Intended Use

GT2 Fusion Guide Wires are steerable guide wires that are used for the introduction and placement of diagnostic or interventional devices in the coronary and peripheral vasculature and may be used to reach and cross a target lesion. The GT2 Fusion Guide Wires are not intended for use in the cerebral vasculature. GT2 Fusion steerable exchange wires are used to facilitate the substitution of one diagnostic or interventional device for another.

Device Story

Steerable guide wire for coronary and peripheral vascular procedures; facilitates introduction/placement of diagnostic or interventional devices and device exchange. Components: hypotube, core wire, spring, forming member. Features: .014" diameter; 180cm/300cm lengths; straight or J-tip; PTFE or hydrophilic coatings. Operated by physicians in clinical settings to navigate vasculature and cross lesions. Output is mechanical guidance for interventional tools. Benefits: enables precise delivery of diagnostic/therapeutic devices to target vascular sites.

Clinical Evidence

Bench testing only. In-vitro performance testing included dimensional inspection, tensile strength, torque strength, coating adhesion and durability, tip whip, tip stiffness, and distal trackability. Biocompatibility testing performed on device materials.

Technological Characteristics

Components: hypotube, core wire, spring, forming member. Coatings: PTFE or hydrophilic. Dimensions: .014" diameter, 180cm/300cm lengths. Tip: straight or J-tip. Mechanical device; no energy source or software.

Indications for Use

Indicated for introduction and placement of diagnostic or interventional devices in coronary and peripheral vasculature; used to reach and cross target lesions. Not for use in cerebral vasculature. Used for device exchange.

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.

Predicate Devices

• Medtronic GT1 Guide Wire (K983927)
• Bard Hydrophilic Coated Guide Wire (K974713)
• USCI Commander Series Guide Wires (K961271)

## 510(k) SUMMARY OF SAFETY AND EFFECTIVENESS (Pursuant to Section 12, Safe Medical Devices Act of 1990) 7/1/99

- Medtronic, Inc. Submitted by: 1. 37 A Cherry Hill Drive Danvers MA 01923
- Fred Boucher 2. Contact Name: Regulatory Affairs Manager [phone]
- Medtronic® GT2 Fusion Guide Wire. Trade or Proprietary Name: 3. Common/Classification Name: Catheter Guide Wire Name of Predicate Device: AVE GT1 Guide Wire Classification: Class II These wires will be available in: .014" diameter 180cm & 300 cm in length Straight and "J" tip configurations PTFE coating with Pro/Pel coating and PTFE coating with hydrophilic coating on the distal 60 cm.
- GT2 Fusion Guide Wires are steerable guide wires that are used for the introduction and placement of 4 diagnostic or interventional devices in the coronary and peripheral vasculature and may be used to reach and cross a target lesion. The GT2 Fusion Guide Wires are not intended for use in the cerebral vasculature. GT2 Fusion steerable exchange wires are used to facilitate the substitution of one diagnostic or interventional device for another.
- 5 The major components of the device include the hypotube, core wire, spring, and forming member. The Medtronic® GT2 Fusion Guide Wire is similar in performance to the predicate devices.
- б All appropriate biocompatibility tests, with the exception of sensitization, which will be available on July 12, 1999, were successfully performed on the materials used for the Medtronic® GT2 Fusion Guide Wires.
- 7 In-vitro performance testing of the guidewire included dimensional inspection, tensile strength, torque strength, coating adhesion and durability, tip whip, tip stiffness and distal trackability. Test results verified that the Medtronic® GT2 Fusion Guide Wires meet all of the applicable specifications and are deemed adequate for the intended use. The Medtronic™ GT2 Fusion Guide Wire is considered to be substantially equivalent to the following devices:
- . Medtronic GT1 Guide Wire (K983927)
- . Bard Hydrophilic Coated Guide Wire (K974713)
- . USCI Commander Series Guide Wires (K961271)

Dear Mr. Boucher:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 A substantially equivalent determination assumes compliance to 895. with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Requlation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
