## Indications for Use

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

## Device Story

Formula 418 Biliary Stent is a balloon-expandable, stainless steel stent premounted on a delivery system. Intended for one-time use in the biliary tree to palliate malignant neoplasms. Device is supplied sterile. Physician operates the delivery system to place the stent. Output is the physical stent structure providing biliary patency. Benefits include relief of biliary obstruction caused by malignancy.

## Clinical Evidence

Bench testing only. Testing included deployment, compression force, expansion force, dimensional, corrosion, balloon performance, stent deformation, tensile strength, MRI compatibility, shelf life, and biocompatibility testing.

## Technological Characteristics

Balloon-expandable stainless steel stent. Available in diameters 3-8 mm and lengths 12-30 mm. Premounted on delivery system. Sterile, single-use. No software or electronic components.

## Regulatory 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.

#### Device:

| Trade Name:              | Formula 418 Biliary Stent        |
|--------------------------|----------------------------------|
| Proposed Classification: | Biliary Catheter and Accessories |

#### Indications for Use

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

## Predicate Devices:

The Formula 418 Biliary Stent is similar in terms of intended use, principles of operation, materials of construction and technological characteristics to predicate devices reviewed as devices for palliation of malignant neoplasms in the biliary tree.

## Device Description:

The Formula 418 Biliary Stent is a balloon-expandable, stainless steel stent which is premounted on the delivery system. The stent will be available in diameters of 3, 4, 5, 6, 7, and 8 mm and lengths of 12, 16, 20, 24 and 30 mm. This device will be supplied sterile and is intended for one-time use.

## Substantial Equivalence:

The Formula 418 Biliary Stent is similar to many devices in commercial distribution for palliation of malignant neoplasms in the Biliary tree. These devices include the Bridge FX (Bridge Assurant) Stent Delivery System (D.C. #K011817) stent, the Palmaz Genesis Transhepatic Biliary Stent (D.C. #K021345) and the Lifestent LP SDS Biliary Endoprosthesis (D.C.#K023248).

The similar indications for use, principles of operation, technological characteristics and performance testing results of the Formula 418 Biliary Stent

as compared to the predicate devices support a determination of substantial equivalency.

# Test Data:

The Formula 418 Biliary Stent was subjected to the following tests to assure reliable design and performance under the specified testing parameters. These tests were comprised of:

- Deployment Testing 1.
- Compression force Testing 2.
- Expansion Force Testing 3.
- Dimensional Testing 4.
- 5. Corrosion Testing
- Balloon Performance Testing 6.
- Stent Deformation Testing 7.
- Tensile Strength Testing 8.
- ்ல Magnetic Resonance Imaging (MRI) Testing
- Shelf Life Testing 10.
- 11. Biocompatibility Testing

The results of these tests provide reasonable assurance that the device has been designed and tested to assure conformance to the requirements for its use as a biliary stent.

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.
