1. Table of Acceptance Criteria and Reported Device Performance

The document doesn't explicitly present a formal "acceptance criteria" table with pre-defined thresholds. Instead, it describes performance metrics that were measured and the results achieved, which implicitly serve as the "met criteria." The "Comments" column indicates whether the observed performance meets or aligns with expectations for substantial equivalence.

Performance Metric	Acceptance Criteria (Implicit)	Reported Device Performance	Comments
Ground-truth Accuracy	Expected to be low (e.g., < 1mm) and comparable to predicate/reference devices.	Statistically demonstrated as `< 1mm`	Meets implicit criterion. Demonstrates high accuracy essential for EP mapping systems.
Shift	Expected to be low (e.g., < 1mm).	`< 1mm`	Meets implicit criterion. Indicates stability of localization.
Drift	Expected to be low (e.g., < 2mm).	`< 2mm`	Meets implicit criterion. Indicates stability of localization over time.
3D Geometry Generation	Equivalent generation of 3D geometries compared with the predicate (CARTO 3 System).	Equivalent generation of 3D geometries compared with CARTO 3 System	Demonstrated equivalence to the predicate, indicating comparable functionality for creating anatomical models.
Map Generation (Voltage, LAT, Fractionation)	Equivalent performance compared with the reference (EnSite X System) for relevant maps.	Equivalent accuracy and performance compared with EnSite X System (using FlexAbility™ Ablation Cathether, Sensor Enabled™) for peak-to-peak voltage maps, Local Activation Time (LAT) maps, and fractionation maps.	Demonstrated equivalence to the reference device for key electrophysiological maps, ensuring comparable diagnostic information. Note: NeuTrace does not include impedance maps, which were present in reference devices, but this is stated as not required for their intended use.
System Performance (Overall)	Meets all specifications and user requirements. Operates as intended for catheter-based cardiac EP procedures.	Passed all testing and met all design specifications and user requirements.	Overall system performance verified through comprehensive testing.
Software Verification & Validation	Compliant with software development standards and functional requirements.	Performed	Assures software quality and reliability.

Cybersecurity Risk Management & Testing	Compliant with cybersecurity standards for medical devices.	Performed	Addresses potential cybersecurity vulnerabilities.
EMC/EMI Testing	Compliant with IEC 60601-1 and IEC 60601-1-2 standards.	Performed per IEC 60601-1 and IEC 60601-1-2	Ensures electromagnetic compatibility and safety.
NeuTrace-EnSite accuracy and equivalency testing	Accuracy and performance equivalent to EnSite X System.	Performed; demonstrated equivalent accuracy and performance.	Confirms performance parity with a key reference device.
NeuTrace-CARTO geometry and mapping equivalency analyses	Geometry and mapping generation equivalent to CARTO 3 System.	Performed; demonstrated equivalent generation of 3D geometries and maps.	Confirms performance parity with the predicate device.

2. Sample Size Used for the Test Set and Data Provenance

Sample Size for Test Set: The document does not specify the exact sample size (e.g., number of cases, number of data points) used for the bench testing or the GLP animal study. It only states that a GLP animal study was performed.
Data Provenance:
- Country of Origin: Not specified.
- Retrospective or Prospective: Not specified, but a "GLP animal study" implies prospective data collection under Good Laboratory Practice principles. Bench testing is inherently prospective.

3. Number of Experts Used to Establish Ground Truth and Qualifications

The document does not provide any information on the number of experts used or their qualifications for establishing ground truth, especially for the animal study.
The "ground-truth accuracy" results (e.g., < 1mm) suggest that a highly precise physical measurement system was used as the ground truth, rather than human expert interpretation of images or data.

4. Adjudication Method for the Test Set

The document does not describe any adjudication method (e.g., 2+1, 3+1 consensus) for the test set. Given the context of a 3D electroanatomical mapping system and the nature of the performance metrics (accuracy, shift, drift, geometric equivalence), the ground truth seems to be derived from physical measurements or direct comparisons to established systems/methods rather than interpretations requiring human consensus.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No MRMC comparative effectiveness study was done involving human readers improving with AI vs. without AI assistance.
This device is an EP mapping system, providing objective electrical and anatomical data, not an AI-assisted diagnostic imaging interpretation tool that would typically undergo MRMC studies. Its function is to provide information for the clinician, not to make a diagnosis or interpretation in place of one.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance)

The performance data presented (accuracy, shift, drift, geometry, and map generation) are inherently standalone performance of the system's ability to localize and generate data. The system itself generates the maps and measurements; it's not a human-in-the-loop scenario where a human is assisted by AI to perform a task. The NeuTrace system provides the foundational spatial and electrical data directly.

7. Type of Ground Truth Used

The type of ground truth used appears to be based on highly precise physical measurements and direct comparisons to established, validated predicate/reference systems.
- For accuracy, shift, and drift: Likely precise physical measurement systems (e.g., optical tracking, high-precision fiducial markers) were used in conjunction with the device's own measurements.
- For 3D geometry and map generation: The ground truth was established by direct comparison to the performance of the predicate (CARTO 3 System) and reference (EnSite X System) devices, which are already considered established and validated standards in the field.

8. Sample Size for the Training Set

The document does not specify any sample size for a training set. This makes sense given that the NeuTrace EP Mapping System v.2.1 is described as an "advanced 3D electroanatomical mapping (EAM) and analysis system" that relies on "Magnetic-based localization" and "derived voltage and time metric overlays." This suggests an algorithmic or physics-based system, rather than a machine learning/AI system that requires a dedicated training set to learn from data.

9. How Ground Truth for the Training Set Was Established

Since no training set is mentioned (implying a non-ML/AI driven system), there is no information provided on how ground truth for a training set was established.
