    Permanent Beacon Transponder, Soft Tissue Beacon Transponder, Beacon Care Package - Soft Tissue (17G)

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

    The Calypso system is intended for use as an adjunct in treatment planning and radiation therapy, to align and/or monitor the patient's position relative to the isocenter of a radiation therapy system. The Calypso system provides accurate, precise and continuous localization of a treatment isocenter by using two or more Beacon transponders.

    Implanted Beacon transponders are indicated for use to radiographically and electromagnetically mark soft tissue for future therapeutic procedures.

    Permanent Beacon transponders are indicated for implantation in the prostate and peri-prostate tissue (i.e. prostatic bed), and in soft tissue to align and monitor the treatment in real time during radiation therapy.

    Device Description

    The Soft Tissue Beacon Transponder is a small, radiopaque, echogenic, electromagnetic fiducial marker designed for permanent implantation and intended for radiotherapy target localization to ensure accurate positioning for radiation therapy. It consists of a sealed biocompatible glass capsule containing a small, passive electrical circuit. The Soft Tissue Beacon Transponder may be used with the Calypso System (3.0 or later) as an electromagnetic fiducial marker, or with radiographic-based systems (e.g., kV x-ray, fluoroscopy, and CT) as a radiographic fiducial marker.

    Each transponder is implanted with a separate 17G introducer needle Introducer) in or near the tumor or Intended radiation target. Three Soft Tissue Beacon Transponders and three single use introducers are provided in each Beacon Care Package - Soft Tissue (17G). The device is single use and provided sterile.

    AI/ML Overview

    This document is a 510(k) summary for the Permanent Beacon Transponder Soft Tissue Beacon Transponder, provided in the Beacon Care Package - Soft Tissue (17G). It compares the new device to its predicate, the Beacon Care Package - Soft Tissue (14G) (K140823).

    Here's an analysis of the provided text in relation to acceptance criteria and study information:

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

    The document does not explicitly state acceptance criteria or device performance in quantifiable metrics. Instead, it focuses on demonstrating substantial equivalence to a predicate device. The core "acceptance criteria" here is that the new device (17G) is "No Change" or equivalent to the predicate device (14G) for specified characteristics.

    Calypso SystemFor use with v3.0 or higherNo ChangeEquivalentFor use with v3.0 or higher

    The explicit performance data or "acceptance criteria" for metrics like accuracy, precision, or localization capabilities are not present in this summary because the submission is for substantial equivalence based on technological characteristics being largely the same, with justifiable changes (e.g., smaller introducer needle and transponder). The assumption is that the performance established for the predicate device (K140823) carries over or is not adversely affected by the minor changes.

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

    This document does not contain any information about a specific test set, its sample size, or data provenance (country of origin, retrospective/prospective). This is a 510(k) summary focused on device description and comparison to a predicate, not a detailed clinical study report.

    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)

    This document does not contain any information about experts used to establish ground truth or their qualifications.

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

    This document does not contain any information about an adjudication method.

    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

    This document does not contain any information about an MRMC study or AI assistance. The device is a physical fiducial marker used with a radiation therapy system (Calypso System), not an AI-powered diagnostic tool.

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

    This document describes a physical medical device (fiducial marker) used in conjunction with a radiation therapy system. It is not an algorithm-only device, so a standalone algorithm performance study is not applicable and not mentioned.

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

    This document does not describe the type of ground truth used. As it's a 510(k) summary for a physical device and not a clinical study, this information is not expected here.

    8. The sample size for the training set

    This document does not contain any information about a training set or its sample size.

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

    This document does not contain any information about how ground truth for a training set was established.

    AI/ML Overview

    This document is a 510(k) summary for Varian Medical Systems' Soft Tissue Beacon Transponder, detailing its substantial equivalence to predicate devices. It does not contain information about a study that proves the device meets specific acceptance criteria with reported performance metrics, expert qualifications, or detailed study design. The document focuses on regulatory approval based on equivalence, not on a performance study against predefined criteria.

    Therefore, most of the requested information cannot be extracted from the provided text.

    Here's a breakdown of what can be extracted and what cannot:

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

    • Cannot be extracted. The document outlines indications for use and device characteristics, but it does not present specific acceptance criteria (e.g., minimum accuracy thresholds, signal strength requirements) or a study reporting performance against such criteria. The entire document is a substantial equivalence comparison, not a performance study report.

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

    • Cannot be extracted. No performance study or test set is described.

    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)

    • Cannot be extracted. No ground truth establishment for a test set is described.

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

    • Cannot be extracted. No adjudication method for a test set is described.

    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

    • Cannot be extracted. No MRMC study is mentioned. This device is a fiducial marker, not an AI-assisted diagnostic tool.

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

    • Cannot be extracted. The device is a physical fiducial marker, not an algorithm. Its function is to be implanted and tracked by a separate system (Calypso System or radiographic systems). Standalone algorithm performance is not applicable.

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

    • Cannot be extracted. No ground truth for a performance study is described.

    8. The sample size for the training set

    • Cannot be extracted. As this is a physical medical device (fiducial marker) and not a machine learning algorithm, the concept of a "training set" in this context does not apply.

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

    • Cannot be extracted. See point 8.
