of the sapphire substrate and connected directly to the embedded feedthroughs. The sense electrodes will be coated with sputtered titanium nitride. The sapphire will be laser bonded to the titanium battery cover, which provides the complete hermetic enclosure. The battery is Lithium anode, silver vanadium oxide/carbon monofluoride cathode with a capacity of 167 mAh. The LINO II ICM will continue to use the same technology. It is designed to automatically record the occurrence of an arrhythmia in a patient, continuously sense the patient's subcutaneous ECG, and analyze the timing of ventricular events to detect possible episodes of arrhythmia. The LINQ II ICM has a small form factor, and uses Sapphire, Titanium, Parylene, and Titanium Nitride coating on the sensing electrodes as body contacting materials. When compared to the predicate device, the existing Reveal LINQ ICM (most recently cleared by FDA under K162855), the LINQ II ICM has the same: - Indications for use - · Operating principle - Device functionality - · Biological safety When compared to the predicate device, the existing Reveal LINQ ICM (most recently cleared by FDA under K162855), the LINQ II differs as follows: - · 4.5-year longevity - · Bluetooth Low Energy (BLE) technology to enable communication with mobile devices via a mobile application. - · The LINO II ICM includes minor changes to enhance the arrhythmia detection algorithms and diagnostics which include pause detection and PVC detector. - · The insertion tool is being updated to accommodate the LINQ II device form factor. - · CareLink Network enhancements to support the LINQ II device remote follow-up. This includes updates to the Instrument Command Library and Device Command Library. - · Reveal LINO Mobile Manger updates to support LINO II ICM. ### Substantial Equivalence Technological differences between the subject and predicate devices have been evaluated through bench and animal testing. The LINO II ICM is substantially equivalent to the predicate device, the existing Reveal LINQ ICM (cleared by FDA under K162855) based on comparisons of device functionality, technological characteristics, and indications for use. ### Summary of Testing Firmware testing, design verification, system verification, and system design validation testing were performed to demonstrate that the subject device, the LINQ II ICM, met established {6}------------------------------------------------ performance criteria to support equivalency to the referenced predicate device, the existing Reveal LINQ ICM (cleared by FDA under K162855). - . Firmware design verification: This testing was made up of two parts: verification of the individual design artifacts (firmware units) associated with the development and release of the firmware; and verification of the finished firmware product (implemented design) to confirm that it meets the associated input requirements. - Firmware regression testing: This testing of unchanged firmware was performed to ● ensure that no unintended side effects were introduced. - . Verification testing: - · Mechanical - · Electrical - · Electromagnetic compatibility (EMC) and electrical safety - · Sterilization - · Biocompatibility - · MRI Compatibility - · Sensing and detection performance validation - · Packaging testing - Human Factors - · Security - System testing: This testing was performed on the subject device (LINO II) and its . accessories which included system verification testing and system validation testing. System design verification ensured that the proposed modifications did not impact the existing system level design inputs. System design validation confirmed through a combination of test and analysis that the stakeholder needs and intended use continued to be met by the subject device. {7}------------------------------------------------ The following standards and guidance documents were used for development and testing of the LINQ II device: | Standard<br>Number | Standard<br>Organization | Recognition<br>Number | Standard Title | |-------------------------------------------------------------|--------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 14971:2012 | ISO | 5-40 | Medical Devices - Application of Risk Management to<br>Medical Devices | | 62304:2006 | IEC EN | 13-32 | Medical device software - Software life-cycle processes | | EC57:1998 | AANSI/AAMI | 3-118 | Testing and Reporting Performance Results of Cardiac<br>Rhythm and ST Segment Measurement Algorithms | | 62366:<br>2007/(R)2013 | AAMI/ANSI/<br>IEC | 5-114 | Medical devices - Application of usability engineering to<br>medical devices | | 15223-1:2012 | ISO | 5-117 | Medical devices — Symbols to be used with medical<br>device labels, labeling, and information to be supplied -<br>Part 1: General requirements | | 10993-1:<br>2009/(R)2013 | AAMI/ANSI/<br>ISO | 2-220 | Biological evaluation of medical devices.
