1. Description
The Niti-S & ComVi Esophageal Stent consists of the implantable
metallic stent and 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.
Model Name
Niti-S Esophageal Uncovered Stent
Niti-S Esophageal Covered Stent
ComVi Esophageal Stent
The Stent is loaded in introducer system and upon deployment the
stent imparts an outward radial force on the luminal surface of the
esophagus to establish patency.
The Anti-Reflux type Stent is designed to reduce or prevent reflux
post-implantation.
Niti-S Full Covered Esophageal Stents used in benign stricture
can be removed; (see Warnings).
Full Covered Esophageal Stents can be repositioned after
deployment; (see Warnings).
A.
Distal & Proximal Release Introducer
LOCKING SYSTEM(VALVE)
- The introducer system accepts a .038" guidewire. The stent
introducer system is passed over the guidewire into the esophagus.
- The stent is positioned appropriately using the X-ray markers for
guidance under fluoroscopy.
B.
TTS Introducer
- The TTS introducer system has a usable length of 160,180,220
cm
- TTS means Through The endoScope
2. Principle of Operation (Distal Release & Proximal Release)
For Distal release & TTS Introducer systems, the outer sheath is
pulled back by immobilizing the hub in one hand, grasping the
Y-connector with the other hand, and gently sliding the Y-
connector along the 2
Retraction of the outer sheath releases the stent.
