    The GALAXY G3 Mini Microcoil Delivery System is intended for endovascular embolization of intracranial aneurysms, other neurovascular abnormalities such as arteriovenous malformations fistulae, and is also intended for arterial and venous embolizations in the peripheral vasculature.

    Device Description

    The MICRUSFRAME, DELTAFILL, DELTAXSFT, GALAXY G3, GALAXY G3 XSFT, and GALAXY G3 Mini Microcoil Delivery Systems consist of three components: a Microcoil System, a connecting cable, and a Detachment Control Box (DCB). Each component is sold separately.

    The Microcoil System consists of a microcoil attached to a Device Positioning Unit (DPU). The Microcoil System is packaged in an introducer sheath designed to protect the coil in the packaging dispenser and to provide support for introducing the coil into the microcatheter. The microcoil is the implantable segment of the device and is detached from the Device Positioning Unit (DPU) using the Detachment Control System (Detachment Control Box and connecting cable).

    For the MICRUSFRAME, DELTAFILL, DELTAXSFT, GALAXY G3, and GALAXY G3 XSFT microcoils: The microcoil is fabricated from a platinum alloy wire. The wire is wound into a primary coil which may contain either a polypropylene suture (SR) or an absorbable polymer suture and then formed into a secondary shape. The secondary shape may be spherical, complex, or helical.

    For the GALAXY G3 Mini microcoils: The microcoil is fabricated from a platinum alloy wire. The wire is wound into a primary coil which contains a polypropylene suture (SR) and then formed into a secondary shape. The secondary shape is complex.

    For all Microcoil Delivery Systems: The DPU is a variable stiffness wire and has a radiopaque marker band located three (3) cm from its distal end. The Device Positioning Unit includes five (5) fluoro saver markers on the proximal section of the shaft. The markers are intended to indicate when the tip of the microcoil is approaching the tip of the microcatheter. When the distal-most marker reaches the proximal end of the Rotating Hemostatic Valve (RHV) on the microcatheter, the tip of the coil is approaching the tip of the microcatheter and fluoroscopy should be used to guide further coil insertion.

    The introducer sheath has three main components: an introducer tip, a translucent introducer body, and a re-sheathing tool.

    The ENPOWER Detachment Control Box (DCB) provides the energy necessary to allow for a thermo-mechanical detachment of the microcoil from the DPU. The connecting cable delivers the energy necessary to detach the embolic coil from the Microcoil System's detachment zone. The connecting cable is connected between the Microcoil System's hub connector on the DPU and the output connector on the DCB.

    The connecting cables may be one of two types: one with a remote detach button (the ENPOWER Control Cable) catalog no. ECB000182-00, or one without a detach button (standard connecting cable) catalog no. CCB00157-00. The ENPOWER Detachment Control Box, catalog no. DCB2000500, works with the ENPOWER Control Cable and with the standard connecting cable.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for microcoil delivery systems, which are medical devices, not an AI/ML powered device. Therefore, a study proving an AI/ML device meets acceptance criteria is not presented in this document.

    The document discusses non-clinical performance data for the microcoil delivery systems, specifically focusing on verification and validation testing of minor design modifications related to the Device Positioning Unit's core wire.

    Here's the information regarding the device's acceptance criteria and the study that proves it meets them, based on the provided text, adapted for the context of a medical device rather than an AI/ML system:

    1. Table of Acceptance Criteria and Reported Device Performance

    TestAcceptance Criteria SummaryReported Device Performance
    Tracking Force (delivery) - VerificationNot explicitly stated, but "established acceptance criteria" implies a threshold.Pass
    Simulated Use: Tracking Force (delivery) - ValidationNot explicitly stated, but "established acceptance criteria" implies a threshold.Pass
    Simulated Use: Microcatheter Stability - ValidationNot explicitly stated, but "established acceptance criteria" implies a threshold.Pass

    2. Sample Size Used for the Test Set and Data Provenance

    • Sample Size: Not explicitly stated. The document mentions "Samples" in the results, but doesn't quantify the number of units tested for each criterion.
    • Data Provenance: The tests were conducted internally as "bench testing." The country of origin is not specified, but the applicant, Medos International SARL, is located in Le Locle, Switzerland. The testing is retrospective, as it's part of a 510(k) submission for an already manufactured device with minor modifications.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    This is not applicable as the study involved non-clinical bench testing of a physical medical device, not a diagnostic or prognostic system requiring expert interpretation of data or images. The "ground truth" here is determined by the physical properties and performance measured during the tests.

    4. Adjudication Method for the Test Set

    Not applicable. The tests are objective measurements of physical performance and do not involve human adjudication in the typical sense of reviewing subjective interpretations.

    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 is not an AI/ML device, and no MRMC study was performed. The document explicitly states: "Clinical studies were not required as appropriate verification and validation of the minor design modifications was achieved based on the bench testing."

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

    Not applicable. This is not an AI/ML device.

    7. The Type of Ground Truth Used

    The "ground truth" for the non-clinical testing was defined by objective physical measurements and engineering specifications, which determine whether the device meets its design requirements. For example, "tracking force" would have a specified maximum force for successful delivery, and "microcatheter stability" would have an acceptable range of movement.

    8. The Sample Size for the Training Set

    Not applicable. This is not an AI/ML device, so there is no training set in the AI/ML context.

    9. How the Ground Truth for the Training Set Was Established

    Not applicable. As above, there is no AI/ML training set.

    GALAXY G3 Mini Microcoil Delivery System

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The GALAXY G3 Mini Microcoil Delivery System is intended for endovascular embolization of intracranial aneurysms, other neurovascular abnormalities such as arteriovenous malformations fistulae, and is also intended for arterial and venous embolizations in the peripheral vasculature.

    Device Description

    The GALAXY G3 Mini Microcoil Delivery Systems consist of three components, a Microcoil System, a connecting cable, and a Detachment Control Box (DCB). Each component is sold separately. As shown in Figure 1, the Microcoil System consists of a microcoil attached to a Device Positioning Unit (DPU). The Microcoil System is packaged in an introducer sheath designed to protect the coil in the packaging dispenser and to provide support for introducing the coil into the microcatheter catheter. The microcoil is the implantable segment of the device, and is detached from the Device Positioning Unit (DPU) using the Detachment Control System (Detachment Control Box and connecting cable). The microcoil is fabricated from a platinum alloy wire. The wire is wound into a primary coil which contains a polypropylene suture (SR) and then formed into a secondary shape. The secondary shape is complex. The DPU is a variable stiffness wire and has a radiopaque marker band located three (3) cm from its distal end. The Device Positioning Unit includes five (5) fluoro saver markers on the proximal section of the shaft. The markers are intended to indicate when the tip of the microcoil is approaching the tip of the microcatheter. When the distal-most marker reaches the proximal end of the Rotating Hemostatic Valve (RHV) on the microcatheter, the tip of the coil is approaching the tip of the microcatheter and fluoroscopy should be used to guide further coil insertion. The introducer sheath has three main components: an introducer tip, a translucent introducer body, and a re-sheathing tool. The EnPOWER Detachment Control Box (DCB) provides the energy necessary to allow for a thermo-mechanical detachment of the microcoil from the DPU. The connecting cable delivers the energy necessary to detach the embolic coil from the Microcoil System's detachment zone. The connecting cable is connected between the Microcoil System's hub connector on the DPU and the output connector on the DCB. The connecting cables may be one of two types: one with a remote detach button (the EnPower Control Cable) catalog no. ECB000182-00, or one without a detach button (standard connecting cable) catalog no. CCB00157-00. The EnPower Detachment Control Box works with the EnPower Control Cable and with the standard connecting cable.

    2. Sample Size Used for the Test Set and Data Provenance

    The document does not explicitly state the exact sample sizes used for each individual performance test (test sets). It generally refers to "samples" being tested.

    The data provenance is bench testing, which implies the data was collected within a laboratory setting, likely in the US, given the submission to the FDA. It is retrospective in the sense that it's testing a finished device against predetermined criteria.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    No individual experts or their qualifications are mentioned for establishing ground truth for the bench tests. The "ground truth" for these tests is based on established engineering specifications, industry standards (e.g., USP788, ISO standards), and clinical relevance/simulated use scenarios. For the "Overall Coil Performance" test, "physician's satisfaction rating" was evaluated, implying input from medical professionals, but the number and qualifications are not specified.

    4. Adjudication Method for the Test Set

    Not applicable for the reported tests. The tests are primarily objective measurements against established criteria, or visual inspections by qualified personnel (not specified as "experts" in the context of adjudication).

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

    No, an MRMC comparative effectiveness study was not done. The document explicitly states: "A clinical study was not required as appropriate verification and validation of the GALAXY G3 Mini Microcoil Delivery System was achieved based on the similarities of the proposed device to the predicate device, and from results of bench testing."

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

    Not applicable. This device is a physical medical device (microcoil delivery system), not an algorithm or AI software. Therefore, the concept of "standalone algorithm performance" does not apply. The performance tests are for the physical device itself.

    7. The Type of Ground Truth Used

    The ground truth for the bench tests is based on:

    • Engineering specifications and design requirements: For dimensional checks, material properties, and functional performance (e.g., spring constant, detachment force, tensile strength).
    • Industry standards: Such as USP788 for particulate matter, ISO 11607 for packaging, ISO 10993-1 for biocompatibility, and ISO 11135-1 for sterilization.
    • Simulated use in clinically relevant models: For tests like track force, coil durability, detachment durability, resheathing reliability, fluoro saver marker durability, and distal outer sheath durability.
    • Physician satisfaction rating: For "Overall Coil Performance" compared to a predicate device, which implies a subjective expert assessment.

    8. The Sample Size for the Training Set

    Not applicable. This is a physical medical device, not an AI or machine learning model that requires a "training set." The listed studies are verification and validation tests for the device itself.

    9. How the Ground Truth for the Training Set Was Established

    Not applicable, as there is no training set for this device.
