The KARL STORZ Urological Laser Accessories are used with laser fibers during urological endoscopic procedures.

Device Description

The KARL STORZ Urological Laser Accessories include Sheaths, Obturators, Working Elements, Guiding Probes, Telescope Bridge, Working Insert, and LUER-Lock Tube Connectors and Adaptor.

AI/ML Overview

This FDA 510(k) summary describes Karl Storz Urological Laser Accessories. Based on the provided text, there are no specific AI/ML components mentioned or evaluated through a study. Therefore, the questions related to AI/ML acceptance criteria, performance, and study design are not applicable.

The acceptance criteria and supporting studies focus on traditional medical device performance, biocompatibility, and reprocessing validation.

Here's a breakdown of the given information:

1. A table of acceptance criteria and the reported device performance

Acceptance Criteria CategorySpecific Criteria (Implicitly Met by Adherence to Standards)Reported Device Performance
BiocompatibilityCompliance with ISO 10993-1, -2, -5, -10, -11, -12, -18, -23Device complies with listed ISO 10993 standards, demonstrating biocompatibility.
Reprocessing ValidationCompliance with ISO 14937, ISO 17665-1, AAMI TIR 30:2011, ASTM F3208-17, ISO 15883-5Reprocessing data submitted complies with the listed standards, ensuring effective cleaning and sterilization.
Bench PerformanceDevice meets design specifications, substantial equivalence to predicate. These are tested through: - System Interlocking Test - Flow Test (comparative) - Bending Force TestAdditional bench testing was performed to ensure the device met its design specifications and is substantially equivalent to its predicate device. Specific quantitative results are not provided in this summary but the conclusion states they were met.
Technological CharacteristicsThe device's technological characteristics (dimensions, components, irrigation method) are compared to the predicate device to confirm substantial equivalence.Similar system components, continuous flow irrigation/aspiration. - Sheath: Diameter: 23.5-27.6Fr., Length: 216.5-239mm (Predicate: 21-24Fr., 235-260.5mm) - Obturator: Diameter: 19.9-21Fr., Length: 249.5-311.7mm (Predicate: 17.9-21.15Fr., 246.5-377.8mm) - Laser Guide Probe: Length: 342.7-345.7mm (Predicate: N/A) - Working Element: Diameter: 1x 4.4mm, 1x 2.5mm; Length: 2x 4.4mm (Predicate: N/A) - Telescope Bridge: Number of channels: 1 (Predicate: 1-2)

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Sample Size: Not explicitly stated as this is a non-clinical evaluation. The "sample size" would refer to the number of devices or components tested for biocompatibility, reprocessing, and bench performance. The summary only states that tests were performed.
  • Data Provenance: Not applicable in the context of clinical data. For non-clinical testing, it's generally conducted by the manufacturer or accredited labs, and the location is not specified in this summary. The studies are prospective in the sense that they are conducted specifically for regulatory submission, but they are not clinical studies on human subjects.

3. 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)

  • Not applicable. This device does not involve expert interpretation for ground truth establishment. Its performance is evaluated through objective, non-clinical tests based on established standards.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

  • Not applicable. This device does not involve human readers or interpretation of diagnostic images requiring adjudication.

5. 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, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This device is a surgical accessory, not an AI-powered diagnostic tool for human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

  • No, a standalone (algorithm only) performance evaluation was not done. This device is not an algorithm or AI system.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

  • The "ground truth" for this device's evaluation is defined by adherence to recognized international and industry standards for biocompatibility, reprocessing, and engineering design specifications. For example:
    • Biocompatibility: ISO 10993 series.
    • Reprocessing: ISO 14937, ISO 17665-1, AAMI TIR 30:2011, ASTM F3208-17, ISO 15883-5.
    • Bench Performance: Internal design specifications and comparative testing against the predicate.

8. The sample size for the training set

  • Not applicable. This device does not involve machine learning and therefore has no "training set."

9. How the ground truth for the training set was established

  • Not applicable. As there is no training set for an AI/ML algorithm, this question is not relevant.

Dear Emily Rhiel:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

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.

{1}------------------------------------------------

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); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatoryinformation/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

System Interlocking Test Flow Test (comparative) Bending Force Test
ClinicalPerformance Data:Clinical testing was not required to demonstrate the substantial equivalence to the predicate device. Non-clinical bench testing was sufficient to assess safety and effectiveness and to establish the substantial equivalence of the modifications.
Conclusion:The conclusions drawn from the non-clinical performance data demonstrated that the subject device is as safe as and as effective as the predicate device. As such, we concluded that the substantial equivalence of the subject and the predicate device has been met, and the differences between the subject and the predicate device do not raise new questions of safety and effectiveness.
