Indications for Use

The Peripheral AVE Biliary Stent System is intended for use in patients who are eligible for percutaneous transluminal angioplasty (PTA) to maintain patency of a biliary duct which is occluded by tumor. The Peripheral AVE Bilairy Stent System is indicated for palliative treatment of biliary duct strictures caused by malignant tumors.

Device Story

Balloon-expandable intraluminal 316L stainless steel stent; premounted on over-the-wire delivery catheter. Radiopaque platinum markers on inner shaft aid fluoroscopic placement. Used in biliary ducts; operated by physicians. Input: fluoroscopic visualization; Output: mechanical scaffolding of biliary duct. Stent expands via balloon inflation to maintain patency of ducts occluded by malignant tumors. Benefits: palliative treatment of strictures. Not for vascular use.

Clinical Evidence

Bench testing only. Studies compared minimum burst pressure, deflation times, two-plane crush strength, and dimensional uniformity against the predicate device. Results confirmed the subject device meets specifications and performs equivalently to the predicate.

Technological Characteristics

316L stainless steel balloon-expandable stent; diameters 6.0-10.0 mm; lengths 17-60 mm. Delivery system: PTA catheter, 5.3-5.8 F shaft, 75-90 cm length, 0.035" guidewire compatible. Radiopaque platinum markers. Radiation sterilization (ANSI/AAMI/ISO 11137-1994, Method I).

Indications for Use

Indicated for palliative treatment of biliary duct strictures caused by malignant tumors in patients eligible for percutaneous transluminal angioplasty (PTA).

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

• PALMAZ™ Balloon-Expandable Stent

#### Performance Testing:

Per 807.92(b)(1) If the determination of substantial equivalence is also based on an assessment of performance data, the summary includes a brief discussion of the non clinical tests and how their results support a determination of substantial equivalence

#### 1. Peripheral AVE Biliary Stent System vs JJIS Palmaz™ Balloon-Expandable Stent - Balloon Performance Study

#### Purpose:

To compare the minimum burst pressure and deflation times of the Peripheral AVE Biliary Stent System balloons to the PALMAZ™ Balloon-Expandable Stent balloons. The data gathered will support a premarket notification for the Peripheral AVE Biliary Stent System.

#### Results:

The test proved substantial equivalence.

#### 2. Peripheral AVE Biliary Stent System vs JJIS Palmaz™ Balloon-Expandable Stent - Two Plane Crush Strength Study

#### Purpose:

To determine and compare the radial strengths of the Peripheral AVE Biliary Stent and the PALMAZ™ Balloon-Expandable Stent by graphically representing the amount of force required to crush a stent to fifty percent (50%) of its deployed diameter. The data gathered will support a premarket notification for the Peripheral AVE Biliary Stent System.

#### Results:

The test proved substantial equivalence.

## 3. Peripheral AVE Biliary Stent Dimensional Verification and Stent Uniformity at Nominal Deployment

#### Purpose:

To verify that processed Peripheral AVE Biliary Stents meet diameter and length specifications after deployment. The data gathered will support a premarket notification for the Peripheral AVE Biliary Stent System.

#### Results:

The results conclude that the stents tested meet the labeled specifications for stent diameter and stent length.

{6}------------------------------------------------

# CONCLUSIONS:

The Peripheral AVE Biliary Stent vs the JJIS Palmaz™ Balloon-Expandable Stent performance testing results prove that the Peripheral AVE Biliary Stent is substantially equivalent to the JJIS Palmaz™ Balloon-Expandable Stent

Dear Mr. Mever:

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 predicte 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.

Page 2 - Mr. Paul A. Meyer

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

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 510(k) premarket notification if the limitation statement above is added to your labeling, as described.

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.

If you desire specific information about the application of other labeling requirements to your device (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone].
