Intended Use

The Medtronic AVE Bridge™ Stent System (Hi-Flex) -- Biliary Indication is intended to maintain patency of a biliary duct which is occluded by a malignant tumor.

Device Story

The Medtronic AVE Bridge™ Stent is a balloon-expandable intralumenal stent premounted on an over-the-wire PTA catheter. The device is used to maintain patency of bile ducts occluded by malignant tumors. It features radiopaque markers on the inner shaft at each end of the stent to facilitate placement under fluoroscopic guidance. The system is compatible with 0.035" guidewires. It is intended for use by physicians in a clinical setting. The device is provided sterile for single use. By expanding within the duct, the stent mechanically restores and maintains the lumen, potentially improving biliary drainage and patient symptoms associated with malignant obstruction.

Clinical Evidence

Bench testing only. Comparative performance testing was conducted between the subject and predicate devices, including balloon deflation time, crossing profile, stent free area, stent length, and stent recoil. Biocompatibility testing was performed with passing results.

Technological Characteristics

Balloon-expandable intralumenal stent; 316L stainless steel stent; PET PTA catheter; 5.3-5.8 F shaft diameter; 75-120 cm length; 0.035" guidewire compatibility; radiopaque markers; sterile; pyrogen-free; SAL 10^-6.

Indications for Use

Indicated for patients with biliary duct obstruction caused by a malignant tumor.

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

• Peripheral AVE Stent Delivery System (K983008)

System, Continued

| Performance<br>Testing | The subject device for this 510(k) is identical to the predicate device with the<br>exception of an alternate stent segment (component). The flexible Bridge™<br>Stent was found to be substantially equivalent in K983008 approved<br>November 25, 1998. Performance testing was conducted on the subject<br>device for the purpose of direct comparison to the predicate device. The<br>testing was chosen to highlight any differences between the subject device<br>and the predicate device. The balloon materials have not been changed. The<br>useable catheter length may be either 75 cm (cleared in K983008) or a new<br>length, 120 cm. The manufacturing process is not changed. | |

Dear Ms. Walton:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed prodicatc 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.
