Coil materials include stainless steel, palladium, platinum, or tungsten. Guidewires may feature PTFE or silicone coating and proximal core markers. Used in angiographic procedures by physicians to introduce and position catheters and interventional devices within coronary and peripheral vasculature. Device provides mechanical guidance for interventional tools. Benefits include facilitating navigation through vasculature during diagnostic or therapeutic procedures. ## Clinical Evidence Bench testing only. Testing included visual/tactile inspection, dimensional/mechanical attributes, radiopacity, lubricity, J-memory, stiffness, adhesion/durability, pull test, torque strength/control, particulate testing, and ISO-standard tests (strength of union, flex, corrosion, fracture, hydrodurability). Biocompatibility testing (cytotoxicity, hemolysis) confirmed safety of tungsten addition. ## Technological Characteristics Core: Nitinol or stainless steel. Coil: Stainless steel, palladium, platinum, or tungsten. Coating: PTFE or silicone. Dimensions: 20cm-500cm length, 0.014"-0.35" diameter. Sensing/Actuation: Mechanical guidance. Standards: ISO 10993 (biocompatibility), ISO 11070 (introducer needles/catheters/guidewires), ISO 11135 (sterilization). ## Regulatory 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. ## Predicate Devices - Mandrel Guidewires (Lake Region Medical) ([K011084](/device/K011084.md)) - Mandrel Guidewires (Lake Region Medical) ([K022759](/device/K022759.md)) - Mandrel Guidewires (Lake Region Medical) ([K033758](/device/K033758.md)) - Mandrel Guidewires (Lake Region Medical) ([K080144](/device/K080144.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The logo consists of a red circular design on the left, followed by the words "Lake Region" in a bold, serif font. Below "Region" is the word "Medical" in a smaller font size. The logo is clean and professional, suggesting a healthcare organization. ### TECHNOLOGICAL CHARACTERISTICS 2.10 The design specifications are substantially equivalent to the existing Mandrel Guidewires. Material used for the coil of the guidewire will include the addition material option of Tungsten. ### 2.11 QUALITY SYSTEM CONTROL ## DESIGN CONTROLS LRM is in conformance with the design control procedure requirements as specified in 21 CFR Part 820.33. Risk analysis was completed by means of a Failure Mode and Effects Analysis and all verification and validation activities resulted in the ability to demonstrate that the predetermined acceptance criteria were met. ## MATERIALS / SUPPLIER / PRODUCT / PROCESS CONTROLS LRM has formal quality systems in placed to assure that each product manufactured remains equivalent to the predicate products, and that the changes will not have an adverse effect on safety or effective use of the product. The quality systems include Engineering Change Order Review, Material Qualification, Supplier Qualification, Product Qualification, and Process Qualification. These controls are applied to each product size / group. #### 2.12 QUALIFICATION TESTING The conclusions drawn from bench testing and biocompatibility testing demonstrate compliance with the design input summary which shows the device is at least as safe and effective as the current legally marketed device. ### BENCH TESTING In order to demonstrate equivalence of the guidewire, Lake Region Medical performed bench testing to establish requirements. Test devices were manufactured and inspected according to established requirements for visual/tactile, dimensional and mechanical attributes. The devices were then subjected to the following test methods to show the devices comply with the design input summary: - Visual - Radiopacity - Lubricity - J-Memory Test - Body Stiffness - Adhesion / Durability - Guidewire Pull test - · Torque Strength • Torque Control - Dimensional • Linear Stiffness - Lateral Stiffness - Particulate Test - ISO Strength of Union - ISO Flex Test - ISO Corrosion Resistance Test - · ISO Fracture Test - · Hydrodurability - BIOCOMPATIBILITY TESTING Biocompatibility testing per the design input summary requirements show the addition of Tungsten to the device does not affect the biocompatibility of the device is still in compliance with pre-defined acceptance criteria outlined in the product Design Input Summary. A biocompatibility risk assessment determined the following biocompatibility tests are required: - · Cytotoxicity · Hemolysis ### 2.13 SUBSTANTIAL EQUIVALENCE DATA The addition of Tungsten to the Mandrel guidewire family does not change the indications for use of the Mandrel guidewires and is not a change to the fundamental scientific technology. The information summarized above shows the device will perform as well as the previously marketed device. --- **Source:** [https://fda.innolitics.com/submissions/CV/subpart-b%E2%80%94cardiovascular-diagnostic-devices/DQX/K140485](https://fda.innolitics.com/submissions/CV/subpart-b%E2%80%94cardiovascular-diagnostic-devices/DQX/K140485) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
