Intended Use

The Express LD Biliary Premounted Stent System is indicated for the palliation of malignant neoplasms in the biliary tree.

Device Story

The Express LD Biliary Premounted Stent System is a balloon-expandable stent used for biliary palliation. The device consists of a 316L surgical grade stainless steel stent premounted on an over-the-wire delivery system (SDS) featuring a non-compliant balloon. The SDS includes two radiopaque markers for placement guidance and is compatible with 0.035-inch guidewires. The system is used by clinicians in a clinical setting to treat malignant biliary obstructions. The physician navigates the delivery system to the target site, inflates the balloon to expand the stent, and then deflates the balloon for removal. The stent remains in the biliary tree to maintain patency, providing symptomatic relief for patients with malignant neoplasms. The device is not indicated for vascular use.

Clinical Evidence

Bench testing only. Testing included balloon deflation time, guidewire compatibility, multiple balloon inflations, rated burst pressure, radiopaque marker location, MEM elution cytotoxicity, hemocompatibility (direct hemolysis), and USP physicochemical testing. No clinical data provided.

Technological Characteristics

316L surgical grade stainless steel balloon-expandable stent; non-compliant balloon; over-the-wire delivery system; radiopaque markers; compatible with 0.035 in guidewires; max inflation pressure 12 atm; EO sterilization.

Indications for Use

Indicated for palliation of malignant neoplasms in the biliary tree. Prescription use only.

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 Device Express LD Biliary Premounted Stent System

#### Device Description

The Express LD Biliary Premounted Stent System consists of: A 316L surgical grade stainless steel balloon expandable stent. The stent is premounted on an over the wire Stent Delivery System (SDS) equipped with a non-compliant balloon. The SDS balloon catheter has two radiopaque markers embedded in the shaft to aid in the placement of the stent. The SDS is compatible with 0.035 in (0.89 mm) guidewires. The SDS balloon has a maximum inflation pressure of 12 atm (1216 kPa) that can be used for initial stent placement and post stent dilatation. The Premounted Stent System is available in a variety of stent lengths with SDS balloons that expand them from 5 mm to 10 mm in diameter. The SDS balloon catheter is also offered in two shaft lengths.

#### Indications for Use

The Express LD Biliary Premounted Stent System is indicated for the palliation of malignant neoplasms in the biliary tree.

#### Substantial Equivalence

The proposed Express LD Biliary Premounted Stent System is substantially equivalent to the predicate Express LD Biliary Premounted Stent System which was cleared by FDA under premarket notification K021630 (October 25, 2002). The proposed Express LD Biliary Premounted Stent System has the same intended use and device performance as the predicates Express LD Biliary Premounted Stent System (K021630, K024048, and K032360),

Dear Rence Mitchell.

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 10 devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (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 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. 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.

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.

Image /page/3/Picture/11 description: The image shows the logo for the U.S. Department of Health & Human Services. The logo consists of a circle with the text "DEPARTMENT OF HEALTH & HUMAN SERVICES USA" around the perimeter. Inside the circle is a stylized symbol that resembles a bird or a person with outstretched arms. The symbol is made up of three curved lines that are stacked on top of each other.

#### Page 2 - Renee Mitchell

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.

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.

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.

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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807): labeling (21 CFR Part 801) medical device reporting (reporting of medical devicerelated adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801) please contact the Division of Small Manufacturers, International and Consumer Assistance at its tollfree number [phone] or [phone] or at its Internet address http://www.fda.gov/MedicalDevices/ResourcesforYou/Industry/default.htm. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to
