The description focuses on the material, design modifications (anchorage profile, wire form), manufacturing process, and sterilization of a physical ureteral stent. There is no mention of software, algorithms, data processing, or any terms related to AI or ML.
Yes.
The device facilitates drainage from the kidney to the bladder and provides stenting of the ureter, which directly treats or alleviates a medical condition.
No.
The device is a ureteral stent used for facilitating drainage and providing structural support, not for diagnosing conditions.
No
The device is a physical ureteral stent made of hydrogel and metal, designed for implantation. It is not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions.
- Device Description and Intended Use: The description clearly states that the pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent is an implanted device used to facilitate drainage and stenting within the ureter. It is a physical device inserted into the body, not a test performed on a sample outside the body.
- Lack of IVD Characteristics: The text does not mention any analysis of biological samples, detection of analytes, or diagnostic purposes based on laboratory testing.
Therefore, this device falls under the category of an implanted medical device, specifically a ureteral stent, and not an in vitro diagnostic.

Device Description
The pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent meets the statutory definition of 21 CFR 876.4620 as a "tube-like", implanted device that is inserted into the ureter to provide ureteral rigidity and allow the passage of urine. Ureteral stents may have finger-like protrusions or hooked ends to keep the tube in place. They are used in the treatment of ureteral injuries and ureteral obstruction.
The purpose of this Special 510(k) is to expand the product line of the pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent [510(k) K163068], to add variations in anchorage profile. The recommended usage of the pAguaMedicina™ PERSISTENTTM Structural Hydrogel Ureteral Stent, to facilitate drainage from the kidney to the bladder and stenting of the ureter in patients not less than 2 years old, remains unchanged.
Particular uses and the choice of anchorage profile are left to the physician's discretion and suggestions do not appear in the labeling. The labeling will only identify the type of anchorage profile. All stents are radiopaque. All stents by Q Urological TM Corporation are single use, sterile devices, administrated in healthcare facilities by prescription.
As with the cleared / predicate pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent, the modified stent may be placed using endoscopic, percutaneous, or 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 proposed stents will be made of the same material as the predicate (trademark paguamedicina™), a partiality hydrolyzed polyacrylonitrile, produced in part from a proprietary manufacturing process.
The modified device incorporates a wire form which creates a pigtail configuration upon deployment. The wire is composed of metals that have been implanted in the human body in a wide variety of locations (tissue and bone), for numerous applications and are considered to be biocompatible.
The manufacturing methods, process parameters, design controls and quality assurance system (QSR - 21 CFR 820) used for all pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stents are the same as those of the cleared / predicate device; [510(k) K163068].

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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 modified anchorage configurations do not introduce any different questions of safety and effectiveness from the predicate / cleared product [510(k) K163068].

The stents are sterilized by E Beam radiation to a sterility assurance level of 10-6.
LEGALLY MARKETED DEVICE: The Subject of this Special 510(k) is being compared for substantially equivalence to the pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent, a legally marketed device, as originally cleared in 510(k) K163068.
SUMMARY STATEMENT:
This Special Premarket Notification proposes to expand the product line of pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stents by adding additional anchorage profiles, providing the physician the ability to select the most appropriate product for the individual patient.
Clearance of the proposed modification, which creates stents with a pigtail loop, will allow for the addition of two new devices, extending the available product offering. In one configuration, the currently cleared bulbous anchorage will be used in the bladder and the proposed pigtail anchorage in the kidney (bulbous / pigtail). In a second device, both ends of the stent will utilized the proposed pigtail anchorage (pigtail / pigtail). Both products will be available in the same sizes and lengths as the unmodified product.
The labeling of the entire product line is consistent with that of the cleared / predicate device as it displays 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 Resterilization and Prescription Legend. The appropriate labeling components of the modified products will be revised to reflect the particular anchorage profile.
Development of the modification of the pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent was done in accordance with 21 CFR 820.30. Compliance with other aspects of the Quality Systems Regulation (21 CFR 820) was maintained as appropriate. Regardless of anchorage profile, the stents are made from the same raw material (paguamedicina™). 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 modified anchorage configurations do not introduce any different questions of safety and effectiveness from the predicate / cleared product [510(k) K163068].
SUBSTANTIAL EQUIVALENCE: The proposed stents have the same intended use and indication for use as the predicate / cleared, pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stent.
Q Urological Corporation / 93 West Street. / Suite C1 / Medfield, MA. 02052 / 508 728 1031
6
The information included in this 510(k) demonstrates that any differences in the technological characteristics of stents with pigtail shaped anchorage do not raise different questions of safety and effectiveness from the predicate / cleared stent. Therefore, the proposed stents are as safe and effective as the predicate / cleared device and can be considered substantially equivalent to the pAguaMedicina™ PERSISTENT™ Structural Hydrogel Ureteral Stents cleared under 510(k) K163068.
