Intended Use

The IQ ™ Guide Wires are intended to facilitate the placement and exchange of balloon dilatation catheters or other therapeutic devices during PTCA or PTA or other intravascular interventional procedures. The IQ ™ Guide Wires are not intended for use in the cerebral vasculature. The devices are provided non-pyrogenic, sterile, and intended for one procedure only.

Device Story

IQ Guide Wire is a steerable, spring-coil guide wire used by physicians during intravascular interventional procedures (PTCA, PTA). Device facilitates placement and exchange of balloon dilatation catheters or other therapeutic devices. Features include 0.014-inch diameter, 185cm or 300cm lengths, floppy tip, and moderate support rail. Distal end is radiopaque with straight or J-tip options; optional lesion length marker system available. 185cm version includes proximal extension for connection to AddWire Extension Wire. Device is silicone-coated. Used in clinical settings; operated by physicians. Output is physical guidance of catheters through vasculature. Benefits include improved navigation and exchange of interventional tools during procedures.

Clinical Evidence

Bench testing only. Evaluation included torque response, tip prolapse, tip shapeability, radiopacity, marker location, lubricity, coating adherence, tensile and shear strength, combined load, visual inspection, device compatibility, biocompatibility, and shelf-life. Results verified device met all minimum requirements.

Technological Characteristics

Silicone-coated, steerable, spring-coil guide wire. 0.014-inch diameter; 185cm/300cm lengths. Full-length outer spring coil with inner coil. Distal radiopaque tip (straight or J-shape). Optional marker coils. Non-pyrogenic, sterile. No software or energy source.

Indications for Use

Indicated for facilitating placement and exchange of balloon dilatation catheters or other therapeutic devices during PTCA, PTA, or other intravascular interventional procedures. Not for use in cerebral vasculature.

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.

| Intended Use of Device | The IQ ^™ Guide Wires are intended to facilitate the placement and exchange of balloon dilatation catheters or other therapeutic devices during PTCA or PTA or other intravascular interventional procedures. The IQ ^™ Guide Wires are not intended for use in the cerebral vasculature. The devices are provided non-pyrogenic, sterile, and intended for one procedure only. |

| Technological Characteristics | The IQ ^™ Guide Wires utilize similar materials and methods of construction as the IQ ^™ Hydrophilic Guide Wires (K032183, August 01, 2003). The main differences in construction are the full-length outer spring coil with an inner coil instead of a spring tip and polymer sleeve, and silicone coating instead of hydrophilic coating. The IQ ^™ Marker version also has marker coils, which the IQ ^™ Hydrophilic does not. |
| Non-Clinical Test Summary | Testing and evaluation of the IQ ^™ Guide Wires included torque response, tip prolapse, tip shapeability, radiopacity, marker location, lubricity, coating adherence/presence, tensile and shear, combined load, visual inspection, device compatibility, biocompatibility, and product shelf-life. <p> Test results verified that the IQ ^™ Guide Wires met all of the minimum requirements and are adequate for their intended use. </p> <p> The IQ ^™ Guide Wires are considered substantially equivalent to guide wires currently marketed by Boston Scientific based on a comparison of intended use, design and the results of <i>in vitro</i> testing and evaluation. </p> |
