No
The description focuses on the chemical composition and physical mechanism of action of the gel, with no mention of AI or ML technologies.
Yes
The device is intended for hemostasis of bleeding, which is a therapeutic action.
No
PuraStat is described as a sterile gel functioning as a hemostat to stop bleeding, which is a therapeutic rather than a diagnostic function.
No
The device description clearly states that PuraStat is a sterile gel composed of a synthetic peptide and sterile water, provided as a prefilled syringe. This indicates a physical substance and delivery system, not solely 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 PuraStat is for hemostasis (stopping bleeding) in vivo (within the body) during and after endoscopic procedures. This is a therapeutic and procedural application, not a diagnostic test performed on samples in vitro (outside the body).
- Device Description: The description details a gel applied directly to tissue to form a physical barrier. This is a local treatment, not a test that analyzes biological samples to diagnose a condition.
- Lack of Diagnostic Elements: There is no mention of analyzing blood, tissue, or other biological samples to provide diagnostic information. The mechanism of action is purely physical hemostasis.
IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for the diagnosis, monitoring, or treatment of a disease or condition. PuraStat does not fit this description.
N/A
Intended Use / Indications for Use
PuraStat is intended for hemostasis of mild and moderate bleeding post ESD or EMR, as an adjunct, bridge, prophylactic or rescue therapy for intraprocedural venous bleeding or prophylactic therapy to prevent post procedure bleeding, and for primary non-variceal gastrointestinal (GI) bleeding. PuraStat is not indicated for arterial Forrest 1a bleeding.

Device Description
PuraStat is a sterile gel composed of a synthetic peptide and sterile water for injection. It is provided as a prefilled syringe (2.5% peptide content) ready for use as a hemostat. The gel is delivered to the intended application site(s) via a commercially available endoscopic catheter that is attached to the gel-filled syringe via the polypropylene adapter (Class 1 - 510k Exempt) also commercially available (Class 1, 510k Exempt).
PuraStat is completely non-animal and non-plant derived and contains no preservatives that might present a risk of allergic reaction or skin irritation.
Exposure to physiological fluids such as blood causes the peptide solution to quickly form a transparent gel without expansion in volume. PuraStat achieves hemostatic effects by forming a hydrogel matrix barrier that blocks the flow of blood at the site of application.
PuraStat comprises of a synthetic repeating 16-amino acid (RADA-16) oligopeptide in sterile water for injection. In the presence of a bleeding wound, the peptides assemble into a scaffold structure that forms a mechanical barrier over the bleeding site. The solution is filtered and filled into 5-ml syringes made of cyclo-olefin polymers with a high-density polyethylene plunger and a butyl rubber head cap and gasket. Each syringe is filled with either 1, 3, or 5 ml of gel. The device is terminally sterilized, and the resorbable gel is delivered to the intended application site(s) via a commercially available adapter connected to a commercially available catheter. The device is delivered endoscopically via a catheter to the patient.
