Device Story

Nitinol (nickel-titanium alloy) guidewire; distal tip features helically coiled gold-plated tungsten wire; surface coating facilitates smooth passage. Used by clinicians in peripheral and coronary vasculature procedures to assist in catheter placement. Device provides mechanical support and navigation through vascular anatomy. Benefits include improved trackability and access to target vessels.

Clinical Evidence

Bench testing only. Dimensional inspection conducted with acceptable results; verification/validation testing confirmed modifications do not impact original device performance.

Technological Characteristics

Materials: Nitinol (nickel-titanium alloy) core, gold-plated tungsten wire distal coil. Surface coating applied. Dimensions: 0.014", 0.016", 0.018", 0.025", and 0.035" diameters. Mechanical device; no energy source or software.

Indications for Use

Indicated for use in peripheral vasculature (0.035", 0.025", 0.014", 0.016", 0.018" diameters) and coronary vasculature (0.014", 0.016", 0.018" diameters).

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 Ms. Anderson:

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.

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.
