Intended Use

The VIA™ 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 therapeutic agents into the neuro, peripheral and coronary vasculature.

Device Description

The VIA™ Microcatheter and VIA™ PLUS Microcatheter are designed to be introduced over a stcerable 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 procedure the physician can obtain the position of the catheter by the tip marker using fluoroscopic techniques. Interventional devices and infusion of diagnostic and therapeutic agents can be delivered through the lumen of the catheter to the treatment site.

The VIA™ Microcatheter is a sterile single lumen device with a single distal tip marker 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™ and VIA™ PLUS Microcatheter are available in effective lengths of 154 cm and 133 cm and inner diameters of 0.27 inches and 0.33 inches, respectively. For commercialization purposes the 0.027 inch diameter will be named the VIA™ Microcatheter and the 0.033 inch diameter will be named the VIA™ PLUS Microcatheter.

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

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

In line with FDA guidance document on coating integrity.

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 Internal test methodNot explicitly stated (implied by "Met performance specifications")Met performance specifications per standard and test methodConformance 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 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 Data Provenance

The provided text only mentions "bench tests performed" and "simulated use testing in animals." It does not specify the sample size for the test set (number of catheters tested for each bench test) or the data provenance (e.g., country of origin, retrospective or prospective).

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

Not applicable. This device is a microcatheter, and the evaluation relies on physical and functional bench testing, and simulated animal use, not on human interpretation of images or data requiring expert consensus or ground truth in the typical clinical AI context.

4. Adjudication Method for the Test Set

Not applicable, for the same reasons as #3.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and the Effect Size

No MRMC study was done. This is a medical device (microcatheter), not an AI algorithm for diagnostic interpretation. The evaluation focuses on the device's physical and functional performance, not on improving human reader performance.

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

This question is not applicable to a physical medical device like a microcatheter. The "standalone" performance here relates to the microcatheter's ability to perform its intended functions (e.g., track, burst pressure, kink resistance) as per its design specifications. The performance data presented in the table represents the standalone performance of the device against predefined technical specifications and standards.

7. The Type of Ground Truth Used

The ground truth for the performance testing is based on:

  • International Standards: ISO 10555-1:2009, BS EN 13868:2002, ISO 594-1:1986, ISO 594-2:1998.
  • FDA Guidance Documents: Class II Special Controls for PTCA Catheters (sections 12 & 13) and Non-Clinical Engineering Tests for Intravascular Stents and Associated Delivery Systems (section 12).
  • Supplier Test Methods: Harland Medical Systems Coating Friction and Dye Test Methods.
  • Sequent Medical Internal Test Methods (Sequent TM): For tests like Tip Buckling, Tracking Force, Steam Shaping and Shape Retention, Coating Adherence/Particulate, and Hub Performance.

Essentially, the "ground truth" is defined by the technical specifications, performance limits, and methodologies outlined in these various standards and internal protocols.

8. The Sample Size for the Training Set

Not applicable. This device is not an AI/ML algorithm that requires a training set. The term "training set" is relevant for AI models, not for traditional medical devices undergoing bench and simulated use testing.

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

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

Dear Ms. Parravi:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21
