The CoAg Medical, LLC StopsBleeding™ Topical Hemostat Powder and Foam are intended for use as a topical dressing for the management of bleeding wounds and are available for prescription use and over-the-counter use.

Prescription: StopsBleeding™ Rx Topical Hemostat Powder and Foam are indicated for use as a topical dressing for the temporary treatment of moderate to severely bleeding wounds such as surgical wounds (post-operative, donor sites, dermatological), cuts and lacerations and are also indicated for control of bleeding from the skin at percutaneous needle access, vascular access and percutaneous catheter access sites. StopsBleeding™ Rx is intended for use under the care of a health care professional.

OTC: StopsBleeding™ OTC Topical Hemostat Powder and Foam are indicated for use as a topical dressing on minor bleeding wounds such as cuts, lacerations and abrasions and for minor nose bleeds.

Device Description

The CoAg Medical StopsBleeding™ Topical Hemostat Powder and Foam are sterile, topical wound dressings comprised of plant based polysaccharides that accelerate the coagulation process to form a stable clot. The hemostatic particles contained in both the powder form and the foam form accomplish this by quickening the natural drying process at the wound site and by concentrating the vital nutrients (proteins and platelets etc.) that the body uses to naturally form a clot. When more of these nutrients are present at a wound site, the body is able to accelerate the cessation of bleeding and allow the healing process to more quickly and naturally occur on its own.

AI/ML Overview

The provided document is a 510(k) summary for the CoAg Medical LLC's "Stops Bleeding Topical Hemostat Powder and Foam." This document describes the device, its intended use, and its substantial equivalence to predicate devices, but it does not contain the detailed information about acceptance criteria and the comprehensive study results (including specifics on test set size, expert panels, and MRMC studies) that you requested.

510(k) summaries are typically high-level documents demonstrating substantial equivalence rather than a full study report with detailed performance metrics against specific acceptance criteria. They generally don't include the granular data points such as the exact sample sizes of test sets, the number and qualifications of experts for ground truth establishment, or clinical study designs like MRMC studies with effect sizes, unless those were pivotal for establishing equivalence in a novel way.

The document mentions "Bench Testing" and "Performance Testing" with conclusions of substantial equivalence, but it doesn't provide the raw data or detailed methodologies of these tests.

Therefore, I cannot provide a table of acceptance criteria and reported device performance, nor can I answer your specific questions about study design elements like sample sizes, expert qualifications, adjudication methods, or MRMC study results based solely on the provided text.

What the document does provide regarding performance and testing is limited to:

Performance Testing: "Comparative water holding capability bench testing and bleeding cessation testing in a porcine animal model demonstrated that the StopsBleeding™ Topical Hemostat Powder and Foam performed substantially equivalent to the primary predicate devices."

This broadly states what was tested and the outcome (substantially equivalent), but not the acceptance criteria for that equivalence in a quantifiable manner, nor the detailed data.

To provide the information you requested, a full clinical study report or a more detailed submission document to the FDA would be necessary.

Dear Mr. Horwath:

This letter corrects our substantially equivalent letter of July 28, 2014.

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. 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.

Substantial Equivalence:

The CoAg Medical StopsBleeding™ Topical Hemostat Powder and Foam are substantially equivalent to the following predicate devices:

Manufacturer	Brand Name	510(k) Number
Hemostasis, LLC	TraumArrest®/BleedArrest®	K070211
Medafor	Bleed-XTM/TraumadexTM	K013225

StopsBleeding™ Topical Hemostat Powder and Foam are technically identical hemostats as the predicates and have the same intended use. The Hemostasis, LLC hemostat is considered the primary predicate for indications for use, technical composition and performance, while the Medafor hemostat predicate has substantially equivalent packaging.

Technological Characteristics:

Technically, the StopsBleeding™ Topical Hemostat Powder and Foam have the same plant based polysaccharide material composition as the predicates. The use of this same plant based polysaccharide in the CoAg and Hemostasis hemostats results in the same mechanism of action, namely dehydration of blood cells and hemoconcentration of platelets and serum proteins leading to clotting.

Biocompatibility:

The CoAg Medical StopsBleeding™ Topical Hemostat Powder and Foam and the predicate hemostats are categorized as a surface device for breached or compromised skin surfaces with prolonged exposure of 24 hours to 30 days in accordance with ISO 10993-1 Biological Evaluation of Medical Devices. These plant based polysaccharides hemostats have demonstrated compliance to cytotoxicity, sensitization and irritation biocompatibility testing and have a long history of safe and effective use.

Sterilization:

The CoAg Medical StopsBleeding™ Topical Hemostat Powder and Foam are sterilized using a gamma radiation method to assure a sterilization assurance level (SAL) of 10 °. The CoAg devices are packaged in the same manner as the predicate devices to assure sterility over their labeled shelf life.

Bench Testing:

Design verification testing was performed on StopsBleeding™ Topical Hemostat Powder and Foam to demonstrate physical and functional requirements were met.

Performance Testing:

Comparative water holding capability bench testing and bleeding cessation testing in a porcine animal model demonstrated that the StopsBleeding™ Topical Hemostat Powder and Foam performed substantially equivalent to the primary predicate devices.

{6}------------------------------------------------

Conclusion:

Through the data and information presented, CoAg Medical, LLC considers the StopsBleeding™ Topical Hemostat Powder and Foam substantially equivalent to the predicate devices already on the market (cleared by the 510(k) process) in terms of indications for use, scientific technology, material composition, design, functional performance, and sterility/packaging and present no new concerns about safety and effectiveness.
