• Adjudication Method: Not applicable. This is mechanical testing data, not human-interpreted data. Results are quantified using laboratory equipment.

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

• MRMC Study Done: No. This type of study is for evaluating the impact of a diagnostic or assistive AI device on human reader performance. This submission is for an implantable medical device, not a diagnostic or AI-driven system.

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

• Standalone Study Done: No. This also refers to AI algorithm performance, which is not relevant to this mechanical device submission.

7. Type of Ground Truth Used

• Type of Ground Truth: Engineering standards and measurements of mechanical properties. The "ground truth" is adherence to established, validated mechanical test methods (ASTM F1717-18) that ensure the device is "substantially equivalent" in performance to predicate devices.

8. Sample Size for the Training Set

• Sample Size for Training Set: Not applicable. This concept applies to machine learning models. The manufacturing process of UNiD™ Patient Specific Rods involves patient-specific design (i.e., custom bending for one specific patient based on their anatomy), but this is not an AI "training set."

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

• How Ground Truth for Training Set Was Established: Not applicable. No "training set" in the machine learning sense is used here. For the patient-specific rods, the "ground truth" for each rod's design is the specific patient's anatomical requirements, which are determined via medical imaging and planning, not a training set.

This looks like a 510(k) submission summary for a spinal system, not a device that uses AI/ML for diagnostic or prognostic purposes, which is typically where the detailed acceptance criteria and study design information you're asking for would be found.

The document describes a mechanical spinal system and its instruments, focusing on substantial equivalence to predicate devices based on design, intended use, indications for use, and mechanical testing. It does not contain information about AI-driven performance, ground truth establishment, expert adjudication, or human-in-the-loop studies.

Therefore, I cannot provide the information requested in your bullet points because the provided text does not contain it. The acceptance criteria mentioned refer to mechanical performance tests for the spinal implants and instruments, not diagnostic performance of an AI algorithm.

Specifically:

• 1. A table of acceptance criteria and the reported device performance: The document states that "For subject devices that are tested have met the predetermined acceptance criteria for all tests." The tests are identified as ASTM F1798 (Axial Grip, Axial Torsion, Flexion Extension Static, Flexion Extension Fatigue) and ASTM F1717 (Static Compression, Static Torsion, Compression Fatigue). However, the specific quantitative acceptance criteria (e.g., maximum deflection, fatigue cycles survived) and the exact reported performance values are not detailed in this summary.
• 2. Sample sized used for the test set and the data provenance: Not applicable in the context of mechanical testing of physical implants. The "test set" here refers to the physical devices undergoing mechanical stress tests.
• 3. Number of experts used to establish the ground truth...: Not applicable. Ground truth for an AI device is clinical truth, not mechanical test results.
• 4. Adjudication method...: Not applicable.
• 5. If a multi reader multi case (MRMC) comparative effectiveness study was done...: Not applicable.
• 6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
• 7. The type of ground truth used: Not applicable for mechanical spinal implants. The "ground truth" for these tests would be the physical properties and structural integrity of the materials and design under specified loads.
• 8. The sample size for the training set: Not applicable (no AI/ML training is described).
• 9. How the ground truth for the training set was established: Not applicable.

In summary, this document pertains to a traditional medical device (spinal hardware) and confirms its substantial equivalence through mechanical testing, not through clinical performance evaluation of an AI/ML algorithm.

The subject CD HORIZON™ Spinal System consists of non-sterile domino connectors, made of Titanium Alloy, that are used to provide the surgeon with an efficient construct extension as well as connection options for multi-rod spinal constructs. The subject CD HORIZON™ Spinal System includes 1. Non-sterile Domino connectors 2. Trays and lid

The provided text is a 510(k) Summary for the Medtronic CD HORIZON™ Spinal System. It describes the device, its indications for use, and a comparison to predicate devices, focusing on the substantial equivalence argument for non-sterile domino connectors.

However, the document does not contain information about acceptance criteria or a study that proves the device meets specific performance criteria in the context of AI/ML or diagnostic performance.

The "Performance Data" section explicitly states:

"The purpose of this submission is to take the existing sterile domino connector designs, cleared in the predicate 2, and provide them non-sterile. The subject domino connectors are being created to provide additional rod connector options for surgeon convenience. No design changes have been made to the subject devices as a result of this submission. The subject devices remain identical to the designs cleared in the predicate 2 with the same intended use, materials, and fundamental technology. As a result, the subject CD HORIZON™ Spinal System does not represent a new worst case; therefore, no new bench performance testing is warranted."

And regarding biocompatibility, it states:

"Identical to the predicate devices, the subject domino connectors are made of Titanium Alloy. This material is considered biocompatible due to its long history of clinical use in medical devices."

Based on this information, the device discussed (CD HORIZON™ Spinal System domino connectors provided non-sterile) is a physical medical device (spinal fixation system component) and not an AI/ML-driven device or a diagnostic tool that would typically have acceptance criteria presented as sensitivity, specificity, or similar performance metrics derived from a study involving ground truth established by experts.

Therefore, I cannot populate the table or answer the specific questions about acceptance criteria and a study proving performance, as this type of information is not present in the provided text for this particular device submission. The submission relies on demonstrating substantial equivalence to previously cleared predicate devices due to no change in design or fundamental technology, other than the sterilization status of the component.

The provided text is a 510(k) summary for the Medtronic CD Horizon™ Spinal System, Medtronic Navigated Reusable Instruments, and Medtronic Reusable Instruments Compatible with the IPC® POWEREASE® System. It describes the devices, their indications for use, and a comparison to predicate devices, focusing on the substantial equivalence based on mechanical testing and software verification.

However, the document does not contain information typically found in a study proving an AI/ML device meets acceptance criteria. Specifically, it does not describe:

• Acceptance criteria for an AI/ML model's performance (e.g., sensitivity, specificity, AUC).
• A test set (sample size, provenance).
• Expert consensus for ground truth.
• Adjudication methods.
• Multi-reader multi-case (MRMC) studies or effect sizes for AI assistance.
• Standalone AI performance.
• Training set details.

The performance data mentioned is for mechanical testing of the spinal system and software verification of the instruments, not for an AI/ML algorithm that interprets medical images or other data to provide diagnostic or prognostic information.

Therefore, I cannot provide a table of acceptance criteria and reported device performance related to an AI/ML device, nor answer most of the specific questions about such a study, because the provided text does not describe an AI/ML device or its associated performance study.

The "Performance Data" section states: "For the subject instruments compatible with STEALTHSTATION® System and IPC™ POWEREASE™ Systems, software verification testing and activities were performed that demonstrated that the subject instruments performed as intended." This refers to verifying the proper functioning of the software-controlled instruments, not the performance of an AI algorithm making medical diagnoses or predictions.

The provided text describes the CD Horizon™ Spinal System and details its various components and indications for use. It also mentions non-clinical and clinical performance data used to demonstrate substantial equivalence to predicate devices, but it does not provide specific acceptance criteria or reported device performance in a numerical format.

However, based on the information provided, here's a breakdown of the requested information, focusing on what can be inferred or explicitly stated:

1. Table of Acceptance Criteria and Reported Device Performance

This information is not provided in the document. The document states that "mechanical testing was performed on the subject and predicate devices in accordance with ASTM F1717, Standard test Methods for Spinal Implant Constructs in a Vertebrectomy Model and ASTM F1798, Standard Guide for Evaluating the Static and Fatigue Properties of Interconnection Mechanisms and Sub-assemblies Used in Spinal Arthrodesis Implants." It also mentions "Biomechanical cadaver testing was also performed." However, the specific acceptance criteria (e.g., minimum load to failure, fatigue cycles survived) and the reported device performance metrics against those criteria are not detailed.

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

From the provided text:

• Clinical Performance Study: "A retrospective study was conducted..."
• Sample Size: The sample size for the retrospective clinical study is not explicitly stated in the provided text.
• Data Provenance: The text states, "A retrospective study was conducted and demonstrated that CD Horizon™ Spinal System PEEK Rod constructs are substantially equivalent when used to provide supplemental fixation in interbody fusion procedures for the treatment of DDD." The country of origin is not specified, but given the US FDA submission context, it is likely that the data pertains to a US patient population or has relevance to the US market. The study is explicitly stated as retrospective.

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

This information is not provided in the document. For a retrospective clinical study, ground truth for diagnoses like DDD, spondylolisthesis, etc., would typically be established based on existing patient medical records, imaging reports, and potentially physician-recorded outcomes. The number and qualifications of experts involved in the initial diagnosis or in reviewing the retrospective data for the study are not mentioned.

4. Adjudication Method

This information is not provided in the document. It's likely that for a retrospective study using existing medical records, the "ground truth" was established by the original treating physicians or based on the documented diagnostic criteria in the medical charts, rather than a separate adjudication process for the study.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done, and Effect Size

This information is not provided in the document. The study mentioned is a retrospective clinical study for the device itself, not a comparative effectiveness study involving human readers with and without AI assistance.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) was Done

This question is not applicable to the described device. The CD Horizon™ Spinal System is a medical implant (a hardware device), not an algorithm or AI system. Therefore, standalone algorithm performance is not relevant.

7. The Type of Ground Truth Used

Based on the description of the retrospective clinical study:

• The ground truth would likely be based on clinical diagnoses (e.g., degenerative disc disease, spondylolisthesis, trauma, spinal stenosis, curvatures, tumor, pseudarthrosis, failed previous fusion, progressive spinal deformities, etc.) as recorded in patient medical records.
• It would also involve radiographic studies for DDD, and potentially surgical outcomes (e.g., fusion success, complication rates) and patient-reported outcomes to demonstrate the clinical effectiveness of the device as supplemental fixation.
• For the non-clinical mechanical testing, the ground truth would be the physical properties and performance characteristics of the device measured against established ASTM standards.

8. The Sample Size for the Training Set

This question is not applicable to the described device. As the CD Horizon™ Spinal System is a medical implant, it does not involve a "training set" in the context of machine learning algorithms.

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

This question is not applicable to the described device, as there is no "training set" for a hardware medical implant.

This document describes the safety and performance testing for a medical device (CD HORIZON™ Spinal System) and does not involve AI/ML. Therefore, I cannot extract information related to AI/ML device performance, such as:

• Acceptance criteria and reported device performance for an AI/ML device
• Sample size and data provenance for an AI/ML test set
• Number and qualifications of experts for AI/ML ground truth
• Adjudication method for AI/ML
• MRMC comparative effectiveness study for AI/ML improvement
• Standalone AI/ML performance
• Type of ground truth for AI/ML
• Sample size and ground truth establishment for AI/ML training set

The document primarily focuses on demonstrating substantial equivalence to predicate devices through biocompatibility and mechanical testing, which are standard for traditional medical implants. The key takeaway from the performance data section is that non-clinical mechanical testing was not performed on the sterile implants because they are "identical to the predicate devices in terms of material, rod compatibility sizes, rod interconnection features, intended use and indications for use." The predicate devices were tested according to ASTM F1798 and F1717, and this is deemed sufficient for the new components.
