Device Story

Pigtail Ureteral Catheter Sets and Sof-Flex® AQ® catheters facilitate urinary tract drainage, irrigation, and wire guide manipulation. Sets include polyurethane catheter (5-7 Fr) and PTFE-coated stainless steel wire guide; Sof-Flex® AQ® is a hydrophilic-coated polyurethane catheter (8.2-10 Fr). Distal ends feature pigtail loops with multiple sideports for fluid flow; proximal ends have polyamide female Luer lock adapters. Used by clinicians in clinical settings for urological procedures. Catheters provide access and drainage; wire guides assist in catheter placement or exchange. Radiopaque markers aid visualization. Devices are sterile, single-use, and intended to perform similarly to existing urological catheters, providing safe urinary tract access and fluid management.

Clinical Evidence

Bench testing only. Performance data included biocompatibility, sterilization, radiopacity, visual inspection, dimensional evaluation, wire guide compatibility, leakage, flow rate, kink radius, curl restoration, curl retention strength, tensile strength, and dynamic friction testing.

Technological Characteristics

Polyurethane catheter tubing; polyamide female Luer lock adapter; stainless steel wire guides with PTFE coating. Distal pigtail loop with sideports. Radiopaque. Sterilized via EtO (SAL 10^-6). Sizes: 5, 6, 7, 8.2, 10 Fr. Lengths: 56 cm or 70 cm.

Indications for Use

Indicated for drainage or irrigation in the urinary tract as well as access, advancement, or exchange of wire guides in patients requiring urological catheterization.

Regulatory Classification

#### Dear Chelsea Woods:

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 to 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. However, you are responsible to determine that the medical devices you use as components in the kit/tray have either been determined as substantially equivalent under the premarket notification process (Section 510(k) of the act), or were legally on the market prior to May 28, 1976, the enactment date of the Medical Device Amendments. Please note: If you purchase your device components in bulk (i.e., unfinished) and further process (e.g., sterilize) you must submit a new 510(k) before including these components in your kit/tray. 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.

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.

{1}------------------------------------------------

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 of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

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 https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

## Device Description:

The Pigtail Ureteral Catheter Sets consist of a catheter and wire guide. The catheters are constructed from polyurethane tubing and have a proximal female Luer lock adapter constructed from polyamide. The catheters are available in 5, 6, and 7 French (Fr) and a length of 70 centimeters (cm). The distal end of the catheter has a single pigtail loop with six sideports. The catheter has ink marks denoting depth and body orientation. The stainless steel wire guides are coated with polytetrafluoroethylene (PTFE) and available in diameters of 0.038 and 0.045 inches (in) with a length of 145 cm.

The Pigtail Ureteral Catheter Sof-Flex® AO® is a catheter with a hydrophilic coating. The catheters are constructed from polyurethane tubing and have a female Luer lock adapter constructed from polyamide. The catheters are available in 8.2 and 10 Fr and have a length of 56 cm. The distal end of the catheter has a single pigtail loop with 5 evenly spaced sideports around the pigtail loop. There are also 6 sideports spaced at 1 cm intervals just proximal to the pigtail loop on the same side of the catheter. For the next 10 cm after the sideports, on the straight portion of the catheter, there are no sideports. After which, there are 9 sideports placed at 1 cm intervals spiraled around the catheter across 8 cm.

The subject devices are provided sterile and are intended for one time use.

## Indications for Use:

Indicated for drainage or irrigation in the urinary tract as well as access, advancement or exchange of wire guides.

## Comparison to Predicate Device:

The subject devices have similar indications for use, methods of operation, and fundamental technological characteristics as the predicate device. Differences between the subject devices and the predicate device include a difference in indications for use, length, and coating.
