Intended Use
The Synchro? Guidewire series is intended for general intravascular use, including neurovascular and peripheral vasculatures. It can be used to selectively introduce and position catheters and other interventional devices within the peripheral and neurovasculature. This device should be used only by physicians trained in percutaneous, intravascular techniques and procedures.
Device Description
Like the primary predicate device, the Synchro2 Support Guidewire is a single-use product with a shapeable tip in straight and pre-shape configurations used to gain intravascular access to and facilitate the positioning and exchange of interventional devices in small diameter, tortuous vasculature for neuro and peripheral diagnostic and interventional procedures. The wire can be torqued to facilitate navigation through the vasculature.
More Information

No
The document describes a physical guidewire and its intended use and performance testing, with no mention of software, algorithms, or AI/ML capabilities.

No
The device, a guidewire, is used to introduce and position other interventional devices. It does not directly treat a condition but rather facilitates procedures.

Yes

Explanation: The device description states that the guidewire is used for "neuro and peripheral diagnostic and interventional procedures," indicating its role in diagnostic processes.

No

The device description clearly indicates it is a physical guidewire, a hardware component, used for intravascular procedures.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the device is for "general intravascular use" to "selectively introduce and position catheters and other interventional devices within the peripheral and neurovasculature." This describes a device used within the body for procedural purposes, not for testing samples outside the body to diagnose conditions.
  • Device Description: The description details a guidewire used for navigation and positioning within the vasculature, consistent with an interventional device, not a diagnostic test.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting biomarkers, or providing diagnostic information based on laboratory testing.

IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens from the human body to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. This guidewire does not fit that description.

Dear Lorraine Mazzeo:

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

1

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.htm); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

Risk Assessment

Risk assessment of the modifications has been conducted in accordance with EN ISO 14971:2012. The risk documentation was updated to support the modifications, and Stryker Neurovascular has determined that the modifications to the primary predicate device raise no new questions of safety or effectiveness. The modifications did not result in any new failure modes nor were there any changes to existing failure modes. Results of confirmatory testing have demonstrated the subject device is substantially equivalent to the primary predicate device.

Testing Summary

The results of confirmatory testing conducted on the subject device demonstrate that it performs as designed and is suitable for its intended use. Specifically, the following tests were performed on the subject device.

TestConclusions
Tip StiffnessMet established acceptance criteria
FractureMet established acceptance criteria
Tip IntegrityMet established acceptance criteria
Particulate characterizationMet established acceptance criteria
Coating integrity visual inspectionMet established acceptance criteria

Biocompatibility

Biocompatibility testing was completed for the previously cleared devices under K053268. These results apply to the subject device because it uses the same materials and processes as previously cleared primary predicate device. The results demonstrate that the subject device with its accessories meet biological safety requirements per EN ISO 10993-1:2009 ("Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process") for externally communicating medical devices with circulating blood contact for less than 24 hours. This statement is supported by standards assessment conducted by Stryker.

8

Sterilization and shelf life

The device and its accessories, are sterilized by 100% Ethylene Oxide and have been adopted into a validated sterilization process in accordance with the principles of EN ISO 11135: 2014/AC: 2014 ("Sterilization of health-care products - Ethylene oxide - Requirements for the development, validation and routine control of a sterilization process for medical devices"). This statement is supported by standards assessment conducted by Stryker.

There are no material changes. All components that are changing are metal, which are not affected by aging. There are no changes to existing shelf life.

Summary of Substantial Equivalence

The subject device is substantially equivalent to the primary predicate device with regards to device design, materials, intended use, and patient population. The conclusions drawn from the risk assessments and confirmatory testing conducted demonstrate that the subject device performs as designed, is as safe, as effective, and performs as well as the predicate device.
