Niti-S™ NAGI™ Stent for Pseudocyst Drainage

Category: Biliary Stents

NAGI™ Stent (Pseudocyst drainage)

The Niti-S Nagi™ Stent consists of an implantable metallic stent and an introducer system. The stent is made of Nitinol wire. It is a flexible, fine mesh tubular prosthesis which has radiopaque markers on each end and at the center. The Stent is loaded in the introducer system and upon deployment the body of the stent imparts an outward radial force while both heads impart a horizontal inward force, allowing transmural drainage. Niti-S Nagi™ Stent is Fully Silicone Covered and can be removed; (see Warnings).

In the dynamic world of medical innovation, one breakthrough stands out as a game-changer in gastroenterology: the Niti-S™ Self-Expandable Metal NAGI™ Stent, a remarkable solution for pseudocyst drainage. Pseudocysts, collections of fluid and tissue that can form in the abdomen, often arise as complications of pancreatitis, trauma, or surgery. Traditionally, managing pseudocysts required invasive surgical procedures, carrying significant risks and recovery time.

Enter the Niti-S™ Stent, a cutting-edge device that has revolutionized pseudocyst drainage. This self-expandable metal stent, designed with precision engineering, can be deployed endoscopically. Its flexibility and adaptability ensure secure placement and effective drainage, all while minimizing patient discomfort and recovery time.

The Niti-S™ Stent not only simplifies the pseudocyst management process but also reduces healthcare costs and hospitalization durations. Patients can experience faster relief, fewer complications, and an improved quality of life.

With the Niti-S™ Self-Expandable Metal NAGI™ Stent, gastroenterologists have a powerful tool that exemplifies the ever-advancing capabilities of medical technology in enhancing patient care and outcomes. This innovation is a testament to the relentless pursuit of excellence in the field of gastroenterology
