The device description and performance studies focus on the mechanical and material properties of the balloon catheter, with no mention of AI or ML algorithms for image analysis, decision support, or any other function.
No.
The device's intended use is for the endoscopic removal of biliary stones and for contrast injection, which are diagnostic and interventional procedures, not therapeutic.
No
Explanation: The device is described as being used for endoscopic removal of biliary stones and for contrast injection, which are interventional and therapeutic procedures, not diagnostic ones. While it mentions fluoroscopic visualization for placement, its primary function is not to diagnose a condition.
No
The device description clearly details a physical medical device consisting of a balloon, catheter, lumens, hubs, and a stopcock, all of which are hardware components. There is no mention of software being the primary or sole component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "for endoscopic removal of biliary stones and for contrast injection." This describes a therapeutic and diagnostic procedure performed in vivo (within the body), not a test performed in vitro (outside the body) on biological samples to diagnose a condition.
- Device Description: The description details a physical device (balloon catheter) used for mechanical manipulation and delivery of contrast within the biliary system. This is consistent with a surgical or interventional device, not an IVD.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any other components typically associated with in vitro diagnostic testing.
Therefore, this device falls under the category of a medical device used for interventional procedures, not an in vitro diagnostic device.

Device Description
The subject extraction balloon is comprised of a latex balloon mounted at the distal end of a nylon catheter with three internal lumens. The balloon can be inflated to three diameter sizes, 8.5 mm, 12 mm and 15 mm. Radiopaque bands placed at the distal and proximal ends of the balloon provide fluoroscopic visualization of the balloon location. The catheter length is 275 cm with a diameter of 6.6 Fr. The three lumens correspond to a balloon inflation port, a wire guide port and an injection port. The hubs on the respective lumens are color-coded white, purple, and gray. A stopcock is included at the proximal end of the balloon inflation port to control air movement into or out of the balloon.

§ 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.

Dear Theresa de Prat:
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) 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. 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 located 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.
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
1
801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 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 4. Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
