The device description focuses on the material properties and physical mechanism of action (absorption, gelling, coagulation activation) of a cellulose-based matrix. There is no mention of software, algorithms, data processing, or any terms related to AI/ML. The performance studies evaluate the hemostatic efficacy and biocompatibility of the material itself, not the performance of an AI/ML model.
Yes
The device actively aids in blood coagulation and accelerates clot formation to control bleeding in traumatic wounds, which is a therapeutic function.
No
Explanation: The device is designed to control bleeding by promoting blood coagulation and does not collect or analyze data about the patient's health condition to determine the nature of a disease or injury.
No
The device description clearly states it is a "woven matrix of fibers made from cellulose" and describes its physical properties and mechanism of action as a physical hemostatic material, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) outside of the body to provide information for diagnosis, monitoring, or screening.
- BloodSTOP iX Battle Matrix Function: This device is applied directly to a wound on the body to control bleeding. It interacts with blood in situ (at the wound site) to promote clotting. It does not analyze a sample taken from the body in a laboratory setting.
- Intended Use: The intended use clearly states "external temporary control of minor to moderate bleeding of traumatic wounds." This is a therapeutic function, not a diagnostic one.
- Device Description: The description focuses on its physical properties and how it interacts with blood at the wound site to form a gel and aid coagulation.
- Performance Studies: The performance studies evaluate its ability to stop bleeding in a live animal model, not its ability to accurately detect or measure substances in a sample.
Therefore, based on the provided information, BloodSTOP iX Battle Matrix is a hemostatic device used for wound care, not an In Vitro Diagnostic device.

Device Description
BloodSTOP iX Battle Matrix is a biocompatible, non-irritating, woven matrix of fibers made from cellulose. Using a proprietary process, regenerated cellulose is etherified and oxidized to make a watersoluble, hemostatic matrix. When applied to a wound, BloodSTOP® iX Battle Matrix absorbs blood and other body fluids, transforms into a gel, actively aids in blood coagulation, and adheres to the wound with a protective translucent layer. BloodSTOP iX exerts its pro-coagulant activity by activating the intrinsic coagulation pathway, accelerating clot formation. Its water solubility allows for easy removal through rinsing without disruption of the clotted wound surface. BloodSTOP iX Battle Matrix is provided sterile in a simple to use format that readily conforms to a wound: 3"x24" strip, z-folded to an 8-layer 3"x3" pad.

To the right of the word "PLUS" is a graphic of a plus sign, with one plus sign in white and another in orange, slightly offset.
- QuikClot eX (K072474. also marketed as QuikClot Combat Gauze): same intended use and a) similar technological characteristics.
BloodSTOP iX Battle Matrix and QuikClot eX (Combat Gauze) have the same intended use: temporary external use for the control of bleeding of traumatic wounds.
BloodSTOP iX Battle Matrix is technologically similar to the predicate device QuikClot eX (Combat Gauze) in design in that both products are in presented in an intuitive, easy-to-use, sterile, dressing format that readily conforms to a wound. Both are free of animal-derived components. They have the same principle of operation in that, when applied to a wound with pressure, they exert hemostatic action to control bleeding. BloodSTOP iX Battle Matrix, upon contact with blood, transforms into a gel, adheres to the wound, and activates the intrinsic coagulation pathway, accelerating clot formation. The mechanism of QuikClot eX (Combat Gauze), containing the hemostatic mineral agent kaolin in a gauze matrix, is similar: when contacting blood, it initiates the clotting process by activating the intrinsic coagulation pathway.
The products are technologically different in hemostatic agent. In QuikClot eX, the agent is kaolin mineral powder. With BloodSTOP iX Battle Matrix, the etherified, oxidized, regenerated cellulose matrix itself initiates hemostasis. Although the hemostatic components of these two products are different, their mechanism of action and outcome is substantially similar.
- b) BloodSTOP iX Hemostatic Gauze (K072681): similar intended use and same technological characteristics
BloodSTOP iX Battle Matrix and BloodSTOP iX Hemostatic Gauze have similar indication statements as both are for temporary external use to control surface bleeding. The intended use of BloodSTOP iX Battle Matrix also includes bleeding of traumatic wounds.
BloodSTOP iX Battle Matrix and BloodSTOP iX Hemostatic Gauze are identical in format and chemical composition, both being etherified, oxidized, regenerated cellulose dressings produced by LifeScience PLUS, Inc., in the identical manufacturing process. BloodSTOP iX Battle Matrix is larger in size.
7. Performance Data
Performance testing included in this submission demonstrates that BloodSTOP iX Battle Matrix is as safe and as effective as the legally marketed predicates:
- Biocompatibility testing for the intended body contact and duration
- . In-vivo testing in a severe bleed wound model
Biompatibility Testing a)
Biocompatibility testing recommended in ISO 10993-1 and additional tests recommended in FDA Blue Book Memo, G95-1, for evaluation of devices in contact with breached or compromised surfaces for a limited duration, were undertaken for BloodSTOP iX products. Test results demonstrate BloodSTOP iX Battle Matrix safety in that it is biocompatible for the intended use:

| Intracutaneous Reactivity | Non-irritating |
| Sensitization/Hypersensitivity | Non-sensitizing |
| Primary Skin Irritation | Non-irritating |
| Systemic Injection, Acute Systemic Toxicity | Non-toxic |
| Systemic Injection, Subchronic/ Chronic | |
| Toxicity | Non-toxic |
| Subcutaneous Implantation | Non-reactive |
b) Hemostatic Efficacy
In vivo testing demonstrates the safety and efficacy of BloodSTOP iX Battle Matrix for the intended use, using a widely recognized 6mm femoral artery injury model in swine. The results demonstrate that the new device is as safe and as effective as QuikClot eX (Combat Gauze) in achieving hemostasis as measured by time to hemostasis, blood loss, maintenance of MAP, 3-hour survival, hematological measures of clot stability in simulated walking test, and absence of conclusive distant adverse effects.
8. Conclusion
BloodSTOP iX Battle Matrix has the same intended use as QuikClot eX (Combat Gauze) and is similar in technological characteristics. Both products are sterile wound dressings, a widely and intuitively used format. They are applied and removed in the same way and have the same principle of operation. The difference in technological characteristics is in the hemostatic agent. BloodSTOP iX Battle Matrix has been shown to be equivalently biocompatible for the contact and duration, to achieve equivalent (or better) hemostasis in every measure evaluated in the benchmark animal model, with equivalent clot stability during animal movement. In an abundance of caution, labeling contains a warning about potential risk of embolism in areas of exposed vasculature.
BloodSTOP iX Battle Matrix has a similar intended use and the same technological characteristics as BloodSTOP iX Hemostatic Gauze.
BloodSTOP iX Battle Matrix is substantially equivalent to the predicate devices based on technological characteristics and performance data including bench, pre-clinical and usability testing.
