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.

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.

Ask a specific question about this device

The IdentiTi™ Cervical Standalone Interbody System is a stand-alone anterior cervical interbody fusion system intended for use as an adjunct to fusion at one or two contiguous levels (C2-T1) in skeletally mature patients of degenerative disc disease (defined as discogenic neck pain with degeneration of the disc confirmed by history and radiographic studies). These patients should have received at least six weeks of non-operative treatment with the device. The IdentiTi Cervical Standalone Interbody System is to be used with autograft bone graft and/or allogeneic bone graft composed of cancellous and/or cortico-cancellous bone and implanted via an open, anterior approach. The IdentiTi Cervical Standalone Interbody System is intended to be used with the bone screw fixation provided and requires no additional fixation.

The IdentiTill Cervical (IdentiTi-C) Standalone Interbody System is an integrated intervertebral body fusion device for use in Anterior Cervical Discectomy and Fusion (ACDF) Procedures. The IdentiTi Cervical Standalone Interbody System consists of integrated interbody spacers and bone screws in multiple configurations to accommodate individual patient anatomy.

The IdentiTi Cervical Standalone Interbody System interbody spacers are manufactured from a combination of commercially pure porous titanium (CP Ti Grade 2) per ASTM F67 and titanium alloy (Ti-6A1-4V ELI) per ASTM F136. The IdentiTi Cervical Standalone Interbody System interbody spacers are provided in multiple footprints with varying lengths, widths, heights, and angles of lordosis to accommodate individual patient anatomy.

The anterior face of the interbody spacer includes two screw holes to accept two bone screws that are made of titanium alloy (Ti-6Al-4V ELI) per ASTM F136 in varying lengths and diameters. All interbody spacers feature an internal graft aperture for placement of graft material to promote fusion through the cage.

The subject interbody spacers are provided individually packed and sterile. The subject bone screws are provided non-sterile to be cleaned and steam-sterilized by the end user.

The system provides reusable instruments that support varying surgical techniques, common with the ACDF approach, and are made of stainless steel and other materials. They are provided non-sterile to be cleaned and sterilized by the end user.

The provided document is a 510(k) summary for a medical device (IdentiTi™ Cervical Standalone Interbody System). It describes the device, its intended use, and a comparison to predicate devices, but it does not contain information about acceptance criteria or a study proving that a device meets acceptance criteria related to AI or diagnostic performance.

The "PERFORMANCE DATA" section explicitly states: "Not applicable; determination of substantial equivalence is not based on an assessment of clinical performance data." This indicates that no clinical studies were performed to assess the performance of this specific interbody system against clinical acceptance criteria. The performance data listed (ASTM F2077, F1877, F1714, F2267, F-04.25.02.02, and Static screw push-out) are non-clinical (mechanical and material) tests for substantial equivalence, not clinical performance studies with acceptance criteria as requested in the prompt.

Therefore, I cannot provide the requested information based on the given text.
