Intended Use

The VIA™ 21 Microcatheter is intended for the introduction of non-liquid interventional devices (such as stents/flow diverters) and infusion of diagnostic (such as contrast media) or non-liquid therapeutic agents into the neuro, peripheral, and coronary vasculature.

Device Description

The VIA™ 21 Microcatheter is designed to be introduced over a steerable guidewire into the vasculature. The physician inserts the catheter into the vein or artery through the skin (percutaneous) using a sheath or guidewire. The device can then be navigated to the treatment site. Navigation is aided by the coated surface of the catheter which assists with manipulation while in the vasculature. Throughout the physician can obtain the position of the catheter by the tip marker using fluoroscopic techniques. Diagnostic, therapeutic and interventional devices can be delivered through the lumen of the catheter to the treatment site.

The VIATM 21 Microcatheter is a sterile single lumen device designed to aid the physician in accessing distal vasculature when used with a guide catheter and steerable guidewire. Variable shaft stiffness ranging from a flexible tip to a semi-rigid proximal section aid the physician in tracking over selectively placed guidewires. The proximal end of the catheter incorporates a standard luer adapter to facilitate attachment of accessories. A single radiopaque marker positioned at the distal tip facilitates fluoroscopic visualization. The outer surface of the catheter is coated with a hydrophilic coating which reduces friction during manipulation in the vessel. The inner lumen of the catheter has a PTFE liner which assists with delivery of interventional devices, such as an intraluminal flow diverter.

The VIA™ 21 Microcatheter is available in an effective length of 154 cm and an inner diameter of 0.021 inches.

The VIA™ 21 Microcatheter is presented in a tyvek pouch and is sterile, single use only and non-pyrogenic.

Accessories: Each VIA™ 21 Microcatheter is provided with a shaping mandrel to facilitate distal tip shaping.

In intravascular procedures, the device assists the physician in:

  • Accessing the targeted vasculature to facilitate the delivery of interventional devices, such as intraluminal flow diverters, infusion of diagnostic agents such as contrast and infusion of therapeutic agents.
AI/ML Overview

The provided document describes the VIA™ 21 Microcatheter and its non-clinical performance data to demonstrate substantial equivalence to predicate devices, rather than a study proving a device meets specific acceptance criteria for an AI/ML algorithm.

Therefore, many of the requested categories for AI/ML performance evaluation are not applicable to this document. The document focuses on the physical and functional characteristics of a medical device (a microcatheter).

However, I can extract the acceptance criteria and performance data for the device itself based on the provided text.

Here's the information derived from the document, with "N/A" for sections not relevant to this type of device and study:

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

Acceptance Criterion (Test)MethodologyReported Device Performance (Result & Conclusion)
Visual and DimensionalTests conformance to specified microcatheter dimensions and visual criteria. (ISO 10555-1:2013, TM036)Met performance specifications per DTM003. Complete conformance to standard.
Kink ResistanceMeasures diameter at which microcatheter shaft sections and junctions will kink. (BS EN 13868:2002, TM035)Met performance specifications per DTM003. Conformance to standard with the following deviations: Kink diameter determined based on mechanical kink (drop in compressive force) instead of 50% reduction in water flow. This method is appropriate as the Via 21 is primarily used to deliver non-liquid devices.
Tip BucklingTests force required for tip to buckle. (TM034)Met performance specifications per DTM003. Complete conformance to Sequent TM.
Tracking ForceTests force required to advance an interventional device through the microcatheter lumen. (TM032)Met performance specifications per DTM003. Complete conformance to Sequent TM.
Steam Shaping and Shape RetentionTests that microcatheter can be steam shaped to a clinically relevant angle and can maintain a minimum % of the initial angle after simulated use. (TM038)Met performance specifications per DTM003. Complete conformance to Sequent TM.
Shaft TensileMeasures the ultimate tensile strength of all Pebax and Vestamid junctions along the length of the catheter shaft. (ISO 10555-1:2013, TM031)Met performance specifications per DTM003. Complete conformance to standard.
Hub-Shaft TensileMeasures the ultimate tensile strength of the hub to shaft junction. (ISO 10555-1:2013, TM031)Met performance specifications per DTM003. Complete conformance to standard.
BurstMeasures peak pressure before microcatheter burst/liquid leakage. (ISO 10555-1:2013, TM037)Met performance specifications per DTM003. Complete conformance to standard.
Coating Friction and Coating IntegrityMeasures the average peak coating friction/lubricity. Coating integrity uses dye to test that coating remains adhered to catheter after simulated use. (Harland Medical Systems Coating Friction and Dye Test Methods, FDA Guidance Document, Class II Special Controls for PTCA Catheters (section 12) (Issued 2010))Met performance specifications per DTM003. Complete conformance to Harland test methods. In line with FDA guidance document on coating integrity.
Coating Adherence/ParticulateMeasures particulate generated from the hydrophilic coating on exterior of microcatheter, as well as particulate generated from advancing an interventional device through the inner lumen of the microcatheter. (TM042, FDA Guidance Documents)Met performance specifications per DTM003. Complete conformance to Sequent TM. In line with FDA guidance documents on particulate testing.
Flow RateMeasures flow rates through the microcatheter at defined injection rates using saline and contrast. (ISO 10555-1:2013)Met performance specifications per DTM003. Complete conformance to standard.
Hub PerformanceTests hub liquid and air leakage, as well as that the hub can withstand adequate forces. Tests that the hub meets general requirements for conical fittings. (ISO 594-1:1986, ISO 594-2:1998, TM043)Test results adopted from VIA 27/VIA33 (K132652). Conformance to standard with the following deviations: Used an alternative ISO 594-2:1998 fitting to test hubs for Separation Force and Unscrewing Torque. The fitting used was measured to have a minor diameter greater than called for in the standard. This was deemed as worst case for these tests, therefore acceptable to use. Only short term stress cracking was inspected for on hubs. ISO 594-2:1998 calls for inspection after 48 hours. Intended use of Via 21 microcatheter only requires RHV or syringes to be connected for short durations during delivery of implant, therefore long term testing is not applicable.

2. Sample size used for the test set and the data provenance

The document does not explicitly state sample sizes for each bench test, but refers to "Simulated Use Testing in Animals" with results summarized as "no new risks were identified and that the safety and effectiveness profile is similar to well-established comparison market-approved devices." This suggests animal testing was performed. The provenance is likely prospective as part of the device development and validation.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

N/A. This is a physical device, and the testing involves engineering and materials science principles, not expert interpretation of outputs like in an AI/ML system.

4. Adjudication method for the test set

N/A. Not applicable to engineering bench testing.

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

N/A. This is a physical medical device, not an AI/ML algorithm.

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

N/A. This is a physical medical device.

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

The ground truth for most of these tests relies on established engineering standards (ISO, ASTM, BS EN) and internal Sequent Test Methods (TM), which define acceptable physical, mechanical, and functional properties of catheters. For the biocompatibility testing, accepted biological endpoints (e.g., non-pyrogenic, non-toxic, non-hemolytic) serve as the ground truth.

8. The sample size for the training set

N/A. This is a physical medical device. There is no "training set" in the context of AI/ML.

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

N/A. This is a physical medical device.

Summary Statement of Substantial Equivalence
Use in a clinical setting was conducted in animals to show that no new risks were identified and that the safety and effectivenessprofile is similar to well-established comparison market-approved devices. Bench Testing was performed in models representingthe higher risk neurovascular anatomy, which is the worst case representation of the cardiac and peripheral vascular anatomies. TheViaTM 21 Microcatheter has equivalent performance characteristics to the comparison devices.
