Intended Use

Mineral Collagen Composite Bioactive Moldable is intended for use as a bone void filler for voids or gaps, that are not intrinsic to the stability of the bony structure. The device is to be gently packed into bony voids or gaps of the skeletal system (i.e., the extremities, pelvis, and posterolateral spine). 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.

For spine applications, Mineral Collagen Composite Bioactive Moldable is combined with either autogenous bone marrow or autograft with saline and can also be used with autograft as a bone graft extender.

Device Description

Mineral Collagen Composite Bioactive Moldable Bone Graft Matrix is composed of anorganic bone mineral, bioactive glass, and type I collagen that can be molded to fit the bone defect. It is an osteoconductive, bioactive, porous implant that allows for bony ingrowth across the graft site. The bone graft matrix is slowly resorbed and replaced by new bone tissue during the natural healing process.

The anorganic bone mineral component of the bone graft matrix is a natural, porous bone graft material produced by removal of all organic components from bovine bone. The composition of the anorganic bone mineral meets ASTM F1581 standard specifications for composition of anorganic bone for surgical implants. The bioactive glass component of the device is made of 45S5 Bioactive Glass and meets ASTM F1538 standard specifications for glass and glass ceramics biomaterials for implantation. The purified type I collagen is derived from bovine Achilles tendon.

The product is available in various sizes and is provided sterile, non-pvrogenic, and for single use only.

AI/ML Overview

The provided text is a 510(k) summary for the Mineral Collagen Composite Bioactive Moldable device. This document describes a medical device seeking regulatory clearance, not an AI/ML device study. Therefore, most of the requested information regarding acceptance criteria, study design for AI/ML performance, ground truth establishment, expert adjudication, MRMC studies, and standalone algorithm performance does not apply to this document.

The document focuses on demonstrating substantial equivalence to legally marketed predicate devices, primarily through non-clinical testing (biocompatibility, sterilization, pyrogen, packaging, shelf life, and animal studies). Clinical studies were explicitly not required for this determination.

Here's an attempt to answer the questions based on the provided document, highlighting where the requested information is not applicable:


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

The document does not specify quantitative acceptance criteria in a table format for performance. Instead, it relies on demonstrating that the device performs substantially equivalently to its predicate and reference devices, particularly for the expanded indications for use.

Acceptance Criteria (Implied)Reported Device Performance (Summary)
BiocompatibilityDeemed Biocompatible (ISO 10993) - No new testing required, data from K182074 remains valid.
SterilitySterile, SAL 10-6 (Gamma irradiation, ISO11137) - No new testing required, data from K182074 remains valid.
PyrogenicityNon-pyrogenic - No new testing required, data from K182074 remains valid.
Packaging & Shelf LifeValidated - No new testing required, data from K182074 remains valid.
Bench TestingNot required for substantial equivalence, as technological characteristics remain the same.
Animal PerformancePerformance in a rabbit femoral condyle critical-sized defect model was "substantially equivalent to the reference device" (SIGNAFUSE bioactive bone graft) with regards to the expansion of indications for use.

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

  • Animal Study: The document mentions "a rabbit femoral condyle critical-sized defect model." It does not specify the number of rabbits or exact sample size used for this study.
  • Data Provenance: The studies mentioned (biocompatibility, sterilization, pyrogen, packaging, shelf life) were completed under the original submission (K182074). The animal study appears to be part of the current submission, likely conducted for the expanded indications. The country of origin and whether the data was retrospective or prospective is not specified, but animal studies are typically prospective.

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

This information is not applicable as this is not an AI/ML device requiring human expert annotation for ground truth. Ground truth for a bone void filler would typically be established through histological analysis of tissue regeneration in the animal model. The document does not specify who conducted such analyses or their qualifications.

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

Not applicable for this type of device and study.

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 is not an AI/ML device that assists human readers.

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.)

For the animal study, the "ground truth" for assessing device performance would primarily be based on pathology/histology of bone regeneration and integration within the rabbit femoral condyle defects, comparing the test device to the reference device. The document states "The results demonstrate performance substantially equivalent to the reference device with regards to the expansion of the indications for use," implying such an assessment was made.

8. The sample size for the training set

Not applicable. This device is not an AI/ML algorithm that requires a training set.

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

Not applicable.

§ 888.3045 Resorbable calcium salt bone void filler device.

(a)
Identification. A resorbable calcium salt bone void filler device is a resorbable implant intended to fill bony voids or gaps of the extremities, spine, and pelvis that are caused by trauma or surgery and are not intrinsic to the stability of the bony structure.(b)
Classification. Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Resorbable Calcium Salt Bone Void Filler Device; Guidance for Industry and FDA.” See § 888.1(e) of this chapter for the availability of this guidance.
