## Intended Use

NuStat is indicated for temporary control of internal organ space bleeding for patients displaying class III or class IV bleeding. It may also be used for control of severely bleeding wounds and traumatic injuries.

## Device Story

NuStat is a hemostatic wound dressing composed of 65% continuous filament silica and 35% bamboo cellulose rayon fibers, incorporating a radiopaque thread for X-ray detection. Used in clinical settings by healthcare providers, the device is applied to bleeding sites (internal organ spaces, surgical wounds, traumatic injuries). Its principle of operation is physical: the cellulose component absorbs excess fluid, facilitating the physical aggregation of blood cells and clotting factors at the application site. The silica fibers further influence the coagulation cascade via contact activation. The dressing provides temporary hemostasis, aiding in the management of severe bleeding. It is provided sterile in various sizes and configurations (foil, Tyvek, or LDPE pouches). The device is intended for prescription use.

## Clinical Evidence

No human clinical data. Evidence includes bench testing and GLP animal studies (pig liver resection model). Hemostasis achieved within 3 minutes. Radiographic visualization confirmed at placement and 48 hours. No evidence of vascular obstruction, embolization, or infection. Biocompatibility testing per ISO 10993 (cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, genotoxicity) showed no adverse findings. In-vitro clot assessment (PT/aPTT) showed accelerated clotting. Particulate release was substantially equivalent to the predicate.

## Technological Characteristics

Hemostatic gauze composed of 65% silica fiber and 35% bamboo cellulose rayon fiber. Includes radiopaque thread (PP-BaSO4). Dimensions range from 2"x2" to 12"x12". Sterilized via gamma radiation. Mechanism: physical fluid absorption and contact activation of the coagulation cascade. Biocompatibility per ISO 10993. Packaging: Tyvek or LDPE pouches.

## Regulatory Identification

A non-absorbable, hemostatic gauze for temporary internal use is a prescription device intended to be placed temporarily for control of severely bleeding wounds such as surgical wounds and traumatic injuries. The gauze is coated or impregnated with a hemostatic material which may enhance hemostasis by physical means. The device is intended to be removed once the patient is stabilized.

## Special Controls

*Classification.* Class II (special controls). The special controls for this device are:(1) Animal performance testing must demonstrate that the device performs as intended under anticipated conditions of use. Specifically testing must:
(i) Demonstrate that the device is able to achieve hemostasis;
(ii) Demonstrate that the device can be radiographically detected; and
(iii) Assess pertinent safety endpoints including vascular obstruction and adhesion formation.
(2) The device must be demonstrated to be biocompatible.
(3) Non-clinical performance data must demonstrate that the device performs as intended under anticipated conditions of use. The following tests must be performed:
(i) In vitro clot assessment;
(ii) Particulate release testing;
(iii) Physical characterization, including swelling percent and particulate size;
(iv) Chemical characterization;
(v) Radiopacity testing; and
(vi) Mechanical integrity testing, including tensile strength and tear strength.
(4) Performance data must demonstrate the sterility of the device.
(5) Performance data must support the shelf life of the device by demonstrating continued sterility, package integrity, and device functionality over the identified shelf life.
(6) Labeling must include the following:
(i) Instructions for use, including an instruction to remove all visible device components by irrigation;
(ii) The maximum amount of time the device may be left within the body;
(iii) A shelf life;
(iv) A contraindication for intravascular use of the device; and
(v) A warning regarding the potential for adhesion formation.

In combination with the general controls of the FD&C Act, the non-absorbable, hemostatic gauze for temporary internal use is subject to the following special controls:

1. Animal performance testing must demonstrate that the device performs as intended under anticipated conditions of use. Specifically testing must:
a) Demonstrate that the device is able to achieve hemostasis;
b) Demonstrate that the device can be radiographically detected; and
c) Assess pertinent safety endpoints including vascular obstruction and adhesion formation.

2. The device must be demonstrated to be biocompatible.

3. Non-clinical performance data must demonstrate that the device performs as intended under anticipated conditions of use. The following tests must be performed:
a) In vitro clot assessment;
b) Particulate release testing;
c) Physical characterization, including swelling percent and particulate size;
d) Chemical characterization;
e) Radiopacity testing; and
f) Mechanical integrity testing, including tensile strength and tear strength.

4. Performance data must demonstrate the sterility of the device.

5. Performance data must support the shelf life of the device by demonstrating continued sterility, package integrity, and device functionality over the identified shelf life.

6. Labeling must include the following:
a) Instructions for use, including an instruction to remove all visible device components by irrigation;
b) The maximum amount of time the device may be left within the body;
c) A shelf life;
d) A contraindication for intravascular use of the device; and
e) A warning regarding the potential for adhesion formation.

Dear Mary McNamara:

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 (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 located at https://www.accessdata.fda.gov/scripts/cdrh/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.

The<br>NuStat range of<br>hemostatic wound<br>dressings have a<br>number of hemostatic<br>properties that<br>enhance the ability of<br>the dressing to<br>temporarily control<br>bleeding. The<br>cellulose and<br>continuous filament<br>silica influence the<br>contact activation<br>pathway of the<br>coagulation cascade<br>by absorbing blood<br>fluids, resulting in the<br>localized<br>concentration of<br>platelets and clotting<br>factors. The<br>negatively charged<br>fibers of the<br>continuous filament<br>silica simulate the<br>negative ions secreted<br>by activated platelets,<br>which further<br>influence the<br>coagulation cascade.<br>The radiopaque<br>element allows for | Both are hemostatic<br>wound dressings that<br>utilize a matrix of<br>fibers to absorb blood<br>and accelerate the<br>clotting process.
