Indications for Use
The Niti-S Biliary Stent is indicated for the palliation of malignant strictures in the biliary tree.
Device Story
Niti-S Biliary Stent is an implantable, self-expanding tubular device composed of Nitinol wire; designed to restore structure and function of the biliary tree. Device includes an introducer system available in percutaneous or endoscopic configurations. Upon deployment, stent exerts outward radial force on the luminal surface of the duct to establish patency. Used by physicians in clinical settings to treat malignant strictures; provides palliative relief by maintaining ductal patency. Available in diameters of 8mm and 10mm and lengths ranging from 40mm to 120mm. Clinical benefit includes improved biliary drainage in patients with malignant obstructions.
Clinical Evidence
Bench testing only. Biocompatibility assessment performed on patient-contact materials. No clinical data provided.
Technological Characteristics
Self-expanding Nitinol (Nickel-Titanium alloy) wire stent. Available in 8mm and 10mm diameters; 40-120mm lengths. Includes percutaneous or endoscopic introducer systems. Mechanical expansion via radial force. Non-software device.
Indications for Use
Indicated for the palliation of malignant strictures in the biliary tree in patients requiring biliary stenting.
Regulatory Classification
Identification
A biliary catheter and accessories is a tubular flexible device used for temporary or prolonged drainage of the biliary tract, for splinting of the bile duct during healing, or for preventing stricture of the bile duct. This generic type of device may include a bile collecting bag that is attached to the biliary catheter by a connector and fastened to the patient with a strap.
Special Controls
*Classification.* Class II (special controls). The device, when it is a bile collecting bag or a surgical biliary catheter that does not include a balloon component, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.

#### 4. Description:
Taewoong Medical Co., Ltd.
The proposed Niti-S Biliary Stent consists of an implantable metallic stent and a flexible introducer system. The stent is a rigid, flexible, and expandable tubular device made of a Nitinol wire that is intended to be implanted to restore the structure and/or function of the biliary. This device also includes the introducer. Upon deployment, the stent imparts an outward radial force on the luminal surface of the duct to establish patency. There are 2 different types of introducers; percutaneous or endoscopic. The Stent is available in two diameters (8, 10mm), and eight lengths (40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 120mm) of Nitinol Wire.

Dear Ms. Cambria;
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act and the limitations described below. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
The Office of Device Evaluation has determined that there is a reasonable likelihood that this device will be used for an intended use not identified in the proposed labeling and that such use could cause harm. Therefore, in accordance with Section 513(i)(1)(E) of the Act, the following limitation must appear in the Warnings section of the device's labeling:
The safety and effectiveness of this device for use in the vascular system have not been established.
Furthermore, the indication for biliary use must be prominently displayed in all labeling, including pouch, box, and carton labels, instructions for use, and other promotional materials, in close proximity to the trade name, of a similar point size, and in bold print.
