Intended Use
The Savion DLVR and Savion FLX Guidewires are intended to facilitate the placement and exchange of balloon dilatation catheters or other interventional therapeutic devices during PTCA, PTA, or other intravascular interventional procedures. They are not intended for use in the cerebral vasculature.
Device Story
Savion DLVR and Savion FLX are intravascular guidewires used to facilitate placement/exchange of balloon dilatation catheters or interventional therapeutic devices during PTCA, PTA, or other intravascular procedures. Devices feature metal core wire with ICE hydrophilic coating and PTFE-coated proximal section; varying tapers and tip materials (spring coil or polymer) provide specific rail support and tip flexibility. Available in 0.014 in diameter and 182 cm, 185 cm, or 300 cm lengths. 182/185 cm models support exchange via AddWire Extension Wire; 300 cm models allow exchange without extension. Used by clinicians in interventional settings; provides mechanical support and guidance for therapeutic devices within vasculature.
Clinical Evidence
No clinical data provided. Substantial equivalence supported by bench testing per FDA Guidance for Coronary and Cerebrovascular Guide Wires (1995), including biocompatibility (cytotoxicity, hemolysis, pyrogenicity, etc.) and mechanical performance testing (tensile strength, torque, flexibility, coating integrity).
Technological Characteristics
Metal core wire; ICE hydrophilic coating; PTFE proximal coating. 0.014 in diameter; 182 cm, 185 cm, 300 cm lengths. Tip materials: spring coil or polymer. Mechanical design features varying tapers for rail support and tip flexibility. Sterilization method not specified.
Indications for Use
Indicated for patients undergoing PTCA, PTA, or other intravascular interventional procedures requiring placement or exchange of balloon dilatation catheters or interventional therapeutic devices. Contraindicated for use in the cerebral vasculature.
Regulatory Classification
Identification
A catheter guide wire is a coiled wire that is designed to fit inside a percutaneous catheter for the purpose of directing the catheter through a blood vessel.
Special Controls
*Classification.* Class II (special controls). The device, when it is a torque device that is manually operated, non-patient contacting, and intended to manipulate non-cerebral vascular guide wires, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

# Dear Jake Baldauf:
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 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820);
{1}------------------------------------------------
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). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.
For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic.

### Device Description
The Boston Scientific Savion DLVR and Savion FLX Guidewires with ICE® Hydrophilic Coating are available with a nominal diameter of 0.014 in (0.37 mm) and in nominal lengths of 182 cm, 185 cm, or 300 cm. These guidewires contain a metal core wire. Varying tapers along the core wire and differing tip materials (spring coil or polymer) provide combinations of rail support and tip flexibility to address user requirements. The proximal core wire section of all models is coated with polytetrafluoroethylene (PTFE) for lubricity.
The 182 cm and 185 cm guidewires are designed with an extension section for exchange of Over-the-Wire systems by using the AddWire™ Extension Wire (K030617). The 300 cm guidewires allow exchange of therapeutic devices without the use of an exchange system.
# Intended Use/ Indications for Use
The Savion DLVR and Savion FLX Guidewires are intended to facilitate the placement and exchange of balloon dilatation catheters or other interventional therapeutic devices during PTCA, PTA, or other intravascular interventional procedures. They are not intended for use in the cerebral vasculature.
# Comparison of Required Technological Characteristics
The Savion FLX Guidewire and Savion DLVR Guidewire incorporate substantially equivalent design, fundamental technology, packaging, sterilization method and intended use as the predicates PT2 Guidewire (K030617), Mailman Guidewire (K143587), respectively.
