The device description focuses on the physical components and materials of the stent and delivery system. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML. The performance studies are focused on physical properties and equivalence to predicate devices.
Yes
Explanation: The device is indicated for the "palliative treatment of biliary strictures produced by malignant neoplasms, relief of malignant biliary obstruction prior to surgery and for indwell up to 12 months in the treatment of benign biliary strictures secondary to chronic pancreatitis." These are therapeutic interventions aimed at treating a medical condition.
No
The device is a stent system used for palliative treatment of biliary strictures and malignant biliary obstruction. Its function is therapeutic (to relieve obstruction), not diagnostic (to identify or characterize a condition).
No
The device description explicitly states that the device consists of a self-expanding metal stent and a delivery system, which are physical hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for the palliative treatment and relief of obstruction within the biliary tree. This involves a direct intervention on the patient's anatomy.
- Device Description: The device is described as a self-expanding metal stent and a delivery system. This is a physical implant designed to be placed within the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue samples, etc.) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used outside the body to analyze samples and provide diagnostic information. This device is used inside the body for therapeutic purposes.

Device Description
The WallFlex™ Biliary RX Stent System is available in the following stent configurations: Uncovered, Fully Covered. The WallFlex Bliary RX Stent System consists of a self-expanding metal stent and a delivery system. The self-expanding metal stent consists of Platinum cored Nitinol wires wound together to form a cylinder including flares on both the proximal end and distal end.
WallFlex Fully Covered (FC) and Partially Covered (PC) Stents have a Permalume™ Coating, which is a translucent silicone polymer. The coating is used to reduce the potential for tumor in growth through the stent. The coating is used to reduce the potential for tumor in growth through the stent. The FC and PC stents have a retrieval loop for removal during the initial stent placement procedure, to be used in the event of incorrect placement.
The WallFlex Biliary RX Fully Covered Stent System RMV consist of a flexible delivery system preloaded with a self-expanding billiary metal stent. The stents are available in a fully covered configuration only, and have a Permalume™ Covering, which consists of a translucent silicone polymer, to reduce potential for tumor in growth through the stents also have a retrieval loop for removal during the initial stent placement procedure where the retrieval loop is used in the event of incorrect placement, or for removal following indwell up to 12 months.
The Epic "Billary Stent is a sterile laser cut sent composed of a nickel titanium alloy. The stents are available uncovered.
On both the proximal and distal ends of the stent, radiopaque markers increase visibility of the stent to aid in placement.

Dear Katherine Swanson:
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 (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act and the limitations described below. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at
https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
The OHT3: Office of Gastrorenal, ObGyn, General Hospital, and Urology Devices 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 device's labeling:
1
The safety and effectiveness of this device for use in vascular system has 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.
Please note that the above labeling limitations are required by Section 513(i)(1)(E) of the Act. Therefore, a new 510(k) is required before these limitations are modified in any way or removed from the device's labeling.
The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification if the limitation statement described above is added to your labeling.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (OS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review. the OS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
