The device description and performance studies focus on the physical properties and functionality of a ureteral stent, with no mention of AI or ML.
Yes
The device is intended for temporary internal drainage and to relieve obstruction in various conditions, which are therapeutic interventions.
No
The device, a ureteral stent, is intended for "temporary internal drainage" to "relieve obstruction," which are therapeutic rather than diagnostic functions.
No
The device description clearly details a physical, implantable medical device made of polyurethane material, including various hardware components like a pigtail straightener, stent positioner, and wire guide. There is no mention of software as a component or the primary function of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "temporary internal drainage from the ureteropelvic junction to the bladder." This describes a therapeutic intervention within the body, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details a physical device (a stent) designed to be implanted in the urinary tract. It does not describe reagents, instruments, or systems used to examine specimens.
- Performance Studies: The performance studies listed (Sterility, Packaging, Biocompatibility, etc.) are typical for implanted medical devices, not for diagnostic tests.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting analytes, or providing diagnostic information.
In summary, the Universa® Firm Ureteral Stent Sets are a medical device used for drainage, which is a therapeutic function, not a diagnostic one.

Device Description
The Universa® Firm Ureteral Stents and Stent Sets are sterile, single-use devices. The stents are available in 5.0 to 8.0 French (Fr) diameter, with lengths ranging from 18.0 to 32.0 centimeters (cm). The stents are constructed of radiopaque polycarbonate-based polyurethane material and include a hydrophilic coating. Sideports extend along the body of the stent as well as on the pigtails to provide drainage. The stents are secured in the urinary tract with pigtail loops on the proximal and distal ends. A braided or monofilament tether for repositioning and removal of the device is located on the proximal pigtail (bladder end) of the stent. Along the stent are graduation marks to provide visualization during stent advancement and placement. The Universa® Firm Ureteral Stent includes a pigtail straightener, a small polymer tube to aid in placement over a wire guide. The pigtail straightener is removed prior to use. The stent and pigtail straightener can be sold as a set with a stent positioner and stainless steel wire guide. The positioner and the wire guide are available for sale separately. The Universa Firm Ureteral Stents and Stent Sets are labeled for a 12-month indwell time; however, the tether should be removed after 14 days.

Dear Jamie Ridner,
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. 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.
