Dear Lucius Long:

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.

Following insufflation, the balloon surface lies flat against the bile duct wall, enabling efficient and complete cleaning of the bile duct. A separate lumen is designed for a 0.035 inch guidewire. Another separate lumen is designed for contrast agent.

The balloon can be inflated to $8.5 \mathrm{~mm}$ , $12 \mathrm{~mm}$ , $15 \mathrm{~mm}$ and $18 \mathrm{~mm}$ diameters using the inflation pump and be kept in an inflated state by two-way valve. Balloon can be inflated to two or three distinct sizes if a different diameter is needed without having to exchange devices. During stone removal process, the balloon can be filled to removal multiple stones in the biliary tract.

There are two developing rings placed at the distal and proximal ends of the balloon providing high fluoroscopic visualization of the balloon location.
