# BioTracker 2.0 (K253306) _Biotracker, LLC · Jun 26, 2026 · CV · SESE_ **Canonical URL:** https://fda-staging.innolitics.com/device/K253306 ## Device Facts - **Applicant:** Biotracker, LLC - **Decision Date:** Jun 26, 2026 - **Decision:** SESE - **Submission Type:** Traditional - **Review Panel:** CV - **Attributes:** Software as a Medical Device ## Indications for Use BioTracker 2.0 is software intended to acquire, display, store, organize, and report physiological data obtained from compatible legally marketed physiological acquisition devices for review by licensed healthcare professionals. The software acquires physiological measurements including oxygen saturation (SpO₂), pulse rate, systolic blood pressure, diastolic blood pressure, and mean arterial pressure (MAP). The software performs mathematical analysis of the acquired physiological measurements and derived pulse waveform data to calculate the following parameters: - Ankle-Brachial Index (ABI) (right and left) - Root Mean Square of Successive Differences (RMSSD) - Standard Deviation of Normal-to-Normal Intervals (SDNN) - Percentage of Successive NN Intervals Differing by More Than 50 ms (pNN50) - Low Frequency/High Frequency Ratio (LF/HF) - Reflection Index (RI) - Pulse Wave Amplitude Ratio (PWAR) - Stiffness Index (SI) Each calculated parameter is displayed individually together with its corresponding unit of measure. BioTracker 2.0 performs mathematical analysis and presentation of physiological data only. The software does not provide diagnostic interpretations, disease classification, patient risk scores, comparative indicators, alarms, treatment recommendations, or aggregated clinical assessments. Interpretation of the reported physiological measurements and calculated parameters is the responsibility of the licensed healthcare professional. BioTracker 2.0 is intended for spot-check physiological assessments only. It is not intended for continuous physiological monitoring, real-time patient monitoring, life-support applications, or physiological alarm generation. BioTracker 2.0 is intended for use in primary care practices, family medicine practices, internal medicine practices, outpatient physician offices, and outpatient healthcare clinics. BioTracker 2.0 is intended for use by licensed healthcare professionals on adult patients 18 years of age or older.

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 available 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. Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled 'Deciding When to Submit a 510(k) for a Change to an Existing Device' U.S. Food & Drug Administration 10903 New Hampshire Avenue Silver Spring, MD 20903 www.fda.gov {1} K253306 - Jorge Millan Page 2 (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

These devices collect physiological signals which are transmitted to the BioTracker software. The software processes these inputs using validated algorithms to calculate parameters such as HRV and ABI. Processed data is stored in a local database linked to individual patient records under a HIPAA-compliant system. The system displays results and generates structured reports including numerical values and waveform analysis. Each output is presented individually with its unit; the software assigns no qualitative category, score, comparative indicator, or interpretive classification, and does not combine, average, or Page 2 of 7 {7} K253306 - BioTracker LLC - BioTracker 2.0 BioTracker BioTracker 2.0 510K Summary – June 26, 2026 K253306 aggregate measurements. Reports can be printed, stored, or exported locally (PDF). The user interface guides the clinician through calibration, test execution, and reporting. ## Non-Clinical Data: Non-clinical product evaluation to demonstrate safety and effectiveness was conducted. Non-clinical testing includes: - Risk Management: ISO 14971:2019 - Software verification and validation testing were conducted on the BioTracker 2.0 system and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices."

Both are standalone PC-based software applications that acquire, process, display, and store physiological data obtained from compatible FDA-cleared measurement devices, and both perform deterministic mathematical analysis of the photoplethysmographic (PPG) waveform to produce pulse-waveform-derived indices and heart-rate-variability (HRV) metrics. In both systems, the software provides healthcare professionals with numeric values such as oxygen saturation (SpO₂), pulse rate, HRV metrics, and pulse-waveform-derived indices, without independent diagnosis or interpretation. The Microlife WatchBP Office Central (secondary predicate) supports the Ankle-Brachial Index (ABI) output, which it calculates and validates per ISO 81060-2. Non-clinical performance testing and usability validation confirm that safety and effectiveness are comparable. - Differences between BioTracker 2.0 and the Oxi-W System relate mainly to the graphical user interface and the framing of outputs. Unlike the Oxi-W System, BioTracker 2.0 provides no physiological alarms and presents outputs only as numeric values, without relating them to autonomic-nervous-system function or microvascular condition; BioTracker 2.0 is therefore a narrower and more conservative device. These differences do not raise any new questions of safety or effectiveness. Both systems rely exclusively on FDA-cleared acquisition devices, ensuring that device-level performance and safety have already been established. ### Conclusion: Based on the comparison of intended use, technological characteristics, performance, and safety, the BioTracker 2.0 Software is substantially equivalent to the primary predicate device, Oxi-W System (K200141), with the Microlife WatchBP Office Central (K171937) as a secondary predicate supporting the Ankle-Brachial Index output. BioTracker 2.0 relies on FDA-cleared accessories (Pulse Oximeter CMS50E, 510(k) K090671, and Blood Pressure Monitor BP2/BP2A, 510(k) K193348) to obtain physiological data. The differences identified, including updates in operating system compatibility, improvements in the graphical user interface, and expanded reporting capabilities, do not raise new questions of safety or effectiveness. These differences represent software usability and performance enhancements that have been verified and validated, while maintaining the same technological principles as the predicate device. Accordingly, the BioTracker 2.0 Software demonstrates equivalent safety and effectiveness to the predicate device, and no new risks are introduced.
