No
The summary describes a mechanical stent and delivery system with no mention of AI or ML capabilities.
Yes
The device is intended for "palliation of malignant strictures in the biliary tree," which describes a therapeutic purpose to alleviate symptoms or improve a condition.
No
This device is a biliary stent system intended for palliation of malignant strictures, which is a therapeutic rather than diagnostic function.
No
The device description clearly states it is a "self-expanding Nitinol stent" supplied with a "triaxial delivery catheter," indicating it is a physical medical device with hardware components, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "palliation of malignant strictures in the biliary tree." This describes a therapeutic intervention performed within the body to treat a condition.
- Device Description: The device is a "self-expanding Nitinol stent" and a "delivery catheter." These are physical devices used for implantation and delivery within the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens in vitro (outside the body) to provide information about a physiological state, health, or disease. IVDs typically involve reagents, calibrators, controls, and instruments used to analyze biological samples like blood, urine, or tissue.
Therefore, the ALIMAXX-B™ Uncovered Biliary Stent System is a therapeutic medical device, not an In Vitro Diagnostic device.

§ 876.5010 Biliary catheter and accessories.
(a)
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.(b)
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.

TRADE OR PROPRIETARY NAME: ALIMAXX-BTM Uncovered Biliary Stent System
CLASSIFICATION/ NAME: Class II, Biliary Cathefer and Accessories (21CFR §876.5010), Product Code FGE
PREDICATE DEVICES: ALIMAXX-BTM Uncovered Biliary Stent System (K072720)
DEVICE DESCRIPTION:
The ALIMAXX-BTM Uncovered Biliary Stent System is a sterile, single-use, self-expanding Nitinol stent that is supplied with the stent pre-loaded on the triaxial delivery catheter of the delivery system. The delivery system is available in two designs, one for endoscopic placement (working length is 185 cm) and another for transhepatic placement (working length is 80 cm).
INTENDED USE:
The ALIMAXX-B™ Uncovered Biliary Stent System is intended for palliation of malignant strictures in the biliary tree.
TECHNOLOGICAL COMPARISON:
The modifications proposed are being made to the endoscopic delivery system catheter to improve visibility during stent placement. These changes are not being made to the transhepatic delivery system catheter. The modified device has the identical intended use and employs the same fundamental technology as the predicate device.
The proposed design, material, and labeling changes that triggered the submission of this notification consist of the following:
- . Segments of the endoscopic delivery system catheter shall have material and colorant changes made to improve the endoscopic and fluoroscopic visibility of the position of the stent during placement.
- Changes have been made to the Instructions for Use to identify Merit Medical Systems, Inc. . (Merit) as the manufacturer of the device, as Alveolus Inc., the submitter of the original 510(k), is no longer the legal manufacturer. Additional changes in instruction have been added to address the modifications made to the delivery system catheter's increased visibility during endoscopic placement of the stent.

Note that the proposed modifications are only to be made to the endoscopic delivery system catheter. Neither the transhepatic delivery system catheter nor the biliary stent will be modified.
PERFORMANCE TESTING:
Design verification and design validation studies have been completed. The results demonstrate that the risks associated with the design modifications, as identified in Merit's ALIMAXX-B™ uncovered biliary stent system Clinical Risk Assessment (CRA), have met all of their pre-determined acceptance criteria. Additionally, acceptable controls used to mitigate the identified risks have been incorporated into the devices specifications.
SUMMARY OF SUBSTANTIAL EQUIVALENCE:
Based on:
- . Merit's conformance with Design Control requirements;
- Analyses of risks associated with the modified device; and .
- Results of verification and validation tests performed to address risks identified in Merit's Risk . Assessment demonstrating that predetermined acceptance criteria have been met and risks have been adequately controlled,
Merit concludes that the modified devices are as safe and effective as, and perform as well as, or better than, the predicate devices.

Dear Ms. Holloway:
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.

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.
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 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
