    Intended Use

    In selective areas of peripheral and coronary vessels, the Bullfrog Micro-Infusion Device is intended for the infusion of diagnostic and therapeutic agents that are indicated for delivery into the vessel wall or perivascular area. The Bullfrog Micro-Infusion Device is also intended for the infusion of diagnostic and therapeutic agents intraluminally.

    Device Description

    The Mercator MedSystems Bullfrog Micro-Infusion Device is a wire-guided, singleoperator, endovascular catheter that consists of a perpendicular microneedle, which is sheathed by and contained within a semi-rigid polymer actuator balloon. The device is designed to be advanced to target vasculature and hydraulically actuated to move the microneedle through the external elastic lamina to deliver substances to adventitial and perivascular tissues. A compliant stabilizing balloon inflates with the actuator to provide a force opposite the needle tip for proper seating of the needle is retracted within the sheathing structure by vacuuming the hydraulic actuator.

    AI/ML Overview

    Here's an analysis of the provided text regarding the acceptance criteria and study for the Bullfrog Micro-Infusion Device, based only on the input you provided.

    Note: The provided document is a 510(k) summary for a medical device. These summaries typically highlight that performance tests were done and met criteria, but they do not usually contain the detailed acceptance criteria or the full study results that would be found in a complete test report or clinical study report. Therefore, much of the requested information (especially specific numerical acceptance criteria, detailed study parameters, and specific quantitative results) is not present in this document.

    While the document states that performance testing, biocompatibility, sterilization validation, and in-vivo safety and effectiveness studies were conducted and all tests met pre-determined specifications and acceptance criteria, it does not provide the specific acceptance criteria or the detailed results of these studies. It also explicitly states "N/A" for "Indications for Use" under a section heading, which is likely a formatting error as it also lists indications for use earlier in the document.

    Risk Profile ComparisonSame risk profile as the predicate device (qualitative)Risk analysis has shown that the Bullfrog Micro-Infusion Device has the same risk profile as the predicate.

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

    The document does not explicitly state the sample sizes used for any specific test sets (e.g., for mechanical, fluid delivery, or in-vivo studies). It also does not specify the country of origin of the data or whether the studies were retrospective or prospective. It only mentions "in-vivo safety and effectiveness studies" without details.

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

    This information is not provided in the document. The document describes a medical device, and the "ground truth" concept as usually applied to AI algorithms (e.g., expert consensus on images) is not applicable or detailed here. For device performance, the "ground truth" would typically be defined by the physical or biological reality measured during testing against defined specifications.

    4. Adjudication Method for the Test Set

    This information is not provided in the document.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size

    No MRMC comparative effectiveness study is mentioned for the Bullfrog Micro-Infusion Device. This type of study is typically associated with diagnostic imaging or AI algorithms, not directly with a physical interventional medical device as described here.

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

    The Bullfrog Micro-Infusion Device is a physical interventional medical device, not an algorithm. Therefore, "standalone algorithm performance" is not applicable in this context.

    7. The Type of Ground Truth Used

    For a physical device, the "ground truth" is established through engineering specifications, physical measurements, chemical analyses (biocompatibility), and biological outcomes (in-vivo studies, safety/effectiveness). The document generally states that tests met "pre-determined specifications and acceptance criteria," which implies that these specifications serve as the "ground truth" against which performance was measured. No specific mention of expert consensus, pathology, or outcomes data as a distinct ground truth source (like in imaging studies) is given for the device's technical performance.

    8. The Sample Size for the Training Set

    This information is not applicable. The Bullfrog Micro-Infusion Device is a physical medical device, not an AI algorithm that requires a training set.

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

    This information is not applicable, as it is a physical device and not an AI algorithm.
