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.

TRADITIONAL 510(K) NOTIFICATION SINGLE USE CYTOLOGY BRUSH V BC-V600P-3010

## Indications for Use

The Single Use Cytology Brush V BC-V600P-3010 is intended to be used to collect tissue specimens in the biliary system in combination with an endoscope.

## Device Description

BC-V600P-3010 has been designed to collect specimens or cells endoscopically for cytologic examination in conjunction with duodenoscopes. BC-V600P-3010 is inserted into the duodenoscope through an instrument channel to reach the target area, where, by rubbing the brush on the target area, specimens or cells can be collected. BC-V600P-3010 is then withdrawn from the duodenoscope channel with the collected samples.

The handle is connected to operating wires. The grip on the handle portion controls the brush movement inside the tube. By pushing/pulling the handle, the brush at the distal end of the Subject device can be protruded from/drawn into the tube. Cells can be collected by moving over the target site with the brush.

The BC-V600P-3010 consists of:

A. Handle

- Grip: used to push to extend the brush from the tube. Pull to retract the brush back into the tube.
- Operation pipe: used to connect the grip with the wires so that it can transfer the force to push/pull the brush/distal tip.
- Locking cap: used for fixing the location of the brush by turning the locking cap clockwise.
- Injection port: Available to attach a syringe here to inject contract medium.
- Hook: attached to the boot of the endoscope or ET Control Device V (sold separately).

B. Insertion portion

- Wires: connect operation pipe with brush and distal tip to push/pull the brush from/into the tube
- Tube: works as the channel that the contrast media is injected through during use
- V marking: gives the user an approximate indication of how far the instrument has been inserted into the endoscope,
- Radiopaque marks: allow the distal end of the tube to be visualized on the X-ray monitor
- Brush: used to brush the target area to collect samples.
- Distal tip: When using a guidewire, the guidewire is inserted into the distal tip.

| Basic principle | The SD is inserted into the duodenoscope through an instrument channel to reach the target area, where, by rubbing the brush on the target area, specimens or cells can be collected. The SD is then withdrawn from the duodenoscope channel with the collected samples. | The Fusion Cytology Brush is used by passing the device through an endoscope over a prepositioned wire guide to a target location.The cytology brush is located at the distal end (patient contacting) of the device with the pin vise handle located at the proximal end (non-patient contacting). The handle is actuated by pushing the pin vise handle forward to extend the cytology brush and then pulling backward to retract the brush. |

| Feature / Characteristic | Subject Device (SD) | Predicate Device (PD) |

| Sterilization Method | EO | EO |

The Single Use Cytology Brush V BC-V600P-3010 is substantially equivalent to the legally marketed predicate device based on the claim of substantial equivalence on similarities in technological features with the predicate device:

- same 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.

The guidewire is inserted into the distal tip of the Subject Device, as opposed to the handle section of the Predicate Device. As a result, the tip shape design of the Subject Device has been changed to accommodate the insertion of the guidewire. There is no difference in the purpose and the directions for use of a guidewire, other than the method of insertion.

The brush length and number of bristles is different between the SD and the PD to meet design requirements for insertion/withdrawal forces of the SD into/from compatible endoscopes. This does not change the purpose or direction of the device.

The subject device has an added hook, locking cap and injection port that are not found on the subject device. These features were added for customer ease of use and do not change the purpose or direction of the device.

## Summary of Performance Testing

The following performance testing was conducted in support of substantial equivalence determination.

## Biocompatibility Testing

Biocompatibility testing was conducted in accordance with the FDA's Guidance for Industry and Food and Drug Administration Staff, Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". The biocompatibility testing included the following tests:

- Cytotoxicity Study using the ISO Elution method (ISO 10993-5)
- Intracutaneous Irritation Study (ISO 10993-23)
- Guinea Pig Maximization Sensitization Test (ISO 10993-10)
- Material-mediated Pyrogen Testing (USP, <151>)
- Acute Systemic Toxicity Study in Mice (ISO 10993-11)

- Animal Testing

Olympus conducted animal testing to verify that the Subject Device’s dimensions are effective to perform as a cytology brush used to collect cells in the biliary system.

In the animal test, the brush was inserted into a living pig's bile duct, scraped, and the collected samples were compared with the Predicate Device's samples to determine sufficient quantity and quality for cytology.

## Conclusion

In summary, the Single Use Cytology Brush V BC-V600P-3010 is substantially equivalent to the predicate device.
