The IdentiTi and Transcend NanoTec Interbody Systems implant surfaces have been treated with a 20-40 nanometer thin hydroxyapatite (HA) surface treatment. The surface treatment presents nano-scale topography on the entirety of the implant surface, in addition to macro-/micro-scale topography existing from prior to treatment.

The purpose of this Traditional 510(k) is to receive clearance for expanded indications for use of the IdentiTi and Transcend Interbody Systems with bone void filler cleared by FDA for use in intervertebral body fusion to facilitate fusion, and to add a nanotechnology claim in alignment with FDA's Guidance for Industry: Considering Whether an FDA-Regulated Product Involves the Application of Nanotechnology.

The provided text describes the 510(k) premarket notification for the IdentiTi and Transcend Interbody Systems, which are intervertebral body fusion devices. This document focuses on demonstrating substantial equivalence to predicate devices rather than proving device safety and effectiveness through clinical studies with acceptance criteria in the typical sense of a novel device.

Therefore, many of the requested sections regarding acceptance criteria, sample sizes, expert ground truth, adjudication methods, MRMC studies, and details on training/test sets are not applicable in this context, as the submission relies on non-clinical performance data and comparison to already cleared predicate devices.

However, I can extract information related to the device's performance in non-clinical testing and the rationale for the nanotechnology claim.

1. Table of Acceptance Criteria and Reported Device Performance

Since this is a 510(k) submission for substantial equivalence based on non-clinical testing and nanotechnology claims, explicit "acceptance criteria" in the sense of clinical performance endpoints are not provided. Instead, the document mentions "in vitro evaluations" for the nanotechnology claim and adherence to ASTM standards for mechanical testing. The reported performance is that these tests were "performed and included" or "referenced in predicate 510(k) submissions to support clearance." For the nanotechnology claim, the "reported device performance" is the demonstrated statistically significantly increased proliferation, alkaline phosphatase activity, and mineralization.

2. Sample size used for the test set and the data provenance

• Nanotechnology Test Set: The document mentions testing on "human mesenchymal stem cells (hMSCs) and human osteoblasts (hOBs)." No specific sample size (number of cell cultures, replicates, etc.) is provided in the document.
• Mechanical Testing Test Set: Not specified in terms of number of devices tested; references to ASTM standards imply that standard testing protocols were followed.
• Data Provenance: The in vitro evaluations for the NanoTec surface treatment are implied to be prospective studies conducted by the submitter. For other tests, they were "performed and included" or "referenced in predicate 510(k) submissions," suggesting a mix of new testing and reliance on previously cleared data. Country of origin is not specified, but the submitter is Alphatec Spine, Inc. in Carlsbad, CA, USA.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. The non-clinical studies do not involve expert-established ground truth in the context of clinical image interpretation or diagnosis. The ground truth for cellular assays is laboratory-measured biological markers, and for mechanical tests, it's defined by the physical responses measured according to engineering standards.

4. Adjudication method for the test set

Not applicable. There is no human interpretation or adjudication involved in the reported non-clinical testing.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This submission is for an intervertebral body fusion system, not an AI/imaging device, therefore MRMC studies are not relevant.

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

Not applicable. This submission is for a medical implant, not an algorithm.

7. The type of ground truth used

• Nanotechnology Claim: Laboratory measurements of cellular proliferation, alkaline phosphatase activity, and mineralization in cell cultures are used as "ground truth" to assess osteogenic differentiation.
• Mechanical Testing: Physical measurements obtained according to established ASTM standards (e.g., force, displacement, gravimetric changes) serve as the ground truth.

8. The sample size for the training set

Not applicable. There is no machine learning PAI involved, so no training set is used.

9. How the ground truth for the training set was established

Not applicable. As there is no training set, this question is not relevant.

Here's an analysis of the provided text regarding acceptance criteria and supporting studies:

1. Table of Acceptance Criteria and Reported Device Performance

The provided document does not explicitly state specific acceptance criteria values (e.g., "device must withstand 1000N axial compression"). Instead, it lists the types of non-clinical tests performed, implying that the devices met the requirements of these standard tests. The reported "performance" is implicitly that the devices passed these tests.

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

The document does not specify the sample sizes used for each non-clinical test (e.g., number of interbody devices tested for axial compression). It refers to the tests generally.

Regarding data provenance, the tests are non-clinical (laboratory tests) and therefore do not involve patient data or data from specific countries of origin. The data is prospective as it was generated specifically for this submission.

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

This question is not applicable to this submission. The "ground truth" for the non-clinical performance tests is based on established engineering standards (ASTM) and the physical properties of the devices themselves, not on expert medical opinion or consensus.

4. Adjudication Method for the Test Set

This question is not applicable to this submission. Adjudication methods (like 2+1, 3+1) are typically used in clinical studies or studies involving human readers/interpreters, where discrepancies in interpretation need to be resolved. The non-clinical tests outlined here are objective measurements against predefined standards.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This question is not applicable to this submission. The device is an intervertebral body fusion system, a physical implant, not an AI diagnostic or assistance tool. Therefore, MRMC studies involving human readers or AI assistance are not relevant.

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

This question is not applicable to this submission. The device is a physical interbody fusion system, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

For the non-clinical performance tests, the "ground truth" is based on engineering standards and material science specifications. The tests are designed to assess the physical and mechanical properties of the interbody systems against recognized benchmarks for safety and effectiveness in their intended use.

8. The sample size for the training set

This question is not applicable to this submission. As the device is a physical implant and not an AI/ML algorithm, there is no "training set."

9. How the ground truth for the training set was established

This question is not applicable to this submission for the same reason as above (no training set).

The IdentiTi NanoTec Cervical Standalone Interbody System is intended to be used with the bone screw fixation provided and requires no additional fixation.

The IdentiTi and Transcend Interbody Systems are cervical and thoracolumbar intervertebral body fusion systems designed to be inserted through anterior and posterior approaches. The interbody spacers are manufactured surgical from PEEK (polyetheretherketone) Optima LT1 per ASTM F2026, tantalum per ASTM F560, titanium alloy (Ti-6Al-4V ELI), and commercially pure titanium (CPTi Grade 2) per ASTM F67. The interbody spacers are available in the following material options: (1) PEEK (polyetheretherketone) with tantalum and titanium alloy markers, or (2) commercially pure porous titanium (PTi), or (3) a combination of commercially pure porous titanium (CP Ti Grade 2) per ASTM F67 and titanium alloy (Ti-6Al-4V ELI) per ASTM F136.
The subject IdentiTi and Transcend Interbody Systems implants consist of various lengths, widths, heights and lordotic options to accommodate individual patient anatomy. To mitigate risk of expulsion, the interbody endplates feature teeth. All interbody spacers feature an internal graft aperture for placement of graft material to promote fusion through the cage. Additionally, the IdentiTi implants are offered with a microstructure due to the layering of material that forms the porous architecture. This porous geometry extends to the superior and inferior surfaces of the device for implant fixation.
The IdentiTi and Transcend NanoTec Interbody Systems implant surfaces have been treated with a 20-40 nanometer thin hydroxyapatite (HA) surface treatment. The surface treatment presents nano-scale topography on the entirety of the implant surface, in addition to macro-/micro-scale topography existing from prior to treatment.
The IdentiTi ALIF and Cervical Standalone Interbody Systems accept two or three bone screws/bolts that are made of titanium alloy (Ti-6Al-4V ELI) per ASTM F136 in varying lengths and diameters.

This document is an FDA 510(k) Premarket Notification for various interbody fusion devices. It establishes substantial equivalence to previously cleared predicate devices, arguing that the new devices do not raise new questions of safety or effectiveness. As such, it does not contain acceptance criteria or a study that proves the device meets acceptance criteria in the context of an AI/ML algorithm's performance.

Instead, the document focuses on the mechanical and material properties of the interbody fusion implants. The "Performance Data" section explicitly states "Not applicable; determination of substantial equivalence is not based on an assessment of clinical performance data." and refers to mechanical testing on the predicate devices and Bacterial Endotoxin Testing (BET) for the subject devices.

Therefore, I cannot provide the requested information for an AI/ML study from this document. The information requested (acceptance criteria, sample size for test/training sets, expert qualifications, etc.) would only be relevant if the device involved an AI/ML component whose performance needed to be evaluated against clinical metrics, which is not the case here.

To re-iterate, this document is a 510(k) submission for spinal implants, not for an AI/ML-driven medical device.

The IdentiTi™ ALIF Standalone Interbody System is indicated for spinal fusion procedures in skeletally mature patients. The IdentiTi ALIF Standalone Interbody System implants of ≤20° are a standalone system. The IdentiTi ALIF Standalone Interbody System implants of >20° must be used with supplemental spinal fixation systems cleared by the FDA for use in the lumbar spine in addition to the integrated screws.

The IdentiTi ALIF Standalone Interbody System is intended for use at one or two contiguous levels in the lumbar spine (L2-S1) for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis at the involved level(s). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The IdentiTi ALIF Standalone Interbody System is intended for use on patients who have had at least six months of non-operative treatment. It is intended for use with autograft comprised of cancellous and/or corticocancellous bone graft.

The provided text is a 510(k) summary for a medical device called the "IdentiTi™ ALIF Standalone Interbody System". This document outlines the device's indications for use, its technical specifications, and a comparison to predicate devices, along with performance data from non-clinical testing.

However, the request asks for information about acceptance criteria and a study that proves the device meets those criteria, specifically in the context of an AI/human-in-the-loop study. The provided document explicitly states that no clinical performance data was used for the determination of substantial equivalence ("Not applicable; determination of substantial equivalence is not based on an assessment of clinical performance data.").

Therefore, most of the requested information regarding acceptance criteria, study design, sample sizes for test and training sets, expert consensus, adjudication methods, MRMC studies, standalone algorithm performance, and ground truth establishment cannot be found in this document, as it pertains to a different type of medical device submission (an interbody fusion system, not an AI-powered diagnostic/assistive tool) and regulatory pathway (510(k) based on substantial equivalence through non-clinical data).

Here is a summary of what can be extracted from the document in relation to the prompt:

1. A table of acceptance criteria and the reported device performance:

• Acceptance Criteria (Implicitly based on substantial equivalence to predicate devices): The device is substantially equivalent in terms of:
  • Intended Use
  • Indications for Use
  • Design
  • Function
  • Technology
  • Performance (based on nonclinical testing)
• Reported Device Performance (from nonclinical testing):
  • ASTM F2077 static & dynamic axial compression, static & dynamic 0 compression-shear
  • ASTM F1877 - particulate analysis
  • ASTM F1714 gravimetric analysis
  • ASTM F2267 subsidence
  • Static push-out
  • Screw push-out
• Conclusion: The results "demonstrate that the proposed IdentiTi™ ALIF Standalone Interbody System is substantially equivalent to the predicate devices for nonclinical testing."

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

• Not applicable. This document describes non-clinical, mechanical testing of a physical implant device, not a study involving a "test set" of patient data for an AI algorithm.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Not applicable. Ground truth in the context of diagnostic performance or AI algorithms is not discussed. The "ground truth" for this device's performance is derived from standardized mechanical testing protocols.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

• Not applicable.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

• No MRMC study was done. This is not an AI device.

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

• Not applicable. This is not an AI device.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc):

• For the physical device's performance, the "ground truth" is adherence to established ASTM (American Society for Testing and Materials) standards for intervertebral body fusion devices. This is a form of engineering or mechanical testing standard, not clinical ground truth.

8. The sample size for the training set:

• Not applicable. There is no training set for an AI algorithm mentioned.

9. How the ground truth for the training set was established:

• Not applicable. There is no training set for an AI algorithm mentioned.

In summary, the provided document details the regulatory clearance of a physical medical implant device based on substantial equivalence established through non-clinical bench testing, not on the performance of an AI algorithm or clinical studies requiring human-in-the-loop assessments. Therefore, most of the questions relating to AI performance metrics are outside the scope of this specific document.
