At each end, the stent has a larger diameter resulting in a “dumbbell” shaped stent when viewed from an axial cross-section.  The Niti-S Esophageal Stent is provided in three configurations:  the Uncovered type, the Full Covered type and the Both Bare type.  The Uncovered-type stent is available in two diameters (6, 8mm), and five lengths (60, 80, 100, 120, and 150mm).  The Full Covered-type and the Both Bare-type stents are available in three diameters (6, 8, 10mm), and five lengths (60, 80, 100, 120, and 150mm).  It has 10 radiopaque markers.  \nThis device also includes a disposable introducer. Upon deployment, the stent imparts an outward radial force on the luminal surface esophagus to establish patency.  The introducer system consists of an Inner Catheter, Outer Sheath, Hub, Y-connector, Tip and Pusher.  All of the components of the introducers are supplied sterile in a disposable package.  The usable lengths of the introducer is 70cm. \nOther information: \nThe shelf-life of Niti-S Esophageal Stent is 3 years.\nThe package is sterilized using Ethylene oxide. \nThe diameter of compatible guide wire is 0.038 inch (0.97mm). \nDo not use if package is damaged. \nDo not reuse or resterilize.\n","DMExempt":false,"premarketExempt":false,"deviceHCTP":false,"deviceKit":false,"deviceCombinationProduct":false,"singleUse":true,"lotBatch":false,"serialNumber":true,"manufacturingDate":true,"expirationDate":true,"donationIdNumber":false,"labeledContainsNRL":false,"labeledNoNRL":false,"MRISafetyStatus":"MR Conditional","rx":true,"otc":false,"contacts":{"customerContact":[{"phone":"323-692-0028","phoneExtension":null,"email":"minsoo@taewoongusa.com"},{"phone":"+82319960641","phoneExtension":null,"email":"contact@stent.net"}]},"premarketSubmissions":{"premarketSubmission":[{"submissionNumber":"K080782","supplementNumber":"000"},{"submissionNumber":"K243619","supplementNumber":"000"}]},"gmdnTerms":{"gmdn":[{"gmdnCode":"61751","gmdnPTName":"Polymer-metal oesophageal stent","gmdnPTDefinition":"A non-bioabsorbable, expandable, tubular device intended to be implanted into the oesophagus to maintain luminal patency in strictures, prevent tumour in-growth, seal oesophageal fistulas, reduce acute bleeding from oesophageal varices, and/or to treat other lesions causing oesophageal leakage (e.g., anastomotic).
