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.

Predicate Devices

• Absolute® 035 Biliary Self-Expanding Stent System (K033393)

## Summary of Substantial Equivalence:

The Absolute® Pro .035 Biliary Self-Expanding Stent System is substantially equivalent to the Absolute® 035 Biliary Self-Expanding Stent System (K033393, cleared 11/10/03); and Xceed Nitinol Self Expanding Transhepatic Biliary Stent System (K050501, cleared 3/14/05).

## Device Description:

The Absolute® Pro .035 Biliary Self-Expanding Stent System includes a selfexpanding nickel titanium stent that is pre-mounted on an over-the-wire Delivery System. A total of 12 (6 at each end) radiopaque markers made of a radiopaque nickel titanium alloy are located at the ends of the stent. The Absolute Pro .035 Biliary Self-Expanding Stent System utilizes a 0.035" (0.89 mm) guide wire. The system includes radiopaque markers that identify the stent location.

The catheter comprises a retractable sheath that covers the stent during delivery. a radiopaque tip, an I-Beam to support the stent during deployment with an internal guide wire lumen, a detachable outer jacket, and a handle assembly with a safety lock and retraction features. With the handle in the unlocked position, rolling back the thumbwheel deploys the stent.

Dear Ms. Grossman:

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.

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.

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.
