The summary describes a mechanical device (a stent) and its components, with no mention of software, algorithms, or any terms related to AI or ML.
Yes
The device is a ureteral stent used for drainage of urine from the kidney to the bladder, which is a therapeutic function.
No
The device is described as an indwelling ureteral catheter for drainage of urine, which is a therapeutic function, not a diagnostic one. It is designed to facilitate fluid flow, not to gather information for diagnosis.
No
The device description clearly outlines physical components like a flexible stent, insertion sheath, and pusher, indicating it is a hardware medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "as an indwelling ureteral catheter for drainage of urine from the kidney to the bladder." This describes a device used within the body for a therapeutic purpose (drainage), not for examining specimens outside the body to provide diagnostic information.
- Device Description: The description details a physical stent designed for insertion into the ureter. It doesn't mention any components or processes related to analyzing biological samples.
- Lack of IVD Indicators: There is no mention of:
- Analyzing biological specimens (blood, urine, tissue, etc.)
- Providing diagnostic information (identifying diseases, conditions, etc.)
- Reagents, calibrators, or controls typically associated with IVDs.
This device is a medical device, specifically a ureteral stent, used for a therapeutic intervention.
