    Intended Use

    The Electrohydraulic Lithotriptor is intended to be used with Potent Medical disposable electrohydraulic lithotripsy (EHL) probes for disintegration of concernments in the bile duct.

    Device Description

    The EHL is a compact, table-top medical device designed for the fragmentation of biliary calculi. It operates by generating high-voltage electric pulses, which are transmitted through a compatible disposable EHL probe (sold separately) that is inserted into the biliary tract via an endoscope. The device features two operational modes: single pulse and continuous pulse. These electric pulses create hydraulic shock waves in a saline medium, causing fragmentation of biliary stones into smaller pieces that can either be naturally passed or removed endoscopically.

    AI/ML Overview

    I am sorry, but based on the provided text, there is no information about acceptance criteria or a study that specifically proves the device meets such criteria.

    The document is a 510(k) summary for an Electrohydraulic Lithotriptor (TCS-B3-II) and focuses on demonstrating substantial equivalence to a predicate device (EL27-Compact). It outlines various performance and safety tests conducted but does not provide specific acceptance criteria values or detailed study results in the format requested.

    The "Performance Data" section mentions "Stone Fragmentation Test," "Shockwave Pressure Attenuation Test," "Acoustic Characterization Test," "Electrical Safety and Electromagnetic Compatibility (EMC) Testing," and "Software Verification and Validation." However, it only describes what these tests validated or complied with (e.g., "validated the system's ability to generate consistent high-voltage pulses," "tested for compliance with IEC 61846," "tested for compliance with IEC 60601-1"), rather than presenting quantitative acceptance criteria and the device's reported performance against them.

    Therefore, I cannot populate the table or answer the specific questions regarding sample size, data provenance, expert involvement, adjudication methods, MRMC studies, standalone performance, or ground truth details for any specific acceptance criteria from this text.

    Intended Use

    The EHL probe is designed for use with Potent Medical Electrohydraulic Lithotripter (TCS-B3-II) for disintegration of concernments in the bile duct.

    Device Description

    The SCDG -AS, SCDG -BS, and SCDG CS are sterile, single-use electrohydraulic lithotripsy (EHL) probes. These probes are designed to be used with the Electrohydraulic Lithotripter (TCS-B3-II) for the fragmentation of biliary calculi. The probes deliver low-energy electrical pulses through a dedicated connection to the generator, generating hydraulic shock waves in a saline medium to fragment stones in the biliary tract.

    AI/ML Overview

    The provided text is a 510(k) summary for a medical device (EHL probe) seeking FDA clearance. It describes the device, its intended use, comparison to a predicate device, and performance data from bench testing. However, it does not contain information about a clinical study involving human subjects or AI algorithms, which is typically where the concepts of "acceptance criteria," "human readers improve with AI vs without AI assistance," "standalone performance," "training set," and "ground truth establishment" would be relevant.

    The document primarily focuses on bench testing to demonstrate substantial equivalence to a legally marketed predicate device. This type of submission relies on the device meeting certain engineering specifications and performance characteristics, rather than a clinical trial with specific diagnostic accuracy metrics.

    Therefore, many of the requested details about acceptance criteria and study design are not applicable (N/A) based on the provided text.

    Here's a breakdown of the information that can be extracted from the document, along with an explanation for the N/A sections:

    Acceptance Criteria and Device Performance (Based on Bench Testing)

    The document does not present a formal table of "acceptance criteria" and "reported device performance" in the way one would establish for, say, an AI-powered diagnostic device. Instead, it describes various bench tests conducted to ensure the device meets safety and performance standards comparable to the predicate device. The implicit acceptance criterion for each test is that the probe performs as expected and similarly to the predicate device, demonstrating substantial equivalence.

    Acceptance Criteria (Implied from Bench Testing Objectives)Reported Device Performance (Summary from Text)
    Endoscope Compatibility: Smooth insertion and operation without damaging endoscope or probe.Probes were rigorously tested for compatibility with standard endoscopes, ensuring smooth insertion and operation.
    Visual Inspection: No defects or deviations from design specifications.Each probe underwent a meticulous visual inspection to identify any defects or deviations from the design specifications.
    Dimensional Verification: Critical measurements within specified tight tolerance limits.Critical measurements of the probes were taken to check that all dimensions fell within the tight tolerance limits specified in the design. Dimensions are smaller than the predicate device but core functionality is unaffected.
    Shockwave Efficacy: Generation of controlled and effective shockwaves.The ability of the probes to generate controlled and effective shockwaves was evaluated.
    Electrode Durability: Acceptable rate of electrode material consumption under normal usage.Monitoring the rate of electrode material consumption was pivotal in assessing the durability and longevity of the probes under normal usage conditions.
    Stone Fragmentation: Ability to fragment biliary stones consistently.Validated the system's ability to generate consistent high-voltage pulses and hydraulic shock waves capable of fragmenting biliary stones.
    Shockwave Pressure Attenuation: Comparable profile to predicate device, compliant with IEC 61846.Comparative analysis of maximum shock wave propagation distance and pressure attenuation profile between TCS-B3-II and predicate device EL27-Compact (K230488).
