The LUX-Dx Insertable Cardiac Monitor (ICM) is intended to monitor and record subcutaneous ECG (S-ECG) for the clinical evaluation and diagnosis of cardiac arrhythmias. The LUX-Dx is indicated for use in patients that have a known heart condition, are at risk of developing an abnormal heart rhythm, or have symptoms that may suggest a heart condition such as dizziness, palpitations, syncope, chest pain, and/or shortness of breath.
The LUX-Dx has not been tested specifically for pediatric use.
The LUX-Dx ICM sensor device (Model M301) evaluates S-ECG waveform data for indications of cardiac arrhythmias and "marks" the S-EG signal for clinical presentation when the algorithm criteria are met. The device is inserted into the subcutaneous layer of the fourth intercostal space of the left chest wall. The sensor device is powered by an integrated battery. The electrodes used for detecting the S-ECG signal are located on each end of the sensor device, in the header and at the battery. The LUX-Dx system includes the following main components:
- LUX-Dx™ sensor device a subcutaneously-implanted sensor device for cardiac arrhythmia event ● data collection and transmission. In addition, symptom events are collected and transmitted from the sensor device.
- Mobile Monitor (MM) mobile applications (myLUX™ Patient app and LUX-Dx™ Clinic Assistant . app) running on an OTS mobile device that communicates with the LUX-Dx sensor device (using Bluetooth Low Energy (BLE)) and the LATITUDE server (using cellular/Wi-Fi) for collection and transmission of event, patient, and device data.
- . LATITUDE Clarity™ server - a server that communicates with the Mobile Monitor for bidirectional data transmission and provides web access for clinicians to perform remote monitoring activities and manage general patient and system parameters and workflow activities.
- . System Accessories- for insertion of the sensor device, an insertion tool and incision tool are provided. In addition, a magnet is provided to initiate sensor/MM app communication.
The provided text describes the LUX-Dx Insertable Cardiac Monitor (ICM) and its substantial equivalence to a predicate device, but it does not contain specific acceptance criteria, detailed study designs, or performance metrics to fill out a table as requested.
The document is a 510(k) summary filed with the FDA, primarily addressing regulatory compliance and substantial equivalence to a predicate device (Medtronic Reveal LINQ LNQII). It lists various types of performance testing, such as "Algorithm Validation" and "LUX-Dx GLP and non-GLP studies," but it does not provide the results, acceptance criteria for these results, or the methodologies (e.g., sample sizes, ground truth establishment, expert qualifications, adjudication methods).
Therefore, I cannot fulfill your request for:
- A table of acceptance criteria and reported device performance.
- Sample sizes used for the test set.
- Data provenance.
- Number of experts used to establish ground truth and their qualifications.
- Adjudication method.
- Information on MRMC comparative effectiveness studies or effect sizes.
- Information on standalone algorithm performance.
- Type of ground truth used.
- Sample size for the training set.
- How ground truth for the training set was established.
The document states that "Boston Scientific performed safety risk management activities, design verification, design validation, and usability testing to demonstrate that the LUX-Dx system is substantially equivalent to the predicate device." It also lists "Algorithm Validation" as a type of performance testing. However, the details of this algorithm validation, including specific acceptance criteria and performance metrics, are not present in this public 510(k) summary. These details would typically be found in direct study reports, which are not included here.

Dear Melissa Klamerus:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for
{1}------------------------------------------------
devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medicaldevices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn).
