A torque device (pin vise) in included with the guide wire to facilitate directional manipulation of the guide wire. An introducer device is included to introduce the guide wire into the catherer or hemostatic valve, and can also be used to shape the tlexible tip of the guide wire, as desired. ## Device Story Micrus Watusi 0.014" guide wire facilitates selective placement of diagnostic or therapeutic catheters within neuro and peripheral vasculature. Device components include flexible proximal shaft, distal atraumatic radiopaque coiled tip, tapered core wire, and hydrophilic coating on distal end. Includes detachable pin vise torque device for directional manipulation and insertion tool/shaping mandrel for tip configuration. Used by physicians in clinical settings; device provides mechanical guidance for catheter navigation. Benefits include improved maneuverability and access to target vasculature. ## Clinical Evidence Bench testing only. ## Technological Characteristics 0.014" diameter guide wire; flexible proximal shaft; distal atraumatic radiopaque coiled tip; tapered core wire; hydrophilic coating on distal end; includes pin vise torque device and shaping mandrel. Mechanical device; no software or energy source. ## 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 - Transend Ex Platinum 0.014 Guide Wire ([K971254](/device/K971254.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

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. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
