Description

The Nexpowder NHS03 is a sophisticated, sterile, single-use endoscopic hemostasis system engineered specifically for the management of non-variceal gastrointestinal (GI) bleeding. By integrating a proprietary biocompatible powder with a precision-engineered delivery device, the NHS03 provides clinicians with a reliable tool for rapid hemorrhage control.

Distributed and verified through the ALLWILL Smart Center, every NHS03 kit undergoes rigorous inspection and is maintained within a controlled supply network to ensure it is clinical-ready for immediate emergency or elective deployment.


Core Technology & System Components

The NHS03 system is designed to overcome the traditional challenges of powder-based hemostats, such as catheter clogging and unpredictable scattering. The kit is a complete, standalone solution comprising:

  • Integrated Spray Body: Features an internal pump and battery-powered drive, eliminating the need for external CO2 canisters or air lines.

  • Precision Delivery Catheter: Developed with proprietary anti-clogging technology to ensure a consistent, laminar flow of powder even in high-moisture environments.

  • High-Visibility Powder Vial: Contains a specialized biocompatible powder tinted with Brilliant Blue FCF for enhanced endoscopic visualization.


Mechanism of Action: The Adhesive Gel Shield

The Nexpowder NHS03 utilizes a physical mechanism rather than a biochemical clotting cascade. This makes it effective even in patients with coagulopathies or those on anticoagulant therapy.

  1. Contact & Hydration: Upon reaching the bleeding site, the powder reacts instantly with blood or gastrointestinal fluids.

  2. Gel Transformation: It transforms into a highly adhesive, protective gel barrier that mechanically seals the ruptured vessels.

  3. Acid Shielding: The resulting gel layer shields the underlying lesion from the corrosive effects of gastric acid, promoting an environment conducive to natural healing.

  4. Natural Degradation: The biocompatible barrier remains stable during the critical rebleeding window and naturally degrades and exits the system within 72 hours.


Clinical Applications and Indications

The Nexpowder NHS03 is versatile, functioning as a primary tool or a reliable backup in complex GI cases.

  • First-Line Therapy: Immediate application for active non-variceal hemorrhages.

  • Adjunctive Use: Combined with mechanical (clips) or thermal (cautery) methods to ensure complete seal of the periphery.

  • Salvage Therapy: Used when traditional endoscopic modalities have failed to achieve hemostasis in refractory cases.

  • Post-Procedural Prophylaxis: Application following Endoscopic Mucosal Resection (EMR) or Endoscopic Submucosal Dissection (ESD) to prevent delayed bleeding.


Key Clinical Advantages

  • Superior Success Rates: Clinical data demonstrates a 94% immediate hemostasis success rate with a remarkably low rebleeding rate of only 3.7%.

  • Precision Targeting: The delivery system allows for localized application, minimizing “snowstorm” effects that can obscure the endoscopic view.

  • Enhanced Visibility: The distinctive blue color allows clinicians to visually confirm that the entire lesion and its margins are fully covered.

  • Non-Contact Delivery: Unlike clips or probes, the powder is applied from a distance (1–2 cm), reducing the risk of further mechanical trauma to fragile tissue.


Treatment Process & Technical Guidelines

For optimal outcomes, clinical teams should follow the standardized Nexpowder application protocol:

  • Preparation: Connect the delivery catheter to the spray body and ensure the powder vial is securely attached.

  • Positioning: Advance the catheter through the endoscope channel. Position the tip 1–2 cm from the target lesion. Avoid direct contact between the catheter tip and fluid to prevent premature occlusion.

  • Deployment: Activate the spray body. The internal pump will deliver a controlled burst of powder.

  • Confirmation: Use the endoscopic camera to verify the formation of the blue adhesive gel. Apply additional layers if necessary until the bleeding is fully arrested.

Frequently Asked Questions

What are the primary indications for using the Nexpowder NHS03?

The NHS03 is indicated for the management of active, refractory, or post-procedural non-variceal gastrointestinal bleeding. It can be utilized as a primary hemostatic agent, an adjunctive therapy alongside clips or cautery, or as a salvage treatment when other endoscopic modalities fail to stabilize the patient.

How does the NHS03 prevent catheter clogging during procedures?

The system utilizes proprietary anti-clogging technology and a dedicated internal pump system. This design maintains a consistent air pressure and powder flow, significantly reducing the risk of moisture-induced blockages that often plague traditional powder delivery systems, thereby ensuring uninterrupted procedural workflows and precise targeting of the lesion.

What is the clinical success rate of Nexpowder for immediate hemostasis?

Clinical data indicates a high performance profile for the Nexpowder NHS03, achieving an immediate hemostasis success rate of 94%. Additionally, the system is associated with a low rebleeding rate of approximately 3.7%, providing clinicians with a dependable solution for both acute stabilization and long-term lesion protection.

Are there any specific contraindications for the Nexpowder NHS03?

Yes, while the powder is biocompatible, it should not be used in patients with a known hypersensitivity to Brilliant Blue FCF, which is the dye used for endoscopic visibility. Furthermore, because the powder formulation may contain lactose-derived components, it is contraindicated for patients with severe lactose intolerance.

How long does the hemostatic gel remain at the bleeding site?

Once the powder contacts fluid and forms an adhesive protective gel, it remains at the site to seal the wound and shield it from gastric acid. The material is designed to naturally degrade and pass through the gastrointestinal tract, typically disappearing entirely within 72 hours of application.

How should the catheter be positioned for the most effective application?

For optimal deployment and to prevent the catheter tip from clogging, the tip should be positioned 1 to 2 cm away from the bleeding site. This distance allows the powder to disperse effectively across the lesion while preventing the catheter from making direct contact with blood or fluids.
