Mastergraft™ Matrix EXT is to be combined with autogenous bone marrow and is indicated for bony voids or gaps not intrinsic to the stability of the bony structure and can be used as a bone graft extender. The device is to be gently packed into bony voids or gaps of the skeletal system (i.e., the posterolateral spine, intervertebral disc space, pelvis, ilium, and/or extremities). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The device resorbs and is replaced with bone during the healing process. When used in intervertebral body fusion procedures, Mastergraft™ Matrix EXT must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler.

The provided text is a 510(k) Premarket Notification from the FDA, which focuses on demonstrating substantial equivalence of a new medical device to existing predicate devices. It does not contain information about acceptance criteria or a study that proves the device meets specific performance metrics in the context of an AI/ML medical device.

The document discusses bone void filler devices (Mastergraft™ family) and their indications for use, stating that the current submission expands their use to include intervertebral disc space. The core of the notification is to establish that these devices are substantially equivalent to previously cleared devices. This is a regulatory pathway for medical devices that does not typically involve the kind of detailed performance studies with acceptance criteria, test sets, ground truth establishment, or clinical outcome measures that would be expected for a novel AI/ML diagnostic or prognostic tool.

Therefore, I cannot fulfill your request using the provided text because it does not describe:

1. Acceptance criteria for device performance (in the context of an AI/ML device).
2. A study proving the device meets acceptance criteria. The document references prior clearances and robust analysis from previous studies, but it doesn't detail a new study design, methodology, or results related to specific performance metrics for the current submission.
3. Details about sample sizes for test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, or training set details. These are all concepts relevant to the validation of AI/ML models, which are not discussed in this medical device submission.

The "Performance" section explicitly states: "The subject devices have been previously cleared under K141824, K082166, K071813, and K082918, which serve as Reference Devices. These submissions are leveraged to support the device's sterility, shelf-life, endotoxin, pyrogenicity, biocompatibility, and characterizations/bench performance as recommended in FDA's Class II Special Controls Guidance Document for Resorbable Calcium Salt Bone Void Filler Devices. The device's performance in intervertebral spine was supported by a robust analysis of bone grafting materials in the prior posterolateral spine fusion studies." This indicates reliance on previous data and general guidelines, not a new, specific performance study with the requested AI/ML validation metrics.

This FDA 510(k) summary for Medtronic's MASTERGRAFT® Matrix EXT bone void filler does not contain information about acceptance criteria and a study proving a device meets those criteria in the context of an AI/ML powered medical device.

Instead, this document is a Traditional 510(k) application focused on demonstrating substantial equivalence to previously cleared predicate devices. The primary purpose of this specific submission is the addition of a new contraindication to the Instructions for Use (IFU) for the MASTERGRAFT® Matrix EXT.

Therefore, many of the requested points regarding AI/ML device testing are not applicable to this document. The document describes a traditional medical device (bioresorbable collagen and calcium phosphate ceramic) and its non-clinical testing for substantial equivalence, not an AI/ML algorithm's performance.

Here's an analysis based on the provided text, highlighting what's available and what's not:

1. Table of acceptance criteria and the reported device performance

• Not Applicable. This document does not describe specific acceptance criteria in terms of performance metrics (e.g., sensitivity, specificity, or image analysis accuracy) for an AI/ML device. The "performance" mentioned refers to the general function and characteristics of the bone void filler, which are deemed "Identical" to the predicate devices.

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

• Not Applicable. No test set in the context of evaluating an AI/ML algorithm's performance is mentioned. The non-clinical testing refers to tests conducted on the physical device, not on data for algorithm evaluation.

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)

• Not Applicable. Ground truth, in the AI/ML sense, is not established or discussed in this document.

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

• Not Applicable. Adjudication methods for test sets are not relevant to this type of device submission.

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. No MRMC study or AI assistance is mentioned.

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

• Not Applicable. This is not an AI/ML algorithm.

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

• Not Applicable. Ground truth in this context is not defined as there is no algorithm being evaluated against such a benchmark. The "ground truth" for this device would be its physical and chemical properties and its biological interaction with bone, evaluated through non-clinical (e.g., biocompatibility, dissolution rate) and potentially clinical studies (which are referenced as already having occurred for the predicate).

8. The sample size for the training set

• Not Applicable. No training set for an AI/ML algorithm is mentioned.

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

• Not Applicable.
