Intended Use

HYALOMATRIX® is indicated for the management of wounds including: partial and full-thickness wounds; second-degree burns; pressure ulcers; venous ulcers; diabetic ulcers; chronic vascular ulcers; tunneled/undetermined wounds; surgical wounds (donor sites/grafts, post-Moh's surgery , post-laser surgery, podiatric, wound dehiscence); trauma wounds (abrasions, lacerations, skin tears); and draining wounds. The device is intended for one-time use.

Device Description

HYALOMATRIX is a bilayered, sterile, flexible, and conformable wound dressing that acts as an advanced wound care device. It is comprised of a nonwoven pad entirely composed of HYAFF 11, a benzyl ester of hyaluronic acid, and a semipermeable silicone membrane, which controls water vapor loss, provides a flexible covering for the wound surface, and adds increased tear strength to the device. The HYAFF 11 wound contact layer biodegradable matrix acts as a scaffold for cellular invasion and capillary growth.

AI/ML Overview

The provided text describes a 510(k) submission for the HYALOMATRIX® wound dressing. It focuses on demonstrating substantial equivalence to predicate devices rather than proving performance against specific acceptance criteria through a dedicated study.

Here's an analysis of the provided text in relation to your request:

1. Table of Acceptance Criteria and Reported Device Performance

No explicit acceptance criteria or a "performance study" in the traditional sense (e.g., a clinical trial with predefined endpoints and statistical analysis) are described in the provided text. The submission primarily relies on biocompatibility testing and the assertion that "Clinical experience HYALOMATRIX as a wound dressing supports the safety and effectiveness of the device."

The closest approximations to "reported performance" are the general statements related to biocompatibility:

Acceptance CriteriaReported Device Performance
BiocompatibilityHYAFF 11 (Drug Component)
CytotoxicityNeither cytogenic
HemolysisNot hemolytic
Acute Oral ToxicityLD50 > 5,000 mg/kg
Acute Dermal ToxicityLD50 > 2,000 mg/kg
Ocular IrritationNot an ocular irritant
Dermal IrritationNot a dermal irritant
SensitizationLack of sensitizing effect
GenotoxicityNo evidence of genotoxicity
Implantation (up to 1 year)No treatment-related toxicity; degraded within 4 months
Pyrogenicity (LAL test)Endotoxin levels within specification (≤0.2 EU/mg)
USP XXII (Plastic Containers tests)No toxicity observed; no effect of leachables on safety
Silastic® Medical Adhesive Silicone, Type A (Component)
CytotoxicityCytotoxic effects in multiple cell culture assays (direct contact and extracts)
PyrogenicityNegative
U.S.P. Class VNegative
HemolysisNegative
Implantation (90-day)No noteworthy histological findings
Skin SensitizationNo skin sensitization response
Loctite cured film (Component)
Intracutaneous IrritationNon-irritating
Acute ToxicityNot acutely toxic
CytotoxicityNon-cytotoxic
HemocompatibilityHemocompatible
HemolysisNon-hemolytic
ImplantationNo treatment-related histopathological findings
U.S.P. Physicochemical testsPassed
Overall Device (HYALOMATRIX®)
Safety & EffectivenessSupported by clinical experience (no specific data provided)

Important Note: The "Cytotoxicity" for the Silastic® component is listed as having "cytotoxic effects." This is a critical finding, and it's unusual for a component description to include such a negative result without further context or mitigation strategies. However, the subsequent findings for "Loctite cured film" and the overall conclusion suggest that this might have been related to raw material testing or specific extraction methods, and the final device's performance was considered acceptable for its intended use. Without more detail, it's hard to interpret fully.

2. Sample Size for the Test Set and Data Provenance

  • Sample Size for Test Set: Not applicable. The submission does not describe a specific "test set" in the context of a clinical performance study with a predefined sample size of wounds or patients. The biocompatibility tests used animal models (e.g., guinea pigs for sensitization), in vitro cell cultures, and chemical analyses, but specific sample sizes for these individual tests are not detailed in the summary.
  • Data Provenance: The biocompatibility data is likely from laboratory studies (in vitro and in vivo animal models). There is no mention of country of origin for this data or whether it was retrospective or prospective. The statement "Clinical experience HYALOMATRIX as a wound dressing supports the safety and effectiveness of the device" vaguely implies real-world usage but provides no specifics on the data source, size, or methodology.

3. Number of Experts and Qualifications for Ground Truth

Not applicable. There is no mention of experts establishing a "ground truth" for a test set, as there was no comparative clinical performance study described that would require expert adjudication of results (e.g., wound healing assessment by multiple clinicians). Biocompatibility tests rely on established scientific methods and laboratory protocols rather than expert consensus on a 'ground truth'.

4. Adjudication Method for the Test Set

Not applicable. Since no specific test set or clinical performance study requiring human assessment is mentioned, there is no adjudication method described.

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

No. There is no mention of an MRMC study or any comparative effectiveness study involving human readers with or without AI assistance. This device is a wound dressing, not an imaging or diagnostic AI-powered device.

6. Standalone (Algorithm Only) Performance Study

No. This device is a physical wound dressing and does not involve an algorithm or AI. Therefore, a standalone algorithm performance study is not relevant or described.

7. Type of Ground Truth Used

The "ground truth" in this context is derived from:

  • Biocompatibility test results: These are objective measurements and observations from standardized in vitro and in vivo (animal) tests (e.g., cell viability, hemolytic index, irritation scores, histological findings).
  • Clinical experience: While not explicitly detailed, the reference to "clinical experience" implies that observing actual patient outcomes with the device in practice forms a qualitative basis for safety and effectiveness, but it is not quantified as a "ground truth" through a rigorous study.

8. Sample Size for the Training Set

Not applicable. As this is a medical device (wound dressing) and not an AI/algorithm-based diagnostic or imaging tool, there is no "training set" in the context of machine learning.

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

Not applicable. Since there is no training set mentioned, the establishment of its ground truth is also not applicable.


In summary: The provided 510(k) summary for HYALOMATRIX® focuses on demonstrating substantial equivalence primarily through detailed biocompatibility testing of its components and a general statement about clinical experience supporting its safety and effectiveness. It does not contain information about prospective clinical trials with defined acceptance criteria, sample sizes for test or training sets, expert adjudication, or AI performance studies.

layer to prevent moisture loss.

Biocompatibility The biocompatibility of HYAFF 11 (powder or film), one component of Data: HY ALOMATRIX, was assessed in a series of in vitro and in vivo studies.

Cytotoxicity and hemolysis studies demonstrate that HYAFF 11 films are neither cytogenic nor hemolytic. Acute oral and dermal toxicity studies on HYAFF 11 powder indicate that the lethal dose of HYAFF 11 is greater than 5,000 mg/kg and 2,000 mg/kg, respectively. Irritation studies demonstrate that HYAFF 11 powder is not an ocular or dermal irritant, and a sensitization study provides evidence for the lack of a sensitizing effect. No evidence of genotoxicity was observed in three in vitro assays or one in vivo study. An implantation study of up to 1 year found no evidence of treatment-related toxicity, and demonstrated that the HYAFF 11 film was degraded within 4 months. The Limulus Amebocyte Lysate ("LAL") test is used to assess the pyrogenicity of HYAFF 11 as part of the finished product specifications, and the endotoxin levels are within specification (≤0.2 EU/mg).

No toxicity was observed in USP XXII (Plastic Containers tests) testing, indicating that any potential leachable substances present in HYAFF 11 from the packaging used for HYALOMATRIX have no effect on the safety of this device.

Biocompatibility testing on the Silastic® Medical Adhesive Silicone, Type A included cytoxicity in multiple cell culture assays; pyrogenicity; U.S. P. Class V testing; hemolysis; 90-day implantation; and guinea pig skin sensitization. The material produced cytotoxic effects in multiple cell culture assays when placed in direct contact and when extracts of the material were tested. Pyrogenicity, U.S.P. Class V, and hemolysis assays were negative. Implantation studies with cured material resulted in no noteworthy histological findings, and saline extracts did not produce a skin sensitization response in guinea pigs.

Biocompatibility testing on the Loctite cured film included intracutaneous irritation; acute toxicity; cytotoxicity; hemocompatibility; hemolysis; implantation; and U.S.P. physicochemical tests. The material was nonirritating, not acutely toxic; non-cytotoxic; non-hemolytic; hemocompatible; produced no treatment-related histopathological findings upon implantation; and passed the U.S.P. physicochemical tests.

Performance Data:

Clinical experience HYALOMATRIX as a wound dressing supports the safety and effectiveness of the device.

Conclusions:

The performance data discussed above demonstrate that the device is as safe and effective, and performs as well as the predicate devices.
