The summary describes a hydrogel wound dressing with no mention of software, data processing, or AI/ML terms.
Yes
The device is used for the management of leg ulcers and pressure sores, providing a moist wound healing environment, which is a therapeutic function.
No
The device, Comfeel® Purilon Gel, is a wound dressing used for managing leg ulcers and pressure sores by providing a moist healing environment and encouraging debridement. Its function is therapeutic (healing), not diagnostic (identifying or characterizing a medical condition).
No
The device description clearly states it is a hydrogel wound dressing composed of physical materials (calcium alginate, sodium carboxymethylcellulose, purified water) and supplied in plastic tubes, indicating it is a physical medical device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the management of leg ulcers and pressure sores by providing a moist wound healing environment. This is a therapeutic application, not a diagnostic one.
- Device Description: The device is a wound dressing composed of hydrogel. It is applied externally to a wound. IVDs are typically used to examine specimens (like blood, urine, or tissue) in vitro (outside the body) to provide information about a person's health status.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information about a disease or condition.
Therefore, Comfeel® Purilon Gel is a medical device used for wound care, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
For use in the management of leg ulcers and pressure sores. The gel provides a moist wound healing environment which encourages natural autolytic debridement.

§ 878.4022 Hydrogel wound dressing and burn dressing.
(a)
Identification. A hydrogel wound dressing is a sterile or non-sterile device intended to cover a wound, to absorb wound exudate, to control bleeding or fluid loss, and to protect against abrasion, friction, desiccation, and contamination. It consists of a nonresorbable matrix made of hydrophilic polymers or other material in combination with water (at least 50 percent) and capable of absorbing exudate. This classification does not include a hydrogel wound dressing that contains added drugs such as antimicrobial agents, added biologics such as growth factors, or is composed of materials derived from animal sources.(b)
Classification. Class I (general controls). The device is exempt from the premarket notification procedures in part 807, subpart E of this chapter subject to the limitations in § 878.9.

Dear Mr. Hamer:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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 (the Act). You may, therefore, market your device subject to the general controls provisions of the Federal Food, Drug, and Cosmetic Act (Act) and the following limitations:
- This device may not be labeled for use on third degree burns. 1.
-
- This device may not be labeled as having any accelerating effect on the rate of wound healing or epithelization.
-
- This device may not be labeled as a long-term, permanent, or no-change dressing, or as an artificial (synthetic) skin.
- This device may not be labeled as a treatment or a cure for any type of 4. wound.
The iabeling claims listed above would be considered a major modification in the intended use of the device and would require a premarket notification submission (21 CFR
1
Page 2 - Mr. Richard A. Hamer
807.81).The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval) it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations (CFR),
Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practices (GMP) for Medical Devices: General GMP regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4595. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
