More Information

No
The document describes a wound dressing made of biological materials and does not mention any computational or algorithmic components.

Yes
The device is indicated for the management of various types of wounds, which is a therapeutic function.

No
The device is a wound dressing used for the management of various wounds, not for diagnosing them.

No

The device description clearly states it is a sterile, single-use wound dressing, which is a physical product, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes the device as a wound dressing for managing various types of wounds. This is a therapeutic application, not a diagnostic one.
  • Device Description: The description details the physical composition and form of a wound dressing.
  • Lack of Diagnostic Elements: There is no mention of the device being used to test samples from the human body (like blood, urine, tissue, etc.) to provide information about a disease or condition.
  • Performance Studies: The performance studies focus on bench testing related to the physical and biological properties of the dressing, as well as biocompatibility. These are relevant to a therapeutic device, not a diagnostic one.

IVD devices are used in vitro (outside the body) to examine specimens from the human body to provide information for diagnostic, monitoring, or screening purposes. This device is applied in vivo (on the body) for wound management.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Bench testing conducted included GAG foam characteristics, physical specifications, mechanical strength, endotoxin, and dimensional verification 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

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

Symphony™ devices are part of the Endoform® Dermal Template family of devices to introduce new configurations that include a layer of glycosaminoglycans. Symphony™ maintains the same fundamental technological characteristics as the predicate device with respect to ovine forestomach material, sterilization method, packaging materials, and tissue processing.

The Symphony™ device differs from the predicate only with respect to the addition of a layer of glycosaminoglycans. The devices are available in a variety of sizes. Performance and validation testing executed based on risk analysis of the design changes supports substantial equivalence of the subject device.
