Device Description
ALGS2 Ag Alginate Wound Dressing is a soft, highly absorbent, sterile, single use, nonwoven (Rx version pad or ribbon, OTC version pad only) dressing composed of calcium alginate and 0.95% ionic silver which allows for a maximum of 18 mg of silver for a 4 inch x 4 inch dressing. The silver present in the dressing is to prevent or inhibit growth of bacteria within the dressing absorbs wound fluid and creates a soft and cohesive gel which conforms to the wound surface and assists in maintaining a moist environment. The ALGS2 Ag Alginate Wound Dressing helps maintain a moist wound environment which is conducive to wound healing. The ALGS2 Ag Alginate Wound Dressing is individually packaged in foil pouches and terminally sterilized by gamma radiation.
More Information

No
The device description and performance studies focus on the material properties and antibacterial effectiveness of a wound dressing, with no mention of AI or ML technologies.

Yes
The device is a wound dressing used for the management of acute and chronic wounds, which is a therapeutic purpose.

No

The device description clearly states it is a wound dressing, used for managing acute and chronic wounds and maintaining a moist wound environment. Its function is to aid in healing, not to diagnose a condition.

No

The device description clearly indicates it is a physical wound dressing composed of calcium alginate and ionic silver. It is a tangible 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 states that the device is a wound dressing used for the management of various types of wounds. This is a topical application for treating a physical condition, not a test performed on a sample taken from the body to diagnose a disease or condition.
  • Device Description: The description details the composition and function of a wound dressing (absorbent material, silver for antibacterial properties, creating a moist environment). This aligns with the characteristics of a medical device used for wound care, not an IVD.
  • Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting specific analytes (proteins, genes, antibodies, etc.)
    • Providing diagnostic information about a patient's health status

Therefore, the ALGS2 Ag Alginate Wound Dressing is a medical device used for wound management, not an In Vitro Diagnostic device.

Dear Albert Rego:

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 (the 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 available at https://www.accessdata.fda.gov/scripts/cdrb/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.

Summary

As shown in the comparison table above and listed in the similarities table below, the Indications for Use, intended use, general design characteristics, mechanism of action, antibacterial activity are substantially equivalent to those of the designated previously marketed medical devices. In addition, both subject and predicate devices are single use, biocompatible, have the same packaging, provided sterile using gamma radiation, and have substantially equivalent absorbency and maximum silver release over 7 days within the dressing. Both subject and predicate devices have the same gelling properties in which the absorption of exudate forms a soft cool gel which maintains a moist environment for optimal wound healing.
