The UNiD™ Spine Analyzer is intended for assisting healthcare professionals in viewing and measuring images as well as planning orthopedic surgeries. The device allows surgeons and service providers to perform generic, as well as spine related measurements on images, and to plan surgical procedures. The device also includes tools for measuring anatomical components for placement of surgical implants. Clinical judgment and experience are required to properly use the software.

The UNiD™ Spine Analyzer is a web-based application developed to perform preoperative and postoperative patient image measurements and simulate preoperative planning steps for spine surgery. It aims to make measurements on a patient image, simulate a surgical strategy, draw patient-specific rods or choose from a pre-selection of standard implants. The UNiD™ Spine Analyzer allows the user to:

1. Measure radiological images using generic tools and "specialty" tools
2. Plan and simulate aspects of surgical procedures
3. Estimate the compensatory effects of the simulated surgical procedure on the patient's spine

The planning of surgical procedures is done by Medtronic as part of the service of pre-operative planning. The surgical plan may then be used to assist in designing patient-specific implants. Surgeons will have to validate the surgical plan before Medtronic manufactures any implant.

The UNiD™ Spine Analyzer interface is accessible in either standalone mode or connected mode.

Here's a breakdown of the acceptance criteria and the study proving the device meets them, based on the provided FDA 510(k) clearance letter for the UNiD™ Spine Analyzer:

Overview of Device and Study Focus:

The UNiD™ Spine Analyzer is a web-based application designed to assist healthcare professionals in viewing, measuring, and planning orthopedic spine surgeries. This 510(k) submission primarily focuses on the update to the AI-enabled degenerative predictive model (Degenerative Predictive model). The study aims to demonstrate that this new version is non-inferior to the previous version (predicate device).

1. Table of Acceptance Criteria and Reported Device Performance

The core of the performance evaluation for this AI-enabled software function is focused on demonstrating non-inferiority of the updated "Degenerative Predictive model" to the predicate version.

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

• Test Set Sample Size: 274 patient surgery cases.
• Data Provenance:
  • Country of Origin: US only.
  • Retrospective/Prospective: The document states "Preoperative and post operative images from 1050 patient surgery cases were collected." This implies existing data, making it a retrospective collection.

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

• Number of Experts: Not explicitly stated as "experts." Instead, the document mentions "highly trained Medtronic measurement technicians."
• Qualifications of Experts: "Highly trained Medtronic measurement technicians, operating within a quality-controlled environment." The specific professional background (e.g., radiologist, orthopedist) or years of experience are not provided. They were responsible for vetting image viability and performing measurements.

4. Adjudication Method for the Test Set

The document does not explicitly describe an adjudication method (like 2+1 or 3+1 for consensus). It states that "After the images were collected, they were then provided to and measured by highly trained Medtronic measurement technicians, operating within a quality-controlled environment." This suggests a single evaluation per case by these technicians, which then forms the basis for the ground truth. There's no mention of multiple technicians independently measuring and then adjudicating discrepancies.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

• No, a formal MRMC comparative effectiveness study involving human readers assisting with AI vs. without AI assistance was not mentioned or described in this document. The study specifically focused on the AI model's performance (algorithm only) compared to its previous version, not the impact on human reader performance.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

• Yes, a standalone (algorithm only) performance study was done. The entire "AI-enabled device software functions (AI-DSF)" section describes the evaluation of the new Degenerative Predictive model's output against the ground truth, comparing its performance (MAEs) directly to the predicate AI model. This evaluates the algorithm itself.

7. The Type of Ground Truth Used

• Derived from Measured Images by Technicians: "Ground truth was derived from the measured images." These measurements were performed by the "highly trained Medtronic measurement technicians." This is a form of expert consensus/review, albeit by technicians rather than clinicians, and described as measurements on images. It is not pathology or outcomes data.

8. The Sample Size for the Training Set

• Training Set Sample Size: 776 patient surgery cases.

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

• The document implies the ground truth for the training set was established in the same manner as the test set: through measurements performed by "highly trained Medtronic measurement technicians." The statement "Ground truth was derived from the measured images" applies to the overall data collection process before splitting into training and testing sets.

The LigaPASS™ system is an implant for use in orthopaedic surgery. The system is intended to provide temporary stabilization as a bone anchor during the development of solid bony fusion and id in the repair of bone fractures. The indications for use are as follows:

· Spinal trauma surgery, used in sublaminar or facet wiring techniques;

· Spinal reconstructive surgery, incorporated into constructs for the purpose of correction of spinal deformities such as idiopathic and neuromuscular scoliosis in patients 8 years of age and older, adults scoliosis and kyphosis;

· Spine degenerative surgery as an adjunct to spinal fusions.

· Intended for use with a posterior spinal instrumentation construct when ligamentation is needed.

The LigaPASS™ system may also be used in conjunction with other medical implants made of titanium or cobalt-chrome alloy whenever "wiring" may help secure the attachment of other implants.

The purpose of this submission is to expand the indications of the LigaPASS™ system to include the use with a posterior spinal instrumentation construct when ligament augmentation is needed.

The LigaPASS™ 2.0 Ligament Augmentation System provides surgeons the ability to mimic anatomical muscle and ligament functionality and stabilization between vertebrae that are collapsed during surgery before fusion. The LigaPASS™ 2.0 Ligament Augmentation System is designed to restore balance and stability as a complement to a posterior thoracolumbar fixation system. Ergonomic instrumentation provides smooth assembly with self-stabilizing tensioners and torque-limiting locking tools. The LigaPASS™ 2.0 Ligament Augmentation System consists of a polyester (PET) band and titanium alloy medial open connector with 2 set screws.

LigaPASS™ bands allow the surgeon to create a posterior vertebra anchorage without theuse of a pedicle screw or hook. Instead of a pedicle screw or hook, the LigaPASS™ bands are laced around the vertebra independently of the vertebra anatomy and then connected to a LigaPASSTM connector to make the rod-bone connection.

The LigaPASS™ 2.0 bands are comprised of a PET braid and pure titanium (T40) malleable leads at the ends of the bands. The malleable tips help the surgeon to lace the band around the vertebra. They can be bent by the surgeon to make it pass under and through the vertebral body easier.

The LigaPASS™ connectors allow surgeons to attach a rod to a vertebral body without the use of the pedicle. Instead of a pedicle screw, the LigaPASS™ connector use a facet band to make the rod-bone connection. The connectors are comprised of a connector body, a rod set screw, a locking set screw for the band and a polyester band. The body of these connectors is manufactured from titanium allov (Ti-6Al-4V). The part is compatible with any rods made of titanium or cobalt chromium alloys between diameters 5.5 mm and 6.0 mm.

The provided text is a 510(k) premarket notification decision letter and summary for the LigaPASS™ 2.0 Ligament Augmentation System. It does not contain information about acceptance criteria or a study proving that an AI/Software as a Medical Device (SaMD) meets acceptance criteria.

The document pertains to a physical medical device (ligament augmentation system) used in orthopedic surgery, not a diagnostic or AI-powered device. The "Performance Testing Summary" explicitly states:

"No additional bench or animal testing was completed for the purpose of this 510(k) submission. The non-clinical performance of the LigaPASS™ 2.0 Medial System has been validated through a series of 510(k) submissions (K172021, K173506). Clinical data published in the literature were provided to support the use of ligament augmentation with the LigaPASS™ system in adult spinal deformity surgery."

Therefore, I cannot extract the requested information regarding AI device acceptance criteria and study details from this document.

The primary purpose of this submission is to add UNiD™ Patient Specific Rods (new diameter 4.75mm) and to change the proprietary Trade Name from "PASS LP™ Patient Specific Rods" to "UNiD™ Patient Specific Rods."

The testing conducted is for mechanical equivalence, not clinical performance or diagnostic accuracy. Therefore, concepts like sensitivity, specificity, accuracy, and reader studies (MRMC, standalone algorithm performance) are not applicable to this type of device submission. The acceptance criteria and "performance" here refer to mechanical strength and durability.

Here's a breakdown of the information requested:

1. Table of Acceptance Criteria and Reported Device Performance

Given the nature of the device (implantable spinal system), the acceptance criteria are based on mechanical properties as per a recognized standard. The document does not provide specific numerical acceptance criteria (e.g., minimum load values) but rather states that testing was conducted in accordance with a standard and demonstrated mechanical equivalence.

2. Sample Size for the Test Set and Data Provenance

• Sample Size for Test Set: Not explicitly stated. Mechanical testing typically involves a sufficient number of samples (e.g., typically n=5 or n=6 per test condition for medical device mechanical testing) to provide statistically significant results according to the chosen standard (ASTM F1717-18).
• Data Provenance: The testing was conducted by Medicrea (Medtronic). It's scientific/engineering test data, not patient data, so 'country of origin' of data or 'retrospective/prospective' doesn't apply in the common clinical sense. The manufacturer is based in France.

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

• Number of Experts: Not applicable. Ground truth for mechanical testing is established by recognized engineering standards (ASTM F1717-18) and measured physical properties, not expert consensus.
• Qualifications of Experts: N/A.

4. Adjudication Method for the Test Set

• 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.

The provided text describes the UNiD™ Spine Analyzer, a medical image management and processing system, and its submission for FDA 510(k) clearance. Here's information extracted regarding acceptance criteria and the study that proves the device meets them:

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

The document does not explicitly present a table of acceptance criteria with corresponding performance metrics in a quantitative manner for the "Predictive Models" (Degenerative Predictive Model, Adult Predictive Model, Pediatric Predictive Model). Instead, it states that these additions are "similar to the display of reference and normative data, and does not raise new questions of safety and effectiveness when considered with existing methods of managing spinal compensation."

For the software as a whole, the acceptance criteria are described indirectly through the validation activities:

• Comprehension of the Health Care professional with the UNiD Spine Analyzer,
• Appropriate human factors related to the UNiD Spine Analyzer, and
• Ease of use of the UNiD Spine Analyzer. |

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

• Predictive Models: The predictive models (Degenerative, Adult, and Pediatric) were "trained with retrospective longitudinal patient datasets." No specific sample size for these datasets or their provenance (country of origin) is provided.
• Software Validation/Verification: The document does not specify a separate "test set" sample size for the software validation activities beyond stating that "the software was tested against the established Software Design Specifications."
• Usability Study: No specific sample size (number of users) is mentioned for the usability study.

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

This information is not provided in the document. The document refers to the predictive models being "trained with retrospective longitudinal patient datasets" but does not detail how the ground truth for these training sets or any potential test sets was established, nor does it mention the involvement or qualifications of experts in this process for external validation. The clinical judgment of healthcare professionals is explicitly stated as required for proper software use, but not for ground truth establishment.

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

This information is not provided in the document.

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:

A multi-reader, multi-case (MRMC) comparative effectiveness study was not conducted or reported for this submission. The document explicitly states: "There was no human clinical testing required to support the medical device as the indications for use is identical to the predicate device." The new features (predictive models) are presented as an "additional tool" similar to "display of reference and normative data" and are not claimed to improve human reader performance with a measurable effect size.

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

The document mentions "Addition of the display of a Predicted Value derived from a static machine-learning based model" when the user views simulated quantitative radiographic parameters. This implies a standalone algorithmic prediction output. However, there are no specific performance metrics or a standalone study reported for the algorithm itself (e.g., accuracy of predictions against ground truth without human intervention).

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

For the predictive models, the ground truth for the training data was derived from "retrospective longitudinal patient datasets." The specific nature of this ground truth (e.g., direct surgical measurements, post-operative imaging, clinical outcomes) is not explicitly stated, beyond it being used to train models for "predicted spinal compensation."

8. The sample size for the training set:

The document states that the predictive models were "trained with retrospective longitudinal patient datasets" but does not specify the sample size for these training sets.

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

The document states the predictive models were trained using "retrospective longitudinal patient datasets."

The C-CURVE® Device is an anterior cervical intervertebral body fusion device indicated for use in skeletally mature patients with degenerative disc disease (DDD) (defined as pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies) at one disc level from C2 to T1. Patients should have received 6 weeks of non-operative treatment prior to treatment with the device is indicated to be used with autograft bone and/or allograft bone comprised of cancellous and/or corticocancellous bone and/or demineralized allograft bone with bone marrow aspirate. The device is a stand-alone system when used C-Curve screws and when used without the integrated screws it requires additional supplemental fixation cleared for the cervical spine.

MEDICREA® INTERNATIONAL S.A. C-CURVE® is composed of a cervical cage range stabilized by C-CURVE® screws. The titanium cage is composed of two pre-assembled components (the cage body and an expansion screw) that enable its expansion and adaptation of its lordotic angle. The cages are delivered individually and the screws are provided separately by two. The cages are available in different footprints and heights. These implants are designed to be inserted between two adjacent cervical vertebrae after removal of the disc. C-CURVE® is implanted by anterior approach. It is important to refer to the surgical technique and to the Instructions For Use (see paragraph «IMPLANT INSERTION», especially to use the two screws to stabilize the cage). C-CURVE® can be considered as a stand-alone cage if the two screws are used to stabilize the cage. If it is not the case, an additional fixation system must be added. Titanium cages & screws are manufactured in titanium alloy Ti-6Al-4V ELI conforming to ISO 5832-3 specifications and ASTM F136 specifications. Under no circumstances are the implants reusable.

The provided document is a 510(k) premarket notification for the C-CURVE device, an anterior cervical intervertebral body fusion device. It primarily focuses on demonstrating substantial equivalence to predicate devices based on intended use, material, and mechanical performance. The document does not contain acceptance criteria for device performance based on a clinical study of diagnostic accuracy or a human factors study related to AI/human interaction.

Therefore, I cannot provide information for many of the requested points, as they pertain to clinical or diagnostic performance studies that are not detailed in this regulatory submission.

However, I can extract information related to the non-clinical testing performed:

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

The document does not explicitly state quantitative acceptance criteria for the mechanical tests, but it does state that the tests "indicate that the product is mechanically equivalent to its predicates."

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

This document details non-clinical mechanical bench testing. The "test set" would refer to the number of devices tested. The document does not specify the exact number of C-CURVE devices or predicate devices used for these tests. Data provenance is not applicable as this is bench testing, not patient data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This is not applicable as the document describes non-clinical mechanical testing, not a study requiring expert readers to establish ground truth.

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

This is not applicable as the document describes non-clinical mechanical 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

No such study was conducted or reported in this document. This typically applies to AI/software as a medical device (SaMD) used for diagnostic purposes.

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

This is not applicable as the document describes a physical intervertebral body fusion device and its mechanical performance, not a standalone algorithm.

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

For the mechanical testing, the "ground truth" would be the established industry standards (ASTM F2077, ASTM F2267) and the mechanical performance of the legally marketed predicate devices.

8. The sample size for the training set

This is not applicable as the C-CURVE device is a physical implant, not an AI/ML algorithm that requires a training set.

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

This is not applicable.

I apologize, but the provided text does not contain the information needed to answer your request. The document is an FDA 510(k) clearance letter and summary for a medical device (UNiD® IB3D ALIF), an intervertebral body fusion device.

It focuses on regulatory clearance based on substantial equivalence to predicate devices, rather than an AI/ML-driven device's performance study against specific acceptance criteria.

The text does not include:

• A table of acceptance criteria and reported device performance for an AI/ML device.
• Details about sample sizes used for test sets or data provenance.
• Information on experts used to establish ground truth.
• Adjudication methods.
• Results of a multi-reader multi-case (MRMC) comparative effectiveness study.
• Standalone algorithm performance.
• Types of ground truth used (e.g., pathology, outcomes data).
• Sample size for a training set.
• How ground truth for a training set was established.

The document discusses mechanical testing (Finite Element Analysis - FEA) of the physical implant, concluding that no new worst-case implant was created, thus no additional physical testing was deemed necessary. This is typical for a physical medical device clearance, not an AI/ML software.

Therefore, I cannot fulfill your request based on the provided input.

It is intended for insertion between two adjacent vertebrae by an anterior approach. The MEDICREA® INTERNATIONAL implant is manufactured from titanium alloy Ti-6Al-4V ELI following standards ASTM F3001, a radio opaque material. As any orthopaedic implant, the lumbar interbody device must not be reused. The surgeon should strictly follow the recommendations provided in the surgical technique.

The provided text is a 510(k) premarket notification for a medical device called "IB3D ALIF," an intervertebral body fusion device. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting a de novo clinical trial with defined acceptance criteria and human reader studies (MRMC studies).

Therefore, the document does not contain the information requested regarding acceptance criteria related to AI/algorithm performance, and other specifics typically found in studies proving a device meets such criteria (e.g., sample size for test sets, data provenance, number of experts, adjudication methods, MRMC studies, standalone algorithm performance, ground truth types, training set details).

The requested information is not available in the provided text because this is a 510(k) submission for a physical implant (an intervertebral body fusion device), not a software or AI-driven diagnostic device.

Here's an explanation of why the requested information is absent and what is typically provided in a 510(k) for a physical device:

• Acceptance Criteria and Device Performance (Table): Not applicable in the context of AI software. For this device, "performance" relates to mechanical strength, biocompatibility, and intended function as an intervertebral body fusion device, which are tested against standards like ASTM F2077 and F2267. The document states "no new worse-case implant was created" by FEA, and expulsion testing was conducted, but specific pass/fail criteria or detailed results are not explicitly listed in this summary.
• Sample Size, Data Provenance, Experts, Adjudication, MRMC, Standalone Performance, Ground Truth Type (for test set), Training Set Details: These questions are specifically relevant to the evaluation of AI or imaging diagnostic software. The IB3D ALIF is a physical implant. Its evaluation for 510(k) clearance primarily involves:
  • Mechanical Testing: Such as finite element analysis (FEA) and expulsion testing to ensure the device can withstand forces and maintain placement.
  • Biocompatibility Testing: Ensuring the materials are safe for implantation in the human body.
  • Materials Comparability: Demonstrating the materials are the same as previously cleared predicate devices.
  • Indications for Use Comparability: Showing the device is intended for the same patient population and conditions as predicate devices.
  • Sterilization Validation: Ensuring the device can be sterilized effectively.

In summary, the provided document relates to a physical medical device (an implant) and not an AI or software-based diagnostic tool. As such, the concept of "acceptance criteria" and "studies" as understood for AI/software in the prompt are not relevant to this 510(k) submission.
