Boston Scientific Ultraflex Esophageal NG Stent System M00513850
The Ultraflex™ Esophageal NG Covered Stent is a sterile, self-expanding nitinol stent with an 18 mm body diameter and 23 mm proximal flare. It measures 12 cm overall, with a 9 cm covered segment, and utilizes a proximal-release delivery system compatible with 0.038″ Jagwire. Designed for managing malignant esophageal strictures and sealing fistulas with stable anchoring.
Constructed from single-strand knitted nitinol, this stent combines flexibility and radial force to maintain esophageal patency throughout peristalsis. The elongated proximal flare and green sutures enhance positional stability and visibility during placement, reducing risk of migration and food impaction. Its proximal-release mechanism enables precise deployment guided endoscopically, potentially without fluoroscopy. The device is MRI-conditional at 1.5 T and 3 T under specified SAR conditions, supporting safe imaging post-implantation.
