The OptiMesh Multiplanar Expandable Interbody Fusion System is indicated for use as an adjunct to fusion in an intervertebral body fusion at one level in the lumbar spine from L2 to S1 in skeletally mature patients with degenerative disc disease (DDD) with up to Grade I spondylolisthesis at the involved level. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history, physical examination, and radios. Eligible patients shall have undergone six (6) months of conservative (non-operative) care. The OptiMesh device with compatible allograft, or a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion, is intended for use with supplemental posterior fixation systems intended for use in the lumbar spine.

AFT is intended for use as a bone void filler in the extremities, spine, intervertebral disc space, and pelvis for voids or gaps that are not intrinsic to the stability of the bony structure. AFT is indicated for use in the treatment of osseous defects caused by surgery or traumatic injury. When used in intervertebral body fusion procedures, AFT must be used on its own with an intervertebral body graff containment device cleared by FDA for use with a bone void filler.

The OptiMesh Multiplanar Expandable Interbody Fusion System is an intervertebral body graft containment device that is a non-rigid, implanted spinal device that is designed to contain bone graft within its internal cavity. The device is inserted into the intervertebral body space of the spine and is intended as an adjunct to intervertebral body fusion.

AFT Allograft Filler Tube is composed of human demineralized bone matrix, human nondemineralized bone, and sodium hyaluronate. All components of AFT are resorbable. AFT is aseptically processed and provided pre-loaded into a disposable delivery tube.

The provided text describes a 510(k) premarket notification for the "OptiMesh Multiplanar Expandable Interbody Fusion System" with the addition of "AFT Allograft Filler Tube" as a compatible allograft. It outlines the purpose of the submission, device descriptions, indications for use, technological characteristics, and non-clinical/clinical testing. However, the document does not provide specific acceptance criteria or detailed study results in the format requested.

The FDA 510(k) clearance process focuses on demonstrating "substantial equivalence" to a legally marketed predicate device, rather than proving a device meets specific, quantifiable acceptance criteria with a detailed study report. The non-clinical and clinical data presented here are used to support this claim of substantial equivalence.

Based on the provided text, I can infer some aspects and highlight what is not present:

Inferred Information:

• Acceptance Criteria (Implied): The implied acceptance criteria revolve around demonstrating that the OptiMesh device with AFT performs comparably to the predicate device and the reference devices in terms of mechanical performance and biological impact, without introducing new safety or effectiveness concerns. This means that:
  • Mechanical performance of OptiMesh + AFT should be "as intended" and comparable to the reference device and ISO 23089-2 data.
  • Biological impact of AFT should be comparable to the reference bone graft.
  • Biocompatibility, pyrogenicity/endotoxin, sterilization, packaging, and shelf-life should be acceptable and comparable.
  • The risk profile should not be altered, and new safety/effectiveness issues should not arise.
• Study Proving Acceptance Criteria: The study used to demonstrate this is primarily a critical engineering and clinical comparison to a bone graft used in a prospective, multi-center, non-randomized, FDA and IRB approved performance goal clinical investigation.

Information NOT present explicitly in the document:

• Specific quantifications of acceptance criteria.
• A table of acceptance criteria and reported device performance with numerical values.
• Sample sizes used for the test set (e.g., number of patients/data points in the clinical investigation for comparison).
• Data provenance (country of origin, retrospective/prospective for the comparison study). While it mentions a "prospective" clinical investigation for the reference bone graft, it doesn't specify if the comparison itself involved new prospective data or a retrospective analysis of the existing investigation's data.
• Number of experts used to establish ground truth or their qualifications.
• Adjudication method for the test set.
• MRMC comparative effectiveness study details (effect size, human reader improvement). This type of study is more common for diagnostic imaging AI than for interbody fusion systems.
• Standalone algorithm performance (algorithm only without human-in-the-loop). This is a physical device, so "standalone algorithm performance" is not applicable in the typical AI/software sense.
• Type of ground truth used (pathology, outcomes data, etc.) beyond "clinical data" and "performance goal clinical investigation."
• Sample size for the training set. There's no mention of a "training set" in the context of an AI/machine learning model. This submission is for a physical medical device.
• How the ground truth for the training set was established. (Not applicable for this type of device submission).

Given these limitations, here is the best possible answer based only on the provided text, heavily inferring the "acceptance criteria" based on the substantial equivalence claims:

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample size used for the test set and data provenance:
* Sample Size: Not specified in the given text.
* Data Provenance: The clinical data for comparison comes from a "prospective, multi-center, non-randomized, FDA and IRB approved performance goal clinical investigation" involving a reference bone graft. The country of origin is not specified but it's an FDA-approved study, implying it was likely conducted in the US or under FDA oversight for data acceptability.

3. Number of experts used to establish the ground truth for the test set and their qualifications:
* Not specified. The clinical investigation mentioned for comparison would have medical professionals involved, but the text does not detail the "ground truth" establishment process by experts in the context of this submission.

4. Adjudication method for the test set:
* Not specified.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and its effect size:
* No, an MRMC study is not mentioned. This type of study is typically for evaluating diagnostic imaging systems where human readers interpret medical images. This submission is for a physical interbody fusion system.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
* No, this concept is not applicable. The device is a physical medical implant, not an AI algorithm.

7. The type of ground truth used:
* The term "ground truth" is not explicitly used in the context of a dataset for algorithmic evaluation. However, for the clinical performance comparison, the "performance goal clinical investigation" likely established clinical outcomes (e.g., fusion rates, pain reduction, adverse events) as the de facto "truth" against which the subject device's performance (via comparison to a reference bone graft) was evaluated.

8. The sample size for the training set:
* Not applicable. This submission is for a physical medical device, not an AI/machine learning model that would require a training set.

9. How the ground truth for the training set was established:
* Not applicable, as there is no training set for an AI model.

The Duo implant is available in varying lengths and heights with three lordotic configurations and is provided sterile. The device is designed with a porous central cavity for graft containment, a rounded nose to aid implant insertion, and ridged teeth to resist migration.

This document is an FDA 510(k) clearance letter for a medical device called the "Duo™ Lumbar Interbody Fusion Device." It does not contain information about acceptance criteria or a study proving the device meets those criteria, as typically seen for AI/ML-based medical devices or diagnostics.

The document pertains to a physical intervertebral body fusion device and focuses on establishing its substantial equivalence to a previously cleared predicate device. The "Non-Clinical Testing" section mentions mechanical testing (static and dynamic axial compression, compression-shear, subsidence, and expulsion) conducted on the primary predicate device and "engineering analysis and verification testing (expulsion testing)" that supported this implant line extension. This suggests the testing was for the physical properties and performance of the implant, not about a software device meeting specific performance metrics based on data.

Therefore, I cannot provide the requested information regarding acceptance criteria and a study proving a device meets those criteria, as this document does not describe such a study or performance metrics relevant to AI/ML or diagnostic devices.

Acceptance Criteria and Device Performance (as demonstrated for this type of device):

The "acceptance criteria" for a 510(k) submission for a non-AI medical device like this are primarily demonstrating substantial equivalence to a legally marketed predicate device in terms of intended use, technological characteristics, and safety/effectiveness.

Detailed Study Information (largely N/A for this 510(k) submission):

1. Sample size used for the test set and the data provenance:

   • N/A. This clearance is for surgical instruments, not an AI model evaluated on a "test set" of patient data. The "testing" involved non-clinical design verification (e.g., instrument mating, performance confirmation) for the adapter. The exact sample size for these non-clinical tests is not specified in the summary, but it would typically involve a sufficient number of units to demonstrate design integrity, not a patient data sample.
   • Data Provenance: N/A. No patient data provenance specified as clinical data was not required.

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

   • N/A. Ground truth establishment by experts for a test set of patient data is not relevant to this submission, as no clinical study evaluating interpretation or diagnosis was performed.

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

   • N/A. Not applicable, as there was no test set requiring expert adjudication.

4. 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:

   • N/A. This device is a set of surgical instruments, not an AI or imaging diagnostic aid. No MRMC study was performed.

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

   • N/A. Not applicable, as this is not an algorithm.

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

   • N/A. No ground truth from patient data was established or used, as no clinical performance study was conducted. The "ground truth" for the non-clinical testing was based on design specifications and engineering requirements.

7. The sample size for the training set:

   • N/A. This device does not involve a "training set" in the context of machine learning or artificial intelligence.

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

   • N/A. Not applicable.

Summary of the "Study" (Non-Clinical Testing for Substantial Equivalence):

The "study" conducted for this 510(k) submission was a series of non-clinical design verification activities focused on the newly added Adapter to the Spineology Navigation Instruments.

• Purpose: To demonstrate that the design outputs of the subject Spineology Navigation Instruments (with the adapter) met the design input requirements and that the adapter did not introduce new issues of safety or effectiveness.
• Methods:
  • Assessment of instrument mating (how the adapter fits with other instruments).
  • Confirmation that the performance of Spineology Navigation Instruments is unaffected by the use of the Adapter.
  • A risk assessment to confirm no new safety or effectiveness issues.
• Conclusion: Spineology demonstrated substantial equivalence to the predicate device, confirming the same intended use and that any differences in technological characteristics (specifically the addition of the adapter) did not raise new issues of safety and effectiveness.
• Clinical Testing: Explicitly stated as "Clinical testing was not performed or required to establish the substantial equivalence of Spineology Navigation Instruments to the predicate device."

Here's what can be extracted from the provided text based on your request:

Acceptance Criteria and Reported Device Performance

The document does not explicitly state numerical acceptance criteria in the format of a typical clinical study. Instead, the "acceptance criteria" are implied by demonstrating substantial equivalence to a predicate device. The performance is assessed through non-clinical testing focused on compatibility and accuracy within the context of the Medtronic StealthStation System.

Study Details

1. Sample size used for the test set and the data provenance:

   • Test Set Sample Size: Not specified in terms of numerical count for instruments or specific test scenarios. The non-clinical testing generally refers to "Spineology Navigation Instruments."
   • Data Provenance: The "Non-Clinical Testing" section describes in-house design verification activities performed by Spineology Inc. No specific country of origin for data is mentioned, and the testing is described as internal verification rather than external data collection. The tests are retrospective in the sense that they are internal design verification activities.

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

   • This information is not applicable. The "ground truth" for non-clinical engineering tests (like instrument mating, registration, and accuracy) is typically established by engineering specifications, validated measurement systems, and comparison to known good standards or predicate device performance, not by clinical experts establishing ground truth in the way it's done for diagnostic AI. The document does not mention external experts or their qualifications for establishing ground truth in these non-clinical tests.

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

   • This information is not applicable. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies involving human interpretation or subjective assessments. The non-clinical tests described (instrument mating, registration, accuracy comparison) would involve objective measurements and comparisons against established metrics or predicate device performance, not clinical adjudication.

4. 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, an MRMC comparative effectiveness study was not done. This document pertains to the clearance of surgical navigation instruments, not an AI-assisted diagnostic or interpretative device. Therefore, there is no mention of human readers, AI assistance, or effect sizes in this context.

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

   • This information is not applicable. The device (Spineology Navigation Instruments) is a physical surgical instrument intended for use with the Medtronic StealthStation System and by a surgeon (human-in-the-loop). It is not an algorithm that operates in a standalone capacity.

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

   • For the non-clinical tests described, the "ground truth" would be based on:
     • Engineering Specifications: For instrument mating and registration, the "ground truth" is that the instruments must correctly connect and register according to pre-defined engineering standards for the Medtronic StealthStation System.
     • Predicate Device Performance: For accuracy, the "ground truth" is the established accuracy of the equivalent Medtronic Navigation Instruments, to which the new Spineology instruments were compared.
   • This is not clinical ground truth like pathology or outcomes data.

7. The sample size for the training set:

   • This information is not applicable. There is no mention of a "training set" because this device is a physical instrument, not an AI or machine learning model that requires training data.

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

   • This information is not applicable as there is no training set mentioned or implied for this device.

Since new performance testing was not conducted for this specific submission, there isn't a table of new acceptance criteria and device performance. The document states that the initial performance testing for the Rampart One device remains valid. That initial testing established conformance to the following standards:

Note: The specific quantitative performance metrics (e.g., specific load values, displacement limits) for "conformed" are not provided in this summary but would have been part of the original K163670 submission's testing report.

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

• For Performance Testing: The sample sizes used for the initial performance testing (referenced but not detailed here) are not specified in this document. These would have been documented in the original K163670 submission.
• For Clinical Data (Review): The document mentions a "review of published clinical data," which implies data collected retrospectively or prospectively from various studies. No specific sample size or data provenance (e.g., country of origin) is given for this review, as it refers to a compilation of existing literature rather than a new, specific clinical study associated with this submission.

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

This information is not applicable to this submission, as no new clinical test set was created or evaluated in a way that required an independent expert panel for ground truth establishment. The clinical evaluation relied on a review of existing published literature.

4. Adjudication Method for the Test Set

This information is not applicable, as no new clinical test set requiring adjudication was performed for this submission.

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

No MRMC comparative effectiveness study was done for this submission. The submission states that "clinical testing was not required or performed to support substantial equivalence."

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

This question is not applicable as the device is a physical medical implant, not an algorithm or AI software, and therefore "standalone performance" in that context does not apply.

7. Type of Ground Truth Used

• For Performance Testing: The ground truth for the engineering performance tests (e.g., compression, pullout) is the physical properties and mechanical behavior of the device under specified testing conditions, as measured against the limits set by the ASTM standards.
• For Clinical Data Review: The "ground truth" for the clinical evaluation was derived from published clinical outcomes related to similar stand-alone anterior lumbar intervertebral body fusion devices with integrated fixation. This essentially means the consensus findings and results reported in established medical literature.

8. Sample Size for the Training Set

This is not applicable as the device is a physical implant and does not involve a "training set" in the context of an algorithm or AI model.

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

This is not applicable as the device is a physical implant and does not involve a "training set" in the context of an algorithm or AI model.
