Niti-S Duodenal Comfort Stent is indicated for the palliative treatment of pyloric or duodenal obstructions caused by malignant neoplasms. Niti-S Colonic Comfort Stent is indicated for the palliative treatment of colorectal strictures produced by malignant neoplasms and to relieve large bowel obstruction prior to colectomy in patients with malignant strictures.

The Niti-S Duodenal Comfort Stent and Niti-S Colonic Comfort Stent consist of an implantable metallic stent and an introducer system. The stent is made of nitinol wire and is designed as a flexible, fine mesh tubular prosthesis with several radiopaque markers. The Niti-S Duodenal Comfort Stent has a diameter of 22 mm, while the Niti-S Colonic Comfort Stent is available in diameters of 22 mm and 24 mm. Both stent types are available in lengths of 60 mm, 80 mm, 100 mm, and 120 mm. The stent delivery system accommodates a 0.035 in (0.89 mm) guidewire. It is advanced over the guidewire and passed through an endoscope into the duodenum or colon. Fluoroscopy is recommended to ensure accurate device placement.

Evolution® Duodenal Stent System- Uncovered: This device is used for palliative treatment of duodenal or gastric outlet obstruction and duodenal strictures caused by malignant neoplasms. Evolution® Colonic Stent System- Uncovered: This device is used for palliative treatment of colonic obstruction or colonic strictures caused by malignant neoplasms, and to relieve large bowel obstruction prior to colectomy in patients with malignant strictures.

This flexible, self-expanding stent is constructed of nitinol wire. The stent diameter is increased at either end to help provide resistance to migration. The total length of the stent is indicated by radiopaque markers on the inner catheter. indicating the actual length of the stent at the nominal stent diameter. Introduction System Description: The stent is mounted on an inner catheter, which accepts a 0.035 inch wire guide and is constrained by an outer catheter. The handle allows for desheathing to deploy the stent and resheathing to recapture the stent during stent deployment.

Stent Description: This flexible, self-expanding stent is constructed of nitinol wire. The total length of the stent is indicated by radiopaque markers on the inner catheter, indicating the actual length of the stent at nominal stent diameter. The stent has flanges at both stent ends. Introducer System Description: The stent is mounted on an inner catheter, which accepts a 0.035 inch wire guide and is constrained by an outer catheter. A pistol-grip delivery handle allows stent deployment or recapture.

The WallFlex™ Enteral Duodenal Stent with Anchor Lock Delivery System is indicated for the palliative treatment of gastroduodenal obstructions caused by malignant neoplasms.

The proposed WallFlex™ Enteral Duodenal Stent with Anchor Lock Delivery System consists of two components: an implantable metal stent and a delivery system. The proposed stent is manufactured of Nitinol and has a 22mm body diameter with a 27mm distal flare diameter, and is offered in three lengths, 6cm, 9cm, and 12cm. The Anchor Lock Delivery System consists of a coaxial tubing assembly that constrains the stent on the delivery catheter shaft until the stent is released by retracting the exterior tube.

The Schneider (USA) Inc Enteral Endoprosthesis is indicated for palliation of duodenal strictures caused by malignant neoplasms.

The WALLSTENT® Enteral Endoprosthesis is comprised of two components: the temporary (short-term) implantable metallic stent and the delivery device. The stent is composed of implant-grade cobalt-base superalloy wire braided in a tubular mesh configuration. The design configuration results in a stent that is flexible, compliant and The stent is available in multiple sizes. Physician preference and self-expanding. individual patient condition and/or anatomy will determine the appropriate size chosen.
