No
The summary describes a physical guidewire and its accessories, with no mention of software, algorithms, or data processing that would indicate the use of AI/ML. The performance studies focus on physical and mechanical properties.
No
The device is a guidewire used to introduce and position other interventional devices; it does not directly treat a medical condition.
No
The device is a guidewire intended to introduce and position other interventional devices, not to diagnose a medical condition. Its function is to facilitate procedures, not to provide diagnostic information.
No
The device description clearly details a physical guidewire with material properties, coatings, and accessories, indicating it is a hardware device.
Based on the provided information, the Volo 14 Guidewire is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states it's for "general vascular use within the neuro and peripheral vasculatures to introduce and position catheters and other interventional devices." This describes a device used within the body for procedural purposes, not for testing samples outside the body.
- Device Description: The description details a physical guidewire designed for navigation within blood vessels. It mentions coatings, a radiopaque marker, and accessories for manipulation, all consistent with an invasive medical device.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, tissue, etc.), reagents, or any process related to diagnosing a condition based on in vitro testing.
In summary, the Volo 14 Guidewire is an invasive medical device used for interventional procedures, not an IVD.
N/A
Intended Use / Indications for Use
The Volo 14 Guidewire is intended for general vascular use within the neuro and peripheral vasculatures to introduce and position catheters and other interventional devices. The guidewire is not intended for use in the coronary vasculature.

Device Description
The Volo 14 Guidewire is a modification of Scientia Vascular's Aristotle 14 Guidewire. It is a 0.014" diameter steerable guidewire with a shapeable tip to aid in accessing vasculature. The guidewire is supplied sterile and is for single use only. It is provided in a range of stiffness profiles, from soft to standard. The product is provided in 200cm and 300cm lengths.
The distal portion of the guidewire tip includes a radiopaque platinum wire marker coil to facilitate fluoroscopic visualization. The guidewire has a hydrophilic polymer coating on the distal portion and a polytetrafluoroethylene (PTFE) coating on the proximal portion to reduce friction during manipulation in vessels.
The guidewire is provided with an introducer (to aid with the insertion of the guidewire into a catheter hub and/or a hemostasis valve) and a torque device (to attach to the proximal portion to facilitate gripping and manipulation of the guidewire during use). The introducer and torque accessory devices are included to facilitate use of the guidewire and are not intended to contact the patient's body.
The Volo 14 Guidewire is substantially equivalent with respect to technological characteristics, design and materials to the previously cleared Aristotle 14 Guidewire.

Dear David Sabodski:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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

The only difference between Volo 14 Guidewires and Aristotle 14 Guidewires is in the construction of the guidewire tips. The cut profile of the Nitinol tip in the Volo 14 Guidewire has been modified to slightly chnage the flexibility of the tip.
The Volo 14 Guidewires will be supplied with a blue torque device, whereas the Aristotle 14 Guidewires are supplied with a green torque device. Both torque devices are supplied by Merit Medical and have the same 510(k) approval, K936032.
NON-CLINICAL PERFORMANCE TESTS
Biocompatibility
The materials used in the manufacture of the subject Volo 14 Guidewire are identical to those used in the manufacture of the Aristotle 14 Guidewire also manufactured by Scientia Vascular LLC, cleared January 22, 2018 after review of K173235; in formulation, processing, sterilization, and geometry, and no other chemicals have been added (e.g., plasticizers, fillers, color additives, cleaning agents, mold release agents).
Consequently, no additional evaluations are needed to determine that the subject guidewires present a low and acceptable biological and toxicological risk when used in accordance with their intended and indicated uses, and no additional information is provided in this 510(k).
Sterilization
100% EO is used to sterilize the device to achieve a SAL of at least 100°. The device was adopted into an EO sterilization processing group in accordance with AAMI TIR 28:2016. Completion of the review performed to the requirements of AAMI TIR 28:2016 indicate the Volo 14 and the Aristotle 14 are similar with regards to all device and packaging characteristics that could affect the ability to sterilize the devices.
