Intended Use
NexStat® Plus Topical Hemostat Powder and NexFoam® Plus Topical Hemostat Sponge are intended for use under the care of a health care professional 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 for the treatment of mild bleeding from topical ENT surgical wounds and nosebleeds. It is also indicated for control of bleeding from the skin at percutaneous needle access, vascular access and percutaneous catheter access sites.
Device Description
The Hemostasis NexStat® Plus Topical Hemostat Powder and NexFoam® Plus Topical Hemostat Sponge are sterile, topical wound dressings comprised of plant based polysaccharides. The hemostatic particles and foam quickly dehydrate blood cells, resulting in hemoconcentration of platelets, serum proteins and fibrinogen, leading to clotting that limits and controls bleeding. The NexStat® Plus Topical Hemostat Powder and NexFoam® Plus Topical Hemostat Sponge are identical to the NexStat® Topical Hemostat Powder and NexFoam® Topical Hemostat Sponge cleared for market under 510(k) K102459, with the exception of the cross-linking manufacturing process. The cross-linking process for the manufacture of polysaccharide hemostatic particles is being changed for the NexStat® Plus and NexFoam® Plus devices. The new cross linking process utilizes the identical cross linker used in the predicate Medafor MPH® product subject of K033666. All other materials and processes remain the same as NexStat® and NexFoam®. The indications for use remain the same as NexStat® and NexFoam®
More Information

No
The device description focuses on the material properties and physical mechanism of action (dehydration of blood cells) for hemostasis. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML. The changes described relate to the manufacturing process of the polysaccharide material.

Yes
The device is intended for the temporary treatment of bleeding wounds, which is a therapeutic purpose.

No

This device is a topical hemostat powder and sponge used to control bleeding from wounds. Its function is therapeutic (to stop bleeding), not diagnostic (to identify a disease or condition).

No

The device is described as a topical wound dressing comprised of physical materials (plant based polysaccharides) and is not software.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is a "topical dressing for the temporary treatment of moderate to severely bleeding wounds." This describes a device that is applied directly to the body to control bleeding, not a device used to examine specimens from the body to provide diagnostic information.
  • Device Description: The description explains that the device is comprised of "plant based polysaccharides" that "quickly dehydrate blood cells, resulting in hemoconcentration... leading to clotting." This mechanism of action is a physical process applied externally to the wound, not a test performed on a biological sample.
  • No mention of in vitro testing: There is no mention of the device being used to analyze blood, tissue, or any other biological specimen outside of the body.

IVD devices are specifically designed to be used in vitro (outside the living body) to examine specimens from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.
