The document describes a physical medical device (a ureteral stent) and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML.
Yes.
The device facilitates drainage and stenting of the ureter and is used in the treatment of ureteral injuries and ureteral obstruction, which are therapeutic actions.
No
This device is a ureteral stent designed to facilitate drainage and provide structural support for the ureter, which is a therapeutic function, not a diagnostic one.
No
The device description clearly states it is a "fube-like implanted device" and a "tube," indicating it is a physical, hardware-based medical device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to facilitate drainage and stenting within the ureter, which is an internal bodily structure. IVDs are used to examine specimens derived from the human body (like blood, urine, or tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.
- Device Description: The device is described as an implanted device inserted into the ureter. This is an in vivo application, not an in vitro test.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any of the typical components or processes associated with IVD devices.
Therefore, the pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent is a medical device used in vivo for a therapeutic purpose, not an IVD.
N/A

Device Description
The pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent is a "tube-like implanted device that is inserted into the ureter to provide ureteral rigidity and allow the passage of urine. The device may have finger-like protrusions or hooked ends to keep the tube in place. It is used in the treatment of ureteral injuries and ureteral obstruction" (21 CFR 876.4620).
The purpose of this Special 510(k) is to expand the product line of a 4 French ureteral stent [510(k) K082805] to add stents in sizes 5, 6, 7 and 8 French. The recommended usage of the pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent is to facilitate temporary internal urinary drainage between the bladder and kidney and stenting of the ureter, in patients of no less than 2 years of age.
Particular uses and the choice of size are left to the physician's discretion and suggestions do not appear in the labeling. All stents by Q Urological™ Corporation, are single use, sterile devices, administrated in healthcare facilities by prescription.
As with the cleared / predicate 4 French device, the 5, 6, 7 and 8 French pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent may be placed endoscopically, percutaneously, or using open surgical techniques. The stent should not be implanted for more than 30 days. The product is not intended as a permanent indwelling device.
The larger sized 5, 6, 7 and 8 French stents will be made of the same raw material as the 4 French stents (trademark pAguaMedicina™ (polyaguamedicina)), a partially hydrolyzed polyacrylonitrile, produced in part from a proprietary manufacturing process.
The manufacturing methods, process parameters, design controls and quality assurance system (QSR – 21 CFR 820) used for all sizes of the pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent are the same; [510(k) K082805] the cleared / predicate device. Technological characteristics, including composition and radiopacifier of the modified (larger size) stent are also the same as those of the cleared device (the 4 French, Q Urological™ Corporation pAguaMedicina™ Structural Hydrogel Pediatric Ureteral Stent).
The stents are sterilized by E Beam radiation to a sterility assurance level of 10-9.

The device may have finger-like protrusions or hooked ends to keep the tube in place. It is used in the treatment of ureteral injuries and ureteral obstruction" (21 CFR 876.4620).
The purpose of this Special 510(k) is to expand the product line of a 4 French ureteral stent [510(k) K082805] to add stents in sizes 5. 6. 7 and 8 French. The recommended usage of the pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent is to facilitate temporary internal urinary drainage between the bladder and kidney and stenting of the ureter, in patients of no less than 2 years of age.
Particular uses and the choice of size are left to the physician's discretion and suggestions do not appear in the labeling. All stents by Q Urological™ Corporation, are single use, sterile devices, administrated in healthcare facilities by prescription
As with the cleared / predicate 4 French device, the 5, 6, 7 and 8 French pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent may be placed endoscopically, percutaneously, or using open surgical techniques. The stent should not be implanted for more than 30 days. The product is not intended as a permanent indwelling device.
The larger sized 5, 6, 7 and 8 French stents will be made of the same raw material as the 4 French stents (trademark pAguaMedicina™ (polyaguamedicina)), a partially hydrolyzed polyacrylonitrile, produced in part from a proprietary manufacturing process.

Technological characteristics, including composition and radiopacifier of the modified (larger size) stent are also the same as those of the cleared device (the 4 French, O Urological™ Corporation pAguaMedicina™ Structural Hydrogel Pediatric Ureteral Stent).
The stents are sterilized by E Beam radiation to a sterility assurance level of 10-9.
LEGALLY MARKETED DEVICE:
The subject of this Special 510(k) is being compared for substantially equivalence to the 4 French. O Urological™ Corporation pAguaMedicina™ Structural Hydrogel Pediatric Ureteral Stent, as originally cleared in 510(k) K082805, on January 20, 2010.
SUMMARY STATEMENT:
5
This Special Premarket Notification proposes to extend the product line of the Q Urological™ Corporation pAguaMedicina™ Structural Hydrogel Pediatric Ureteral Stent by adding additional sizes. The word "PERSISTENT" is being added to the trade name and the term "pediatric" removed.
It is proposed that 5. 6. 7 and 8 French stents be added to the currently cleared 4 French (predicate) offering in order to give the physician the ability to select the most appropriate product for the individual patient. The 6, 7 and 8 French stents will be available in a variety of longer lengths. The possible lengths for the 5 French stent will be the same as those of the currently (cleared / predicate) 4 French stent. Appropriate labeling components will be revised to reflect the particular French and length.
The labeling of the entire product line (4, 5, 6, 7 and 8 French) is consistent with that of the cleared / predicate device as it bears the same insertion, retrieval / removal or exchange procedure; sterility method; stability / expiration dating; and labeled Contraindications, essential Warnings and Precautions. Complications, Single Use Designation, Limitation on Reuse and Re-sterilization and Prescription Legend.
Development of the 5, 6, 7 and 8 French stents was done in accordance with 21 CFR 820.30. Compliance with other aspects of Quality Systems Regulation (21 CFR 820) was maintained as appropriate. All sized stents are made from the same raw material and the same radiopacifier is used. The manufacturing methods, process parameters, design controls and quality assurance system are also the same. The stents are sterilized by E Beam radiation to a sterility assurance level of 10-6.
No non-clinical or clinical performance data are included in this Special 510(k). Substantial Equivalence was established under Design Controls by validation and verification activities performed to reflect findings of individual risk analysis.
These verification and validation activities found that any differences in the values of attributes for the larger stents were proportional to those of the cleared / predicate 4 French stent [510(k) K082805].
SUBSTANTIAL EQUIVALENCE:
The proposed stents in sizes 5, 6, 7 and 8 French have the same intended use and indication for use as the cleared / predicate 4 French ureteral stent with the exception of the removal of an upper age limit of 12. This was done because no correlation between the appropriate size stent and age has been established. Selection of the proper size stent is the responsibility of the physician.
"PERSISTENT" is being added to the name of the product line and the word "pediatric" will be removed. The cleared / predicate 4 French stent will remain in the product line
