Intended Use

The Radifocus® Glidewire® Advantage is designed to direct a catheter to the desired anatomical location during diagnostic or interventional procedures.

Device Story

Radifocus Glidewire Advantage is a manual guide wire used to direct catheters to anatomical targets during diagnostic or interventional procedures. Device consists of a Nickel Titanium alloy core wire with a hydrophilic-coated distal segment and a PTFE-coated proximal segment. Available in various configurations (straight, J-shaped, angled). Operated manually by clinicians in clinical settings. Includes a guide wire inserter to assist insertion into needles or catheters. Facilitates navigation through vasculature to reach target sites for subsequent therapeutic or diagnostic intervention.

Clinical Evidence

Bench testing only. Verification tests included ease of removal from holder, torque control, sliding friction, tip impact, proximal shaft stiffness, and bend strength. Biocompatibility testing performed per ISO-10993 for externally communicating, circulating blood, limited contact devices.

Technological Characteristics

Nickel Titanium alloy core wire; polyurethane and hydrophilic distal coating; PTFE proximal coating. Diameters 0.018"-0.038"; lengths 150-300 cm. Manual operation. Sterilized via ethylene oxide per ANSI/AAMI/ISO 11135-1994 and EN 550 to SAL 10^-6.

Indications for Use

Indicated for directing catheters to desired anatomical locations during diagnostic or interventional procedures. For prescription use only.

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.

## SECTION II. 510(K) SUMMARY

#### A. Device Name

JAN 1 9 2007

| Proprietary Name | Radifocus® Glidewire® Advantage |
|---------------------|---------------------------------|
| Classification Name | Wire, Guide, Catheter |
| Common Name | Guide Wire |

#### B. Intended Use

The Radifocus® Glidewire® Advantage is designed to direct a catheter to the desired anatomical location during diagnostic or interventional procedures.

Note: This is the same intended use as the predicate device - Radifocus Guide Wire K863138

#### C. Device Description

The Radifocus Glidewire Advantage consists of a Nickel Titanium alloy core wire. A polyurethane and hydrophilic coating is applied to the distal portion of the wire while a PTFE coating is applied to the proximal portion. The wire distal segment comes in many configurations such as straight, J shaped, and angled. The wire is package in a plastic holder contained within a pouch. A guide wire inserter is contained within the pouch to assist with the insertion of the wire into a needle or catheter.

#### D. Principle Of Operation / Technology

The Radifocus Glidewire Advantage is operated manually or by a manual process.

#### E. Design / Materials

Differences in materials between the modified device and the predicate device the Radifocus Guide Wire cleared under K863138 raise no new issues of safety and effectiveness.

#### G. Performance

The following verification tests were performed to demonstrate the substantial equivalence of the modified device (Radifocus Glidewire Advantage) to the unmodified device (Radifocus Guide Wire).

- Ease of removal from holder �
- Torque control .
- Sliding friction .
- Tip impact .
- Proximal shaft stiffness ●
- Bend strength ●

None of the data raises any new issues of safety and effectiveness. Additionally, a risk analysis was conducted and there were no new issues of safety and effectiveness.

Therefore the performance of the modified Radifocus Glidewire Advantage is substantially equivalent to the performance of the predicate device the Radifocus Guide Wire which was cleared under K863138.

#### H. Additional Safety Information

Manufacturing controls include visual, functional, dimensional and sterility tests.

Blood contacting materials were tested in accordance with the tests recommended in the FDA General Program Memorandum #G95-1 (5/1/95): Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part-1: Evaluation and Testing".

The guide wire is classified as Externally Communicating Devices, Circulating Blood, Limited Contact (≤ 24 hrs). Results of the testing demonstrate that the blood contacting materials are biocompatible.

Sterilization conditions have been validated in accordance with ANSI / AAMI / ISO 11135-1994, Medical Devices – Validation and routine control of ethylene oxide sterilization and EN 550. The device is sterilized to a SAL of 1056.

Dear Mr. Unterreiner:

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.
