This is a 510(k) premarket notification for a medical device, which seeks to demonstrate substantial equivalence to previously cleared devices. Therefore, the information provided focuses on comparative data rather than a standalone clinical study with acceptance criteria in the same manner as a de novo or PMA submission might require.

However, based on the provided text, we can infer some "acceptance criteria" related to magnetic resonance compatibility and how the study "proves" the device meets them.

1. Table of Acceptance Criteria and Reported Device Performance

Explanation: The "acceptance criteria" here are indirectly established by the selection of specific ASTM standards for magnetic resonance compatibility. The study "proves" the device meets these criteria by performing tests according to these standards and reporting that the "results demonstrated compatibility conditions." While the exact quantitative thresholds are not provided in this summary, the FDA's clearance implies that the performance met the requirements set by these recognized standards for MR safety.

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

• Sample Size for Test Set: Not specified. The document states that "non-clinical testing was conducted in alignment with the following standards." This usually means a set of representative devices or components are tested, but the specific number is not provided in this summary.
• Data Provenance: The nature of the tests (magnetic resonance compatibility) indicates laboratory testing of the devices themselves, rather than human subject data. Therefore, "country of origin of the data" and "retrospective or prospective" do not directly apply in the traditional sense of clinical studies. The tests were performed to demonstrate that the device materials and design are safe within an MR environment.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

This submission is for device clearance based on non-clinical (laboratory) testing for MR compatibility. Therefore, there were no experts used to establish ground truth for a test set in the clinical sense. The "ground truth" is governed by the objective measurements defined by the ASTM standards for MR compatibility.

4. Adjudication Method for the Test Set

Not applicable. As this is non-clinical laboratory testing, there is no adjudication method involving human interpretation or consensus. The data points are quantitative measurements against predefined ASTM standard limits.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No. An MRMC comparative effectiveness study was not done. This type of study is relevant for assessing the impact of AI on diagnostic performance with human readers, which is not the purpose of this submission. This submission is for the clearance of physical medical devices (spinal systems) and their magnetic resonance compatibility labeling.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done

No. A standalone algorithm-only performance study was not done. This submission concerns physical medical devices and their MR compatibility, not an algorithm.

7. The Type of Ground Truth Used

The "ground truth" for the non-clinical tests was defined by the specifications and limits within the cited ASTM standards (ASTM F2213, ASTM F2052, ASTM F2119, ASTM F2182) for magnetic resonance compatibility. These standards outline methodologies and acceptable thresholds for torque, displacement force, image artifacts, and heating.

8. The Sample Size for the Training Set

Not applicable. There is no "training set" in the context of this 510(k) submission, as it relates to physical device testing for MR compatibility, not machine learning or AI algorithm development.

9. How the Ground Truth for the Training Set was Established

Not applicable. As there is no training set, there is no ground truth to establish for it.

The fixation components of the system include plates, screws and connectors (hex nuts and inlays). These are available in a variety of sizes and lengths to accommodate differing patient anatomy.

The provided text describes a 510(k) premarket notification for a medical device called the "golden gate™ System," a spinal intervertebral body fixation orthosis. The notification focuses on establishing substantial equivalence to previously cleared predicate devices through performance data, specifically mechanical testing.

Here's an analysis of the acceptance criteria and study information based on your request:

1. Acceptance Criteria and Reported Device Performance

Note: The document does not explicitly state numerical acceptance criteria (e.g., minimum load bearing capacity in Newtons, or maximum displacement in millimeters). Instead, it relies on a comparative standard: performing as well as or better than the predicate devices when tested against the ASTM F1717 standard. This is a common approach for 510(k) submissions demonstrating substantial equivalence.

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

• Sample Size: The document does not specify a numerical sample size for the "worst case golden gate™ construct" tested. It refers to a "worst case" construct, implying that representative configurations of the device were tested. For mechanical testing, this typically involves a limited number of samples for each configuration to demonstrate compliance with a standard.
• Data Provenance: The study was a prospective mechanical laboratory study. The document does not provide details on the country of origin of the data beyond the sponsor being a German company (ulrich GmbH & Co. KG) with a US subsidiary (ulrich medical USA, Inc.). The testing was performed in accordance with ASTM F1717, an international standard.

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

This section is not applicable to this submission. The device is a mechanical implant, and its performance is evaluated through objective mechanical testing against a recognized standard (ASTM F1717), not through subjective interpretation by human experts or clinical ground truth.

4. Adjudication Method for the Test Set

This section is not applicable. The "test set" in this context refers to the physical devices undergoing mechanical stress tests. There is no human adjudication involved in interpreting these objective mechanical measurements.

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

This section is not applicable. An MRMC study is relevant for diagnostic devices or AI systems where human reader performance is being evaluated or compared. This submission pertains to a surgical implant, and its effectiveness is determined by mechanical stability and successful fusion, not diagnostic accuracy.

6. Standalone (i.e., algorithm only without human-in-the-loop performance) Study

This section is not applicable. The "golden gate™ System" is a physical medical device (spinal implant), not a software algorithm or AI system. Therefore, standalone algorithm performance is not relevant.

7. Type of Ground Truth Used

The "ground truth" for this device's performance is established by objective mechanical test results directly measured during the tests (e.g., load-to-failure, displacement, fatigue cycles) compared against the benchmark performance of predicate devices as per the ASTM F1717 standard.

8. Sample Size for the Training Set

This section is not applicable. This is a physical medical device, not a machine learning model. Therefore, there is no "training set."

9. How the Ground Truth for the Training Set Was Established

This section is not applicable, as there is no training set for this device.
