Intended Use
The Axiostat Patch is intended for local management of bleeding wounds and to provide a barrier to bacterial penetration of the dressing for patients and for the rapid control of moderate to severe bleeding. The dressing is indicated for the following wounds: lacerations, abrasions, surgical debridement sites, skin surface puncture sites. vascular procedure sites and sites involving percutaneous catheters, tubes and pins.
Device Description
The Axiostat Patch is a sterile, single use, non-absorbable hemostatic dressing. It is composed of chitosan a well-known natural polysaccharide generally derived from shellfish which has widely recognized hemostatic properties. When applied directly to a wound with firm pressure, the dressing controls bleeding and provides a barrier against bacterial penetration. The hemostatic dressing can be removed after the clotting has occurred but should not remain on for more than 24 hours. The hemostatic dressing is not intended to be implanted. The Axiostat Patch is individually packaged in moisture proof packs and terminally sterilized using gamma irradiation.
More Information

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

Yes
The device is described as a hemostatic dressing intended for local management of bleeding wounds and to provide a barrier to bacterial penetration, which are therapeutic actions.

No

The device description and intended use clearly state that the Axiostat Patch is a hemostatic dressing intended for the local management of bleeding wounds and to provide a barrier to bacterial penetration. Its function is to control bleeding and protect the wound, not to diagnose any condition.

No

The device description clearly states it is a sterile, single-use, non-absorbable hemostatic dressing composed of chitosan, which is a physical material. The performance studies also focus on the physical and biological properties of this material. There is no mention of software components.

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

Here's why:

  • Intended Use: The intended use is for the local management of bleeding wounds and to provide a barrier to bacterial penetration. This is a direct therapeutic and protective function applied to the body.
  • Device Description: The device is a sterile, single-use, non-absorbable hemostatic dressing applied directly to a wound.
  • Mechanism of Action: It controls bleeding and provides a barrier against bacterial penetration through direct contact with the wound.
  • No mention of in vitro testing: The description and performance studies focus on the device's interaction with the wound and its ability to control bleeding and act as a barrier in vivo (in the body) or in simulated in vivo conditions (animal studies). There is no indication that the device is used to test samples outside of the body to diagnose a condition or provide information about a patient's health status.

IVD devices are typically used to examine specimens (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. The Axiostat Patch does not perform this function.

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

The Subject Device has been evaluated through a series of nonclinical studies:
a. Biocompatibility testing: Performed per ISO 10993-1:2009, section "Surface devices used on Breached or compromised surface with limited contact duration (≤24 hrs)". Tests included Cytotoxicity (ISO 10993-5, non-cytotoxic), Skin Sensitization (ISO 10993-10, non-toxic), Intracutaneous Reactivity (ISO 10993-10, non-toxic), Acute Systemic Toxicity (ISO 10993-11, non-toxic), Material-Mediated Pyrogenicity (ISO 10993-11, non-pyrogenic), and Bacterial Endotoxin Test (USP 85, complies).
b. Heavy metal testing: Subject Device met USP-232 limits for elemental impurities.
c. Bench performance testing: Evaluated for Appearance, Moisture Content, Absorbency, pH, Integrity test, Tensile strength of product, and In vitro blood clotting test using in house protocols.
d. Barrier to bacteria testing: Axiostat Patch (n=3) and gauze (n=3) were challenged with 10^6 cells of Pseudomonas aeruginosa (ATCC 9027), Staphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 14169), Enterococcus faecalis (ATCC 29212), Proteus mirabilis (ATCC 12453), and Staphylococcus epidermidis (ATCC 12228) for 24 hours. No bacterial growth was observed on plates with Axiostat Patch, while all plates with cotton gauze showed bacterial growth. This demonstrated the device's capacity as a bacterial barrier.
e. Animal studies: Evaluated using procedures described in "Safety Evaluation of New Hemostatic Agents, Smectite Granules, and Kaolin-Coated Gauze in a Vascular Injury Wound Model in Swine; Kheirabadi, et al., J Trauma. 2010 Feb:68(2):269-78." The Subject Device successfully achieved hemostasis in under 5 minutes in all test animals, with no rebleeding observed during a two-hour observation period.

d. Barrier to bacteria testing

This study was performed to evaluate the barrier to bacteria property of the Axiostat Patch. In this test, the Axiostat Patch (n=3) was used as a test sample and a similarly sized gauze (n=3) was used as the control sample. Samples were challenged with 106 cells of three gram-positive and three gram-negative bacterial species.

After challenging for the maximum use-life (i.e. 24 hrs.), the dressings were removed. Then, the plates without the dressing were incubated to observe for the presence/absence of bacterial growth. The following organisms were used:

  • Pseudomonas aeruginosa (ATCC 9027)
  • 9 Staphylococcus aureus (ATCC 6538)
  • Escherichia coli (ATCC 14169)

10

  • . Enterococcus faecalis (ATCC 29212)
  • . Proteus mirabilis (ATCC 12453)
  • . Staphylococcus epidermidis (ATCC 12228)

No bacterial growth was observed in the plates containing Axiostat Patch, whereas all plates containing cotton gauze showed bacterial growth. These results demonstrate the capacity of the Axiostat Patch to act as a barrier to bacterial penetration through the device.

e. Animal studies

The Axiostat Patch was evaluated using the animal testing procedures described in "Safety Evaluation of New Hemostatic Agents, Smectite Granules, and Kaolin-Coated Gauze in a Vascular Injury Wound Model in Swine; Kheirabadi, et al., J Trauma. 2010 Feb:68(2):269-78." This study was performed at an outside independent laboratory.

The Subject Device successfully achieved hemostasis in under 5 minutes in all test animals, and no rebleeding was observed in any animals during the observation period of two hours. Further, there were no thrombi or blood clots in the lumens of blood vessels at the repair site in the Axiostat treated animals.

8. STERILIZATION AND PACKAGING

The Axiostat Patch is packaged in moisture proof packs. The product is terminally sterilized using gamma radiation to a sterility assurance level (SAL) of 10-6. The dose of gamma radiation has been optimized and validated per ISO 11137-2.

Following gamma sterilization, the package integrity was subjected to sterile barrier testing to validate a shelf life of 5 years. The stability and effectiveness of packaging of the sterilized product during the shelf life was confirmed by real time (to support 5-year shelf life) and accelerated stability studies.

The following tests were performed periodically in the validation of 5-year shelf life.

  • Seal strength test as per ASTM F88. .
  • . Dye penetration test as per ASTM F1929-15.
  • Sterility test as per US Pharmacopeia . .
  • Bacterial endotoxin test per US Pharmacopeia . .
  • Bench performance tests to validate the shelf life of the product .
    • i. Appearance
    • ii. Absorbency
    • iii. pH testing
    • iv. Moisture content
  • . Tensile strength for Patch

9. CONCLUSION

The Axiostat Patch is substantially equivalent to the predicate devices with respect to intended use, Indications for Use, design, material, sterilization, and biocompatibility.
