A hemostatic powder that puts you in control

The Nexpowder™* endoscopic hemostatic system is a noncontract, nonthermal and nontraumatic hemostatic powder sprayed through a catheter. Featuring a proprietary powder-coating technology, Nexpowder™* minimizes catheter clogging and particle scattering, 1-3 giving you more control and better visibility.

Why Nexpowder™*?

  • A proprietary powder coating technology that minimizes catheter clogging and particle scattering 
  • Unique delivery system that doesn’t rely on CO2 or air compressors
  • Distinctive blue color so you can have the confidence the lesion is fully covered
  • Highly adhesive gel that reacts to moisture, not just active bleeding, so it can be used in a variety of clinical applications

Hemostatic powder technology that puts you in control.3,4,5

The Nexpowder™* endoscopic hemostasis system is a powder that can be sprayed to an ulcer site, applying an endoscopic hemostatic agent. As a hydrophilic biocompatible adhesive material, it is composed of succinic anhydride (ε-poly-(L-lysine)) and oxidized dextran. 

The Nexpowder™* system forms the adhesive gel after making contact with the water or blood by reversible crosslinking. Crosslinked gel helps prevent bleeding, loss of body fluid and contamination of the ulcer site by adhering to the bleeding site in the gastrointestinal tract and then gel degrades within 1 day to 3 days.3,4,5

Nexpowder™* Endoscopic Hemostasis System Clinical Summary

A prospective study assessed the feasibility of Nexpowder™* application in refractory upper gastrointestinal bleeding in 17 patients, and has shown:

  • Successful application in all patients
  • Initial hemostasis in 16 out of 17 patients: 94%.
  • Rebleeding within 30 days was seen in 3 out of 16 patients (19%)
  • Remnants of the gel was evident in 11 out of 16 patients (69%) at the second examination after 24 hours1

In a retrospective study in Korea, monotherapy with Nexpowder™* was administered to 56 patients with active bleeding. Immediate hemostasis was achieved in 96.4% (54/56) with a rebleeding rate of 3.7% (2/54) and no adverse events.2
