Intended Use

The Surefire® Hi-Flow Microcatheter is intended for use in angiographic procedures. It delivers radiopaque media and therapeutic agents to selected sites in the peripheral vascular system.

Device Description

The Surefire® Hi-Flow Microcatheter is an 0.027" lumen microcatheter with the Surefire Expandable Tip at the distal end. It has an outer sheath to facilitate deployment and retraction of the Surefire Expandable Tip. The infusion catheter serves as the conduit for physician-specified agents such as contrast agents, flush solutions, and embolic beads. It is compatible with standard 0.018" guide wires, infusion syringes, rotating hemostatic valves (RHVs), and embolic particles 700µm or less in size. The proximal end of the device features a female luer lock hub. The microcatheter has a Teflon inner liner to provide a lubricious surface for passage of physician-specified agents and other accessory devices. The outer sheath is hydrophilically coated. The usable length of the device is 120cm. The distal soft, pliable, funnel-shaped Surefire Expandable Tip is available in two tip sizes, targeted to treat vessels of 3.0 - 4.5 mm and 4.0 - 6.0 mm.

AI/ML Overview

The Surefire® Hi-Flow Microcatheter is intended for use in angiographic procedures, delivering radiopaque media and therapeutic agents to selected sites in the peripheral vascular system. The provided document details the performance testing and verification conducted to demonstrate the device's substantial equivalence to a predicate device, the Surefire Infusion Catheter System (K110459).

1. Acceptance Criteria and Reported Device Performance

The document states that a "battery of tests was performed according to protocols based on the requirements of recognized standards and was shown to meet the acceptance criteria that were determined to be applicable to the safety and efficacy of the device." While specific numerical acceptance criteria values are not explicitly given in the provided text, the list of tests performed and the overall conclusion of substantial equivalence serve as the reported performance.

Overall Safety/EfficacyRisk/Hazard AnalysisConducted according to EN ISO 14971; recognized standards (ISO 10555-1, ISO 10555-2) reviewed.
Substantial EquivalenceDemonstrated through bench tests; device is as safe and effective as the predicate device (Surefire Infusion Catheter System, K110459).

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

The document does not specify the exact sample sizes used for each individual performance and biocompatibility test. It mentions that "test data provided in bench tests demonstrate that the device is as safe, as effective, and performs at least as safely and effectively as the predicate device."

The tests are described as "bench tests," indicating they were conducted in a laboratory setting rather than involving human or animal subjects. The data provenance is industrial/laboratory testing conducted by the manufacturer, Surefire Medical, Inc. The country of origin for the data is not explicitly stated, but the manufacturer has addresses in Westminster, CO, and Miami, FL, implying the testing was done in the USA. The nature of these tests (bench tests) means they are prospective for the purpose of regulatory clearance.

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 section is not applicable (N/A) for this device and study. The Surefire® Hi-Flow Microcatheter is a medical device, not an AI/software device that requires expert human interpretation to establish ground truth for image analysis or similar diagnostic tasks. The "ground truth" for this device is established by meeting engineering specifications, biocompatibility standards, and demonstrating functional performance through objective physical tests, rather than expert consensus on diagnostic images or clinical outcomes.

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

This section is N/A for this device. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies or studies involving human readers/interpreters to resolve discrepancies in diagnoses or interpretations. The tests described for the microcatheter are objective physical and chemical tests, not involving human interpretation that would require adjudication.

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 section is N/A. The Surefire® Hi-Flow Microcatheter is a physical medical device, not an AI system. Therefore, no MRMC study or assessment of human reader improvement with or without AI assistance was conducted or is relevant.

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

This section is N/A. The device is a physical microcatheter, not an algorithm or AI system. Its performance is inherent in its design and manufacturing, tested objectively through bench tests.

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

The "ground truth" for the Surefire® Hi-Flow Microcatheter is established by objective engineering performance specifications, recognized industry standards (e.g., ISO, ASTM, USP), and regulatory requirements. For example:

  • Mechanical Integrity: Ground truth is defined by the physical limits the device must withstand (e.g., pull strength, high pressure injection) without failure, as per engineering design and relevant standards.
  • Biocompatibility: Ground truth is defined by the absence of toxic, irritating, sensitizing, or thrombogenic reactions when tested against established biological safety standards (e.g., ISO 10993 series, ASTM, USP).
  • Functional Performance: Ground truth for infusion efficiency and antegrade flow is defined by the device's ability to perform its intended function within specified parameters, typically benchmarked against predicate device performance or clinical needs.

8. The sample size for the training set

This section is N/A. The device is a physical medical device, not a machine learning model, and therefore does not have a "training set" in the context of AI or algorithm development.

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

This section is N/A, as there is no training set for this physical device.

Performance/Safety: A risk/hazard analysis was conducted according to EN ISO 14971

(Medical Devices-Application of Risk management to medical devices). Performance characteristics for this indication for use were identified which included a review of both ISO 10555-1 (Intravascular catheters -Sterile and single-use catheters - Part 1: General requirements) and ISO 10555-2 (Sterile, single-use intravascular catheters - Part 2: Angiographic catheters). It was then determined that the performance of the Surefire® Hi-Flow Microcatheter is substantially equivalent to the performance and safety of the Surefire Infusion Catheter System. A battery of tests was performed according to protocols based on the requirements of recognized standards and was shown to meet the acceptance criteria that were determined to be applicable to the safety and efficacy of the device.

Additional Safety Information:

Manufacturing controls include visual; functional, dimensional and sterility tests. Blood contacting materials were tested in accordance with the tests recommended in the FDA General program Memorandum. Use

{2}------------------------------------------------

Substantial

Equivalence:

of International Standard ISO 10993, "Biological Evaluation of Medical Devices Part -1 Evaluation and testing".

The Surefire® Hi-Flow Microcatheter is substantially equivalent in intended use, design, and technology/principles of operation to the predicate. Both devices share the same Indications for Use. Both devices make use of the Surefire Expandable Tip at the distal end of the microcatheter to increase the infusion efficiency of the device while maintaining sufficient antegrade flow. Both systems are compatible with solutions containing embolic agents, specifically hydrogels ≤ 700 µm and glass beads ≤ 190 um. Both devices include configurations intended for use in vessels of 4.0 - 6.0 mm in diameter. The proposed device contains an additional configuration for use in vessels of 3.0 - 4.5 mm in diameter. The Microcatheter is substantially equivalent to the Surefire® Infusion Catheter System, cleared under K110459. Differences between the devices do not raise any issues of safety or effectiveness.

Test data provided in bench tests demonstrate that the device is as safe, as effective, and performs at least as safely and effectively as the predicate device.
