No
The summary describes a physical medical device (a ureteral stent) and its mechanical properties and performance. There is no mention of software, algorithms, image processing, AI, or ML.
Yes
The device is clearly indicated for promoting drainage of urine from the kidney to the bladder, which is a therapeutic function.
No
The device is described as an indwelling ureteral catheter designed to promote urine drainage, indicating a therapeutic or supportive function rather than a diagnostic one.
No
The device description clearly outlines physical components like a flexible stent, pusher, and suture, indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "promote drainage of urine from the kidney to the bladder." This is a therapeutic and mechanical function within the body, not a diagnostic test performed on samples outside the body.
- Device Description: The description details a physical stent and associated components used for insertion into the ureter. This aligns with a medical device used for treatment or support, not for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (like urine, blood, tissue, etc.), reagents, or any process related to diagnosing a condition based on in vitro testing.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. This device's function is purely mechanical and therapeutic.

Dear Ms. Kolb:
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.
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); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050.
