Dear Behn Bryan:
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 (the 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 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.

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
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 (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

| Confounders | For SonoLyst 1st Trimester the following confounder is used: the algorithmic performance is tested on two sub data sets: 1) data acquired with transabdominal probes 2) data acquired with transvaginal probes. By choosing transabdominal vs transvaginal probes as confounder for the data analysis, the robustness of the algorithm against the influence of the abdominal wall, the transducer geometry and frequency is evaluated. For both subgroups the acceptance criteria are met. This demonstrates the generalization performance of the algorithm. Subgroup and potential confounders analysis has been completed were appropriate and data allows. All patients within the dataset includes pregnancies between 11 and 14 weeks of gestation, with no known fetal abnormalities at the time of imaging, in line with the intended use.

Where collected, patient age is grouped into <20, 20-29, 30-39, 40-49, >50. The data set contains known patient ages from <20 till 30-39 and has been limited to reproductive ages of at least 18 years of age.
Data was collected from 396 patients for CL2 evaluation, with 201 (51%) patients from USA sites and 195 (49%) from European sites.
From our earlier evaluation across the probe groups, we also conducted a subset evaluation across different regions. In all cases the confidence intervals cross zero, indicating no statistically significant difference. These findings demonstrate that the algorithm performs consistently across regions.

| Truthing process for test datasets | In general for Sonolyst Software:
To ensure the quality of the curated data for verification, the following strategy is employed:
1. The images were curated (sorted and graded) by a single sonographer
2. The images were sorted and graded by SonoLyst IR/X First Trimester.
This process resulted in some images being reclassified during sorting.
3. The sorting process resulted in some images being reclassified based upon the majority view of the panel. Where they differed from the ground truth, the graded images from step 1 were reviewed by a 5-sonographer review panel, in order to determine the grading accuracy of the system
especially for C1-6-D probe impmentation:
A standardized imaging protocol was used based on internationally recognized guidelines to ensure consistency and quality across all scans. Specifically, the following sources were used to inform the protocol: | | |
