Myriad™ Particles is indicated for use in the management of the following wounds:
- · partial and full-thickness wounds
- · pressure ulcers
- venous ulcers .
- diabetic ulcers .
- chronic vascular ulcers .
- . tunneled/undermined wounds
- Surgical wounds (donor sites/grafts, post-Moh's surgery, post-laser surgery, podiatric, . wound dehiscence)
- . trauma wounds (abrasions, lacerations, partial-thickness burns, and skin tears)
- · draining wounds
Myriad™ Particles is derived from an extracellular matrix primarily composed of ovine collagen and is supplied as a sterile particulate.
The provided document is a 510(k) premarket notification for a medical device called "Myriad™ Particles." This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, rather than proving a device meets specific clinical performance acceptance criteria through the kind of study described in the prompt.
Therefore, the document does not contain the information requested regarding acceptance criteria and performance studies. The key points from the document that illustrate this are:
- No Clinical Performance Data Used for Substantial Equivalence: Section 5.6 explicitly states: "Substantial equivalence was not based on an assessment of clinical performance data." This means a human clinical study to prove performance was not conducted for this 510(k) submission.
- Focus on Substantial Equivalence through Technological Characteristics and Non-Clinical Data: The document relies on comparing the technological characteristics of Myriad™ Particles to its predicate device (Endoform™ Dermal Template) and presenting non-clinical (bench and biocompatibility) testing. The primary difference highlighted is the device presentation (powder vs. sheet format).
- No mention of AI/ML components: The device is a wound dressing, and there is no indication that it incorporates any artificial intelligence or machine learning components. Therefore, an MRMC comparative effectiveness study or standalone algorithm performance assessment would not be applicable.
In summary, the provided text does not describe a study designed to prove the device meets specific acceptance criteria in the way a clinical performance study for an AI/ML device would. It focuses on demonstrating substantial equivalence to an existing device through non-clinical means.

Dear Tina O'Brien:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for

devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medicaldevices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (https://www.fda.gov/medical-device-advice-comprehensive-regulatoryassistance/contact-us-division-industry-and-consumer-education-dice) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).

5.4 Technological Characteristics Comparison
The primary difference between the subject and predicate devices is the device presentation (powder vs. sheet format). An additional inner tray has been implemented to facilitate dispensing of the new device presentation.
The subject Myriad™ Particles® device is identical to the predicate Endoform™ Dermal Template with respect to raw material, tissue processing (with the exception of the steps to convert the ECM material from a sheet to a particulate), terminal sterilization, intended use, and indications for use.
Cook Biotech's ECM Powder (K152033) is noted as a reference device to highlight a similar design modification to a 510(k) cleared animal-derived collagen dressing sheet format to a powdered form, both intended for use in wound care.

5.5 Non-Clinical Performance Data
Bench testing included physical specifications, packaging, EO residuals, bioburden, and endotoxin testing. Results of the testing confirms that the proposed device meets all product specifications for the intended use and demonstrates substantial equivalence to the predicate device.
The following biocompatibility testing was conducted in accordance with ISO 10993-1 based on the device's classification as 'breached or compromised surface' contact for a 'permanent' duration:
- Cytotoxicity (MEM Elution) ●
- Delayed Type Hypersensitivity (Sensitization) ●
- Irritation (intracutaneous reactivity)
- Implantation
- Toxicological risk assessment ●
- Heavy metal testing ●
5.6 Clinical Performance Data
Substantial equivalence was not based on an assessment of clinical performance data.
5.7 Conclusions
Myriad™ Particles is as safe and effective and has the same intended uses, indications, and principles of operation as Endoform™ Dermal Template. The minor differences between the Myriad™ Particles presentation and the predicate device do not raise different questions of safety or effectiveness. Performance data demonstrate that Myriad™ Particles is as safe and effective as the predicate device.
