InterCollagen® Guide is a resorbable collagen membrane, derived from porcine pericardium. InterCollagen® Guide is intended for periodontal and/or dental surgical procedures as a barrier membrane restricting the entry of rapidly proliferating non-osteogenic cells within the bone defect while allowing the ingrowth of slow-growing bone forming cells. The membrane is a bioresorbable barrier which eventually is remodeled and/or incorporated by the host tissue. InterCollagen® Guide is substantially resorbed within 15 weeks after implantation. It is adaptable and easy to handle. It can be trimmed to the desired size and conforms easily when hydrated. The product is terminally sterilized via gamma irradiation.
This FDA 510(k) summary describes the InterCollagen® Guide, a resorbable collagen membrane. The submission seeks to prove substantial equivalence to a predicate device, the Straumann Jason Membrane, rather than demonstrate strict acceptance criteria and performance against those criteria. Therefore, the response will be structured to extract relevant performance claims and the study details provided, even if they don't explicitly fit a "table of acceptance criteria" format with numerical targets.
1. Table of Acceptance Criteria and Reported Device Performance
As this is a 510(k) submission seeking substantial equivalence, explicit numerical "acceptance criteria" with defined thresholds are not typically presented in the same way as a de novo or PMA submission. Instead, the focus is on demonstrating similar performance to a legally marketed predicate device. The following table summarizes the key performance aspects that were evaluated and the results presented, which essentially serve as the "reported device performance" against the implicitly accepted standard of the predicate device's performance.
| Performance Aspect | Acceptance Standard (Implicitly based on Predicate Device) | Reported Device Performance (InterCollagen® Guide) |
|---|---|---|
| Biocompatibility | Meets ISO 10993 requirements for medical devices. | Non-mutagenic (Mouse Lymphoma, Ames Test) |
| (General) | Non-sensitizer (Kligman Maximization) | |
| Non-irritant (Intracutaneous irritation) | ||
| Non-cytotoxic (Cytotoxicity L929 Neutral Red uptake) | ||
| Non-toxic (Acute Systemic Toxicity, 90-day Subchronic Toxicity) | ||
| Non-pyrogenic (Pyrogenicity) | ||
| Minimum tissue reaction at 2, 11, and 15 weeks of implantation; no adverse tissue reaction to the host (Local effects after Implantation) | ||
| In Vivo Performance | Performance substantially equivalent to the predicate device (Jason membrane) in a canine model, with similar histological, histomorphometric, and micro-CT outcomes. | Performed in a manner substantially equivalent to the cleared predicate device across pathology, histology, histomorphology, and micro-CT endpoints. |
| Resorption Time | Substantially resorbed by 12 weeks (Predicate device: Straumann Jason Membrane) | Substantially resorbed by 15 weeks |
| Sterility Assurance | Sterility Assurance Level (SAL) of 10^-6 (Predicate device also achieves this) | Achieves a Sterility Assurance Level of 10^-6 (via Irradiation) |
| Viral Inactivation | Meets ISO 22442-3 | Viral inactivation studies performed in accordance with ISO 22442-3 to ensure viral safety. |
| Pyrogenicity (Batch) | Non-pyrogenic (release test) | Each batch tested for endotoxin (LAL test, USP <85>, USP <161>) as finished product release test. |
| Shelf Life/Stability | Performance testing of packaging system; Selection, qualification, and validation of packaging. | Product and packaging stability determined using real-time aging data; Packaging tested per ASTM D4169, ISO 11607. |
2. Sample size used for the test set and the data provenance
The primary "test set" for performance evaluation was the canine two-wall intrabony defect model.
- Sample Size: Not explicitly stated in terms of the number of animals or defects. The document mentions "End points for pathology, histology, histomorphology and micro-CT were taken after 2, 6, and 13 weeks," implying a longitudinal study.
- Data Provenance: Conducted as an animal study (canine model). The country of origin is not specified in the provided text. The study design was a comparison between the test article (InterCollagen® Guide), a predicate device (Jason membrane), and an empty control. This is a prospective study design for evaluating the device's performance post-implantation.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
The document does not explicitly state the number or qualifications of experts used to establish ground truth for the animal study. Histology, histomorphology, and pathology evaluations are typically conducted by trained veterinary pathologists or researchers specialized in bone regeneration, but specific details are not provided.
4. Adjudication method for the test set
The document does not specify any adjudication method for establishing ground truth in the animal study. Evaluations of pathology, histology, histomorphology, and micro-CT are usually performed by experts, but whether independent reviews or consensus methods were used is not mentioned.
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 performed. This device is a resorbable collagen membrane for guided bone and tissue regeneration, not an AI-assisted diagnostic or interpretative tool. Therefore, the concept of "human readers improve with AI" is not applicable here.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
A standalone performance study of an algorithm was not performed. This is a medical device (collagen membrane), not a software or AI/ML algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the animal study:
- Pathology: Evaluation of pathological changes in tissues.
- Histology: Microscopic examination of tissue samples.
- Histomorphology: Quantitative analysis of tissue morphology (e.g., bone formation).
- Micro-CT: Three-dimensional imaging for bone volume and structure analysis.
These are considered objective biological and imaging endpoints, typically interpreted by experts, to establish the "ground truth" regarding the device's in-vivo performance and tissue response.
8. The sample size for the training set
This is not applicable. This device is a physical medical 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 as there is no training set for this type of medical device.

InterOss® Collagen is indicated for filling of extraction sockets to enhance preservation of the alveolar ridge. InterOss Collagen is recommended for:
Filling of extraction sockets to enhance preservation of the alveolar ridge
Filling of periodontal defects in extraction with products intended for Guided Tissue Regeneration (GTR) and Guided Bone Regeneration (GBR)
InterOss Collagen is a combination of InterOss®, an anorganic hydroxyapatite bone substitute, and collagen fibers for use in periodontal, oral and maxillofacial surgery. This product is a composite of 90% InterOss® (granules of size 0.25-1mm) and 10% porcine collagen fibers. InterOss®, which is already a cleared device by the FDA (K151209), is a hydroxyapatite material derived from Australian bovine bone. The osteoconductive mineral structure is produced from bone through a multi-step purification process. Following placement in bony voids or gaps InterOss® acts as an osteoconductive scaffold for the ingrowth of adjacent viable bone. InterOss® gradually resorbs and is replaced with bone during the healing process. The collagen component facilitates the adaptation of Inter Osse to the allowing easier handling. The product is non-pyrogenic, single use only, and terminally sterilized via gamma-irradiation.
The product is available in the following shapes and sizes:
| Type | Weight(mg) | Dimension(mm) | Ref# |

The provided document is a 510(k) premarket notification for the InterOss® Collagen bone grafting material. It describes the device, its intended use, and a comparison to predicate devices, along with non-clinical testing performed to demonstrate substantial equivalence.
However, the document does not contain information about a study proving the device meets acceptance criteria in the context of an Artificial Intelligence (AI) or machine learning device. The "acceptance criteria" and "device performance" in the tables are for the physical and chemical properties and biocompatibility of the bone grafting material itself, not for an AI-powered system evaluating its efficacy or providing diagnostic information.
Therefore, I cannot provide the requested information regarding:
- A table of acceptance criteria and reported device performance for an AI device.
- Sample size used for the test set and data provenance.
- Number of experts and their qualifications for establishing ground truth.
- Adjudication method for the test set.
- Multi-Reader Multi-Case (MRMC) comparative effectiveness study.
- Standalone performance (algorithm only).
- Type of ground truth used.
- Sample size for the training set.
- How ground truth for the training set was established.
This document is for a traditional medical device (bone grafting material), not an AI/ML medical device, and thus the requested AI-specific information is not present.
