Used by clinicians in clinical settings for percutaneous biliary drainage via over-the-wire technique. Catheter position established; pigtail formed by retracting internal suture; hub locks suture to maintain shape. Repositioning tool allows unlocking for adjustment or replacement. Printed shaft markings assist depth assessment. Device facilitates bile flow, relieving biliary obstruction. Supplied sterile, single-use.

Clinical Evidence

Bench testing only. No clinical data provided. Performance testing included cyclic fatigue, tensile testing, flow testing, kink testing, tip penetration, hub leak/ingress, guide wire passage, and hydrophilic coating adherence. Biocompatibility testing included cytotoxicity, sensitization, irritation, acute systemic toxicity, pyrogenicity, genotoxicity, and implantation per USP standards.

Technological Characteristics

Single-lumen polyurethane catheter; 8.5F-14F sizes; 40cm length. Features hydrophilic coating, locking pigtail mechanism, and radiopaque marker band. Includes metal/flexible stiffening cannulas, pigtail straightener, and repositioning tool. Sterilized, single-use. Complies with USP <151> (pyrogen) and USP <661> (plastics).

Indications for Use

Indicated for patients requiring biliary drainage within the biliary system.

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.

{4}------------------------------------------------

The ReSolve® Biliary Locking Drainage Catheter consists of single lumen tubing with 17 to 18 drainage holes (depending on the French size of the catheter) and a single dedicated suture hole. One of the drainage holes doubles as a suture hole. The tubing is made from a polyurethane material. A hydrophilic coating reduces entry site/catheter friction during placement. The catheter is offered in two drainage hole configurations. The RBC (long) configuration has a lesion gap (distance between the proximal pigtail and the distal shaft drainage hole) of 5 cm. The RBDC (standard) has a lesion gap of 2 cm. The components of the catheter allow initial placement using an over-the-wire technique. These include a metal stiffening cannula, flexible stiffening cannula, pigtail straightener and repositioning tool. The hubs of the flexible and metal stiffening cannula are color coded for catheter French size identification. The pigtail straightener is provided to assist in feeding the guide wire through the catheter. A dead end cap is included to prevent fluid from exiting the catheter after placement. Once the catheter position is established in the area to be drained, the Device Description pigtail is formed by retracting a suture which is looped from the hub to catheter tip then back to the hub. The hub incorporates a suture locking mechanism to retain the distal pigtail shape. It may be unlocked using the repositioning tool to allow repositioning or replacement of the catheter. A single radiopaque marker band is located proximal to the most proximal drainage hole to assist in accurate placement of the drainage holes in the biliary duct. In addition, the shaft of the catheter is printed with markings for the clinician to determine how deep the catheter is in the patient. The catheter is available in the same sizes 8.5F, 10F, 12F, and 14F with the same useable length, 40 cm, as the predicate device. The ReSolve® Biliary Locking Drainage Catheter is a single use device that is supplied sterile and non-pyrogenic. The device is marketed with the following components, depending on the product configuration: StayFIX® or Revolution™ catheter securement device.

{5}------------------------------------------------

| | The technological characteristics of the subject ReSolve® Biliary<br>Locking Drainage Catheter are substantially equivalent to those<br>of the predicate device. The subject device has the same basic<br>design as the predicate device in that it consists of single lumen<br>tubing with drainage holes, hub, and suture locking mechanism<br>and is provided with a metal stiffening cannula, flexible stiffening<br>cannula, pigtail straightener, repositioning tool and dead end<br>cap. The ReSolve® Biliary Locking Drainage Catheter is similar<br>in clinical use and function to the predicate ReSolve® Biliary<br>Locking Drainage Catheter. |
|-----------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Comparison to<br>Predicate Device | The main difference is in the catheter shaft material and that the<br>subject device is coated with a different hydrophilic coating on<br>the outer surface of the catheter tubing. In addition, printed<br>depth markings have been added to the catheter shaft and the<br>location of the drainage holes has been modified to standardize<br>the gap between the pigtail and the shaft holes (RBC versus<br>RBDC) across all French sizes with adjustment of the marker<br>band location to account for this change. The geometry of the<br>tip has been modified slightly to have a longer taper. |
| | Minor changes have also been made to the colorant formulation<br>(color additives) used in molding three of the accessory<br>components of the device due to discontinuation notices from<br>suppliers. |
