Substantial equivalence supported by bench testing, including insertion/withdrawal, balloon diameter, infusion performance, junction strength, balloon burst, dimensional analysis, fatigue, kink stability, and radiopacity. Biocompatibility testing conducted per ISO 10993-1.

Technological Characteristics

Single-use biliary catheter; inflatable balloon, tube, branch, injection port, air feeding port, stopcock. Materials include natural rubber latex for balloon. Sterilization via ETO. No electrical components. Dimensions: B5-2Q (1.95mm diameter, 11.0mm inflated), B7-2Q/2LA (2.55mm diameter, 13.0mm inflated).

Indications for Use

Indicated for patients requiring biliary or pancreatic stone retrieval or contrast medium injection during ERCP procedures using Olympus endoscopes.

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.

Dear Eve Smith:

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. 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.

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"

Your device is also subject to, among other requirements, the Quality System (QS) 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 QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 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 (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-reporting-combination-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.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E).

# Indications for Use

The DISPOSABLE BALLOON CATHETER B5-2Q, B7-2Q/2LA have been designed to be used with Olympus endoscopes to inject contrast medium into the biliary or pancreatic track. They can also be used for retrieval of biliary or pancreatic stones.

# Principle of Operation

The Balloon Catheters are constructed of an inflatable balloon, tube, branch, injection port, air feeding port, and stopcock.

Prior to use, a sterile syringe is attached to the air feeding port and injects air into the tube to inflate the balloon to the specified volume to confirm that the balloon inflates properly. The balloon is then deflated completely, and the tube is inserted into the instrument channel of the endoscope and advanced to the target area, where the balloon is inflated to allow for biliary or pancreatic stone removal or contrast medium injection through the injection port. When the procedure is completed, the balloon is deflated and the tube is removed from the patient.

# Comparison of Technological Characteristics

Table 1 compares the DISPOSABLE BALLOON CATHETER B5-2Q, B7-2Q/2LA to the predicate device with respect to intended use, and technological characteristics, providing detailed information regarding the basis for the determination of substantial equivalence.

- Risk Management

Risk management was performed in accordance with ISO 14971:2019. The design verification tests and their acceptance criteria were performed and identified as a result of this risk management.

## Substantial Equivalence

The DISPOSABLE BALLOON CATHETER B5-2Q, B7-2Q/2LA are substantially equivalent to the legally marketed predicate device based on the claim of substantial equivalence on similarities in intended use and technological features with the predicate device:

- similar intended use
- device characteristics (design, materials, and operations) are similar or identical to the predicate device, and
- does not introduce any new or novel treatments or standard of care that differs from predicate device in commercial use.

Due to a change in the manufacturer of Natural Rubber Latex (balloon material), the subject device will hold an increased amount (volume) of air in the balloon. Although this is different between Subject Device and Predicate Device, Olympus conducted Balloon Burst, Safety Verification, and Balloon Diameter measurements/testing to confirm device safety and effectiveness.

## Conclusion

In summary, the DISPOSABLE BALLOON CATHETER B5-2Q, B7-2Q/2LA is substantially equivalent to the predicate device and raises no new questions of safety or effectiveness.
