Intended Use
Axiostat Chitosan Hemostatic Dressing is indicated to control bleeding of lacerations, minor cuts and abrasions.
Device Description
Axiostat is a single use, hemostatic dressing made of 100% chitosan is a wellknown natural polysaccharide generally derived from shellfish which has widely recognized hemostatic properties. When applied on the bleeding site with firm pressure, the Axiostat Chitosan Hemostatic Dressing acts as a mechanical barrier against bleeding. The Axiostat is intended for a maximum duration of use of 24 hours, including bandage changes that may be needed. Axiostat is individually packaged in foil bags and sterilized using gamma irradiation. Axiostat is provided in six different sizes for over the counter use as listed below.
More Information

Not Found

No
The device description and performance studies focus on the material properties and mechanical function of the hemostatic dressing, with no mention of AI or ML.

Yes
The device is indicated to "control bleeding of lacerations, minor cuts and abrasions," which aligns with the definition of a therapeutic device designed to treat or alleviate a medical condition.

No

This device is a hemostatic dressing intended to control bleeding of lacerations, minor cuts, and abrasions. Its function is to act as a mechanical barrier to stop bleeding, not to diagnose a condition or disease.

No

The device description clearly states it is a physical dressing made of chitosan, intended to be applied to wounds. It undergoes biocompatibility and bench performance testing, which are characteristic of physical medical devices, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to "control bleeding of lacerations, minor cuts and abrasions." This is a direct therapeutic action on the body to stop bleeding.
  • Device Description: The description explains how the dressing acts as a "mechanical barrier against bleeding" when applied to the bleeding site. This is a physical interaction with the wound.
  • Lack of IVD Characteristics: An IVD device is used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not involve the analysis of any such specimens.

The Axiostat Chitosan Hemostatic Dressing is a medical device used for wound care and hemostasis, not an in vitro diagnostic device.

Dear Alan Donald:

We have reviewed vour 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. 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.
