Indications for Use
CariCloud is a software device used by operators to evaluate attenuation in the coronary arteries and surrounding tissue in CCTA images. CariCloud is to be used by trained operators. CariCloud analysis results are to be used by Healthcare Professionals and may assist in diagnosis. CariCloud analysis results are indicated for use for all patients referred for CCTA imaging.
Device Story
CariCloud v1.0 is a prescription software device for display, manipulation, and quantification of previously acquired CCTA images. Trained operators download datasets from remote systems; initiate and oversee image analysis; intervene to correct processing errors. Device performs automatic and manual centerline extraction; vessel analysis; automatic and manual segmentation of structures; linear, area, and volume measurements. Output includes a summary report with qualitative and quantitative analysis for healthcare professionals to assist in diagnosis. Used in clinical settings; operates on any system supporting Chrome browser. Benefits include standardized assessment of coronary artery attenuation.
Clinical Evidence
Bench testing only. Performance evaluated via inter-operator and intra-operator variability studies comparing CariCloud to the predicate device. ICC values for all measures (PFA, TVOI-A, TVOI-V, TROI-A) were excellent (ICC > 0.96) for both devices, with a maximum difference in ICC of 0.017. No significant difference in variability between devices.
Technological Characteristics
Software-only device; operates via Chrome browser. Features include automatic/manual centerline extraction, segmentation, and image assessment tools (MPR, 3D triangulation, CPR). Data input via manual keyboard/mouse/command line. Output stored as DICOM SC. Cybersecurity and data security measures implemented. Software level of concern: Moderate.
Indications for Use
Indicated for all patients referred for CCTA imaging to evaluate attenuation in coronary arteries and surrounding tissue. For use by trained operators; results intended for healthcare professionals to assist in diagnosis.
Regulatory Classification
Identification
A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Dear Mr. Davis:
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.

### PERFORMANCE DATA VI.
# Software Verification and Validation Testing
Software verification and validation testing were conducted 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." The software level of concern for CariCloud v1.0 is Moderate, as per FDA's quidance document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". This device does not control a life supporting or life-sustaining device, does not control the delivery of a potentially harmful energy, does not control the delivery of treatment, does not provide diagnostic information, and does not provide any vital signs monitoring. The hazard analysis identifies the potential software-related risks of using the device, and the mitigations implemented.
## Performance Testing
CariCloud v1.0 software has been developed and tested in accordance with the Caristo Diagnostics Design Control processes and has been subject to extensive safety and performance testing. Nonclinical verification and validation testing has been performed to demonstrate that CariCloud v1.0 meets its design requirements and intended use. Software verification has been conducted at unit and system integration levels. A risk analysis was performed to document the risks associated with the use of the CariCloud v1.0 software product with all identified risks being mitigated. Cybersecurity and data security testing has been conducted to verify that data and patient protected health information security measures are included in the design of the software.
Based on the Verification and Validation testing that has been conducted. CariCloud v1.0 is substantially equivalent to the predicate device.

Below "Caristo" is the word "diagnostics" in a smaller, light gray font. To the left of the word "Caristo" is a stylized graphic consisting of three concentric arcs in different colors: yellow, orange, and red.
# Performance Testing - Inter-operator and Intra-operator Variability
For each device, ICC values were calculated between individual results of each read by each operator on each device for each measure based on an average-rating, absolute-agreement, 2-way mixedeffects model. Theses are shown in the table below.
| | PFA | | | TVOI-A | | | TVOI-V | | | TROI-A | | |
|---------------------|-------------|-------------|-------------|-------------|-------------|-------------|-------------|-------------|-------------|-------------|-------------|-------------|
| ICC | Reader<br>1 | Reader<br>2 | Reader<br>3 | Reader<br>1 | Reader<br>2 | Reader<br>3 | Reader<br>1 | Reader<br>2 | Reader<br>3 | Reader<br>1 | Reader<br>2 | Reader<br>3 |
| Predicate<br>Device | 0.999 | 0.998 | 0.999 | 0.986 | 0.983 | 0.985 | 0.988 | 0.991 | 0.973 | 1.0 | 1.0 | 1.0 |
| New<br>Device | 0.997 | 0.997 | 0.994 | 0.987 | 0.971 | 0.982 | 0.971 | 0.986 | 0.969 | 1.0 | 0.998 | 1.0 |
# Comparison of Intra-Operator Agreement achieved for Each Measure on Each Device:
For all measures, the intra-operator agreement achieved on both the predicate device and the new device for each operator was excellent (ICC greater than 0.96) with a maximum difference in ICC between the two devices was 0.017.
There was no significant difference between the inter-operator variability and intra-operator variability results attained on the two devices.
### CONCLUSIONS VII.
CariCloud v1.0 has the same intended use and the same or similar technological characteristics as the predicate device, TeraRecon iNtuition. The minor differences in the indications do not alter the intended use of CariCloud v1.0 and do not raise any new questions of safety or effectiveness. For this reason, CariCloud v1.0 is substantially equivalent to the predicate device.
