Intended Use

The Storz Modulith® Lithotripter Model SLK with Multiview option is intended for noninvasive fragmentation of urinary calculi in the kidney and upper ureter.

Device Description

The Storz Modulith® Lithotripter Model SLK with Multiview option is an extracorporeal pressure wave lithotripter. The Multiview option facilitates the additional display of up to two imaging systems on the Lithotrack® monitor.

AI/ML Overview

This looks like a 510(k) summary and FDA clearance letter for a medical device called the "Storz Modulith® Lithotripter Model SLK with Multiview option." This document asserts substantial equivalence to a predicate device rather than providing a detailed study demonstrating that the device meets specific acceptance criteria through performance data.

Therefore, most of the requested information regarding acceptance criteria, study details, sample sizes, ground truth, and expert involvement is not present in the provided text. This is typical for a 510(k) submission where the primary argument for clearance is substantial equivalence to an already legally marketed device, rather than novel clinical performance data.

Here's a breakdown of what can and cannot be answered based on the provided text:

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

  • Not Available. The document does not provide a table of acceptance criteria or reported device performance metrics tied to specific criteria. The clearance is based on substantial equivalence.

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

  • Not Applicable / Not Available. No specific test set data is provided for the "Storz Modulith® Lithotripter Model SLK with Multiview option" to demonstrate its performance against acceptance criteria. The clearance relies on the equivalence to a predicate device.

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 / Not Available. No ground truth establishment for a test set of the new device is discussed.

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

  • Not Applicable / Not Available. No test set or adjudication method is mentioned for the new device.

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

  • Not Applicable. This device is a lithotripter, which fragments urinary calculi. It is not an AI-assisted diagnostic imaging device, so an MRMC study with human readers improving with AI assistance would not be relevant.

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

  • Not Applicable. This device is a physical lithotripter, not an algorithm, so standalone algorithm performance is not relevant.

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

  • Not Applicable / Not Available. As no new performance study for the device is presented, no ground truth type for such a study is mentioned. The clearance is based on the previously established performance and safety of the predicate device.

8. The sample size for the training set

  • Not Applicable. This is a hardware device (lithotripter) and not a software algorithm that would require a training set.

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

  • Not Applicable. As per point 8, there is no training set for this type of device.

Summary based on the provided text:

The provided documents (510(k) Summary and FDA Clearance Letter) for the "Storz Modulith® Lithotripter Model SLK with Multiview option" do not describe a study to prove the device meets specific acceptance criteria through performance data. Instead, the clearance is based on a demonstration of substantial equivalence to an existing predicate device. The statement explicitly says: "The Storz Modulith® Lithotripter Model SLK with Multiview option for lithotripsy is substantially equivalent to the predicate device since the basic features and intended use are identical, and the design is similar. The minor differences between the Storz Modulith® Lithotripter Model SLK with Multiview option and the predicate device raises no new issues of safety and effectiveness, as these differences have no effect on the performance, function or intended use of these devices."

Therefore, the requested information pertaining to studies, sample sizes, ground truth establishment, and expert involvement for a new performance study is not applicable and not present in this type of submission.

§ 876.5990 Extracorporeal shock wave lithotripter.

(a)
Identification. An extracorporeal shock wave lithotripter is a device that focuses ultrasonic shock waves into the body to noninvasively fragment urinary calculi within the kidney or ureter. The primary components of the device are a shock wave generator, high voltage generator, control console, imaging/localization system, and patient table. Prior to treatment, the urinary stone is targeted using either an integral or stand-alone localization/imaging system. Shock waves are typically generated using electrostatic spark discharge (spark gap), electromagnetically repelled membranes, or piezoelectric crystal arrays, and focused onto the stone with either a specially designed reflector, dish, or acoustic lens. The shock waves are created under water within the shock wave generator, and are transferred to the patient's body using an appropriate acoustic interface. After the stone has been fragmented by the focused shock waves, the fragments pass out of the body with the patient's urine.(b)
Classification. Class II (special controls) (FDA guidance document: “Guidance for the Content of Premarket Notifications (510(k)'s) for Extracorporeal Shock Wave Lithotripters Indicated for the Fragmentation of Kidney and Ureteral Calculi.”)
