Device includes a torque device for manipulation and a guidewire introducer for catheter hub/hemostasis valve insertion. Used by clinicians in clinical settings for selective catheter placement in peripheral, visceral, and cerebral vasculature. Operates as a mechanical guide to facilitate navigation through the vascular system during diagnostic or therapeutic procedures. ## Clinical Evidence Bench testing only. Biocompatibility verified per ISO 10993-1 for external communicating, blood contact, short duration (<24 hrs) device. In-vitro performance testing included dimensional inspection, tensile strength, torque strength, flexibility, trackability, particulate, and catheter compatibility. ## Technological Characteristics Stainless steel guidewire with radiopaque platinum distal coil. Hydrophilic coating on distal portion and proximal 30cm. Includes torque device and introducer. Biocompatibility per ISO 10993-1. ## 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 - Micro Therapeutics, Inc. .010" SilverSpeed™ Hydrophilic Guidewire - B.

(949) 837-3700 | #### Predicate Devices Micro Therapeutics, Inc. . 010" SilverSpeed™ Hydrophilic Guidewire B. Braun Guidewire Introducer & Guidewire Torque Device #### Device Description The SilverSpeed™ Hydrophilic Guidewire is a stainless steel guidewire with a radiopaque platinum distal coil. The guidewire is hydrophilically coated from the shapeable platinum coil up to the proximal 30cm of the guidewire. Included within the sterile pouch is a torque device to assist in guidewire manipulation and a guidewire introducer to ease the introduction of the guidewire into the catheter hub and/or hemostasis valve. #### Intended Use The guidewire is indicated for general intravascular use to aid in the selective placement of catheters in the peripheral, visceral and cerebral vasculature during diagnostic and/or therapeutic procedures. #### Testing Biocompatibility of the guidewire has been verified in accordance with ISO 10993-1, Biological Evaluation of Medical Devices. Test results confirmed biocompatibility of the guidewire when tested as an external communicating, blood contact, short duration (<24 hrs.) device. In-vitro performance testing of the guidewire included dimensional inspection, tensile strength, torque strength, flexibility, trackability, particulate and catheter compatibility tests. All testing of the product yielded acceptable results substantially equivalent to the predicate device. #### Summary of Substantial Equivalence The SilverSpeed Hydrophilic Guidewire and accessories are substantially equivalent to the predicate device in intended use and principle of operation. {1}------------------------------------------------ Image /page/1/Picture/1 description: The image shows the seal of the Department of Health & Human Services (HHS) of the United States of America.
