The AMSURE® HYDROPHILIC LATEX FOLEY CATHETER, is intended for use in the drainage of fluids from, and to the urinary tract/bladder.
The AMSURE Hydrophilic Latex Foley Catheter is a retention type urological catheter made of silicone coated natural Latex material modified with the addition of a lubricious/hydrophilic coating to facilitate the insertion of the catheter. It consists of a double lumen drainage tube with 2 opposing drainage eyes at the distal end. One lumen drains fluid to and from the urinary tract, while the second lumen is for inflation and deflation of the balloon. On the opposing end of the shaft are a connecting funnel and a luer activated valve. This product is available in a combination of French sizes, balloon capacities and lengths to accommodate pediatric and adult male and female applications. The device will be offered in French sizes from 12Fr to 28Fr, balloon size of 5 cc and 16-28 Fr in balloon size of 30cc. The device is disposable, sterile (Ethylene Oxide sterilization) and for single use only. The coating has been tested for its safety and efficacy.
The provided text is a 510(k) summary for the AMSURE® HYDROPHILIC LATEX FOLEY CATHETER, a medical device. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than conducting a full clinical trial or detailed performance study against specific acceptance criteria. Therefore, the document does not contain the detailed information requested regarding specific acceptance criteria, study designs, sample sizes, expert qualifications, or ground truth establishment for a standalone or MRMC study as would be present for software or AI-based devices.
However, based on the information provided, we can infer some aspects relevant to performance.
Acceptance Criteria and Device Performance
The core "acceptance criterion" for a 510(k) submission, especially a Special 510(k), is demonstrating that the device meets predetermined criteria through verification and validation activities and is substantially equivalent to predicate devices. This implies that the device's performance characteristics align with the established safety and effectiveness of the predicates.
| Acceptance Criteria (Inferred from Substantial Equivalence and Device Description) | Reported Device Performance (from K091699) |
|---|---|
| Material: Must be medically acceptable and suitable for intended use. | Latex: Device is made of silicone-coated natural Latex. This material is also used in at least one predicate (K030120, K040658). |
| Lumen Configuration: Must facilitate drainage and balloon inflation/deflation. | Dual Lumen: Device has a double lumen, similar to all listed predicate devices. One lumen for drainage, one for balloon. |
| Lubrication/Ease of Insertion: Must facilitate safe and comfortable insertion. | Lubricious/Hydrophilic Coating: "modified with the addition of a lubricious/hydrophilic coating to facilitate the insertion of the catheter." This is a key feature and a main difference from predicate K030120, but similar to K040658, K070508, and K984084. "The coating has been tested for its safety and efficacy." |
| Sterility: Must be sterile for single use. | Sterile (Ethylene Oxide sterilization): Device is sterile. This method differs from one predicate (Gamma for K030120) but is common for others. |
| Biocompatibility: Must be biocompatible with the human body. | Meet Requirements: "Biocompa-tibility Meet Requirements" for both the device on submission and all predicate devices. This implies standard biocompatibility testing was performed and passed. |
| Intended Use: Must align with the specified medical purpose. | Drainage of fluids from, and to the urinary tract/bladder: The intended use is identical to predicate K030120, K070508, and K984084. |
| Sizes and Capacities: Must accommodate intended patient population. | French sizes 12Fr to 28Fr, balloon size of 5 cc and 16-28 Fr in balloon size of 30cc: Available in a range to accommodate pediatric and adult male and female applications. This range is typical for Foley catheters and implicitly considered acceptable as part of substantial equivalence. |
| Performance (general): Must perform similarly to predicate devices. | Similar technological features and performance as the predicate device(s). "The device under submission having the same material, manufactured in the same manner and having a lubricious coat function have the same intended use as currently marketed devices raise no new issues of safety and effectiveness and are substantially equivalent." This is the overarching statement of performance demonstration for a 510(k), particularly a Special 510(k), where changes are being made to a previously cleared device. The "Declaration of Conformity" states that "all verification and validation activities were performed... and the results demonstrate that the predetermined criteria were met." This confirms internal testing validated the design. |
Detailed breakdown of study information:
-
A table of acceptance criteria and the reported device performance
- Please refer to the table above. The "acceptance criteria" for this type of submission are primarily implied by the demonstration of substantial equivalence to legally marketed devices and adherence to relevant standards for urological catheters, rather than specific numerical thresholds from a clinical trial. The "reported device performance" is the description of the device's characteristics and functions, and the claim that "all verification and validation activities were performed... and the results demonstrate that the predetermined criteria were met."
-
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- The document does not specify a clinical test set sample size or data provenance (country of origin, retrospective/prospective). This is a 510(k) submission for a Class II medical device, and it relies on bench testing and comparison to predicates for substantial equivalence, rather than a clinical trial with human subjects that often requires defined sample sizes and data provenance. The declaration states "all verification and validation activities were performed," implying laboratory/bench testing.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- This information is not provided and is not typically part of a 510(k) submission for this type of device. The "ground truth" for a physical device like a catheter is established through engineering specifications, material testing, biocompatibility studies, and performance testing against industry standards, not by expert consensus in the same way it would be for an AI diagnostic device.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set
- This information is not provided and not applicable. Adjudication methods like 2+1 or 3+1 are used in clinical trials or review processes where multiple experts evaluate ambiguous cases, often in diagnostic imaging or clinical outcomes. For a physical medical device, performance is typically measured through objective testing (e.g., tensile strength, flow rate, biocompatibility testing), not subjective adjudication.
-
If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No, an MRMC comparative effectiveness study was not done. This type of study is relevant for AI-powered diagnostic or assistive devices, which is not the case for this urological catheter.
-
If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- No, a standalone (algorithm only) performance study was not done. This concept is specific to software algorithms, particularly in diagnostics. The device is a physical catheter, not an algorithm.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- The "ground truth" for this device would be established through:
- Material specifications: Conformance to material standards (e.g., latex specifications).
- Biocompatibility testing: In-vitro and/or in-vivo tests showing non-toxicity and non-irritancy, following ISO 10993 series.
- Physical performance testing: Bench tests measuring parameters like balloon integrity, inflation/deflation time, flow rate, coating durability, tensile strength, and lubricity.
- Sterility assurance: Validation of the Ethylene Oxide sterilization process.
- These are technical and laboratory-based "ground truths" rather than clinical "ground truths" like pathology or outcomes data from human subjects in a trial for this type of submission.
- The "ground truth" for this device would be established through:
-
The sample size for the training set
- This information is not provided and not applicable. Training sets are used for machine learning algorithms. This device is a physical medical instrument, not an AI product.
-
How the ground truth for the training set was established
- This information is not provided and not applicable, as there is no training set for a machine learning algorithm.
