Device includes shaping mandrel for distal tip adjustment. Used by physicians in clinical settings to deliver therapeutic/diagnostic agents or interventional implants. Benefits include precise access to distal vasculature and facilitated device delivery.
Clinical Evidence
No clinical data. Evidence consists of bench testing and simulated use testing in animals. Bench tests included visual/dimensional inspection, kink resistance, tip buckling, tracking force, steam shaping, shaft/hub tensile strength, burst pressure, coating friction/adherence, and particulate testing. All tests met performance specifications.

| PREDICATE<br>DEVICES | Marksman Catheter (K091559)<br>Excelsior XT-27 Microcatheter (K113778) |
| PRIOR SUBMISSION | There has been a prior submission for the subject device<br>and approval was obtained under K123477 for<br>peripheral and coronary indications |
| PURPOSE OF<br>SUBMISSION | The purpose of this submission is to gain marketing<br>clearance for an expansion of the Indications for Use to<br>include use of the VIATM and VIATM PLUS<br>Microcatheters in the neuro vasculature. The submission<br>also requests clearance to extend the shelf life from 6<br>months to 1 year. |
#### SUBSTANTIALLY EQUIVALENT TO:
The VIATM Microcatheter is substantially equivalent to the previously cleared Marksman™ Catheter (K091559), Excelsior XT-27 Microcatheter (K113778) and VIA™ Microcatheter (K123477).
{1}------------------------------------------------
#### DESCRIPTION OF THE DEVICE SUBJECT TO PREMARKET NOTIFICATION:
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.
#### INDICATIONS FOR USE:
The VIA™ Microcatheter is intended for the introduction of non-liguid 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.
#### TECHNICAL CHARACTERISTICS:
The VIA™ Microcatheter incorporates variable shaft stiffness ranging from a flexible tip to a semi-rigid proximal section aid the physician in tracking over a selectively-placed guidewire. The inner lumen incorporates a PTFE liner to facilitate movement of devices through the catheter's lumen to the intended destination in the vasculature. The outer surface of the catheter is coated with a hydrophilic coating which reduces friction during manipulation in the vessel. The tip of the catheter can be steam-shaped by physician for proper adjustment to the anatomy prior to use.

#### PERFORMANCE DATA:
Device performance testing confirms that the VIA™ Microcatheter can be used according to its intended use. The VIA™ Microcatheter has been verified and validated according to Sequent Medical's procedures for product design and development. Performance testing included:
- Bench Testing .
- . Sterilization Validation
- Packaging and Shelf Life Testing .
- Biocompatibility and Chemical Testing .
- . Simulated Use Testing in Animals
This testing regime demonstrates that the subject device is substantially equivalent to the legally marketed predicate device (s) for its intended use in the introduction of non-liquid interventional devices, infusion of diagnostic and therapeutic agents into the neuro, coronary, and peripheral vasculature.
The information provided by Sequent Medical in this 510(k) application was found to be substantially equivalent to all the predicate devices, including the Marksman™ Catheter (K091559), the Excelsior XT-27 Microcatheter (K113778) and the VIA™ Microcatheter (K123477)
#### NONCLINICAL TESTS DISCUSSION:
The nonclinical tests included:
- Physical characteristics unique to the VIA Microcatheter, such as visual and dimensional . tolerances, kink resistance, and catheter tip shape retention
- Safety features such as burst pressure, tensile force, and coating adhesion .
- . Functional characteristics such as navigation and track force in a worst-case model that incorporates two 360 degree loops, as well as interventional device retraction and catheter flow rate.
The following table lists the bench tests performed, the methodology/purpose of the test, the associated international standard (if applicable), and final results.
