INDICATIONS FOR USE
This Hi-Torque Guide Wire is intended to facilitate the placement of balloon dilatation catheters during percutaneous transluminal angioplasty (PTA), in arteries such as the femoral, popliteal and infra-popliteal arteries. This guide wire may also be used with compatible stent devices during therapeutic procedures.
The guide wire may also be used to reach and cross a target lesion, provide a pathway within the vessel structure, facilitate the substitution of one diagnostic or interventional device for another, and to distinguish the vasculature.
CONTRAINDICATIONS
Not intended for use in the coronary or cerebral vasculature.
WARNINGS
This device is not designed for use with atherectomy devices.
This device is designed and intended for ONE-TIME USE ONLY. Do not resterilize and / or reuse.
Carefully observe the instructions under “Do Not” and “Do” below. Failure to do so may result in vessel trauma, guide wire damage, guide wire tip separation, or stent damage. If resistance is observed at any time, determine the cause under fluoroscopy and take remedial action as needed. Use the most suitable guide wire for the lesion being treated.
Do Not:
• Push, auger, withdraw, or torque a guide wire that meets excessive resistance. • Torque a guide wire if the tip becomes entrapped within the vasculature. • Allow the guide wire tip to remain in a prolapsed condition. • Deploy a stent such that it will entrap the wire between the vessel wall and the stent.
Do:
• Advance or withdraw the guide wire slowly. • Use the radiopaque marker of the interventional device to confirm position. • Examine the tip movement under fluoroscopy before manipulating, moving, or torquing the guide wire. • Observe the wire under fluoroscopy for tip buckling, which is a sign of resistance. • Maintain continuous flush while removing and reinserting the guide wire to prevent air from entering the catheter system. Perform exchanges slowly to prevent air entry and / or trauma.• When reintroducing the guide wire, confirm that the interventional device tip is free within the vessel lumen and that the tip is parallel to the vessel wall. • Use extreme caution when moving a guide wire through a non-endothelialized stent, or through stent struts, into a bifurcated vessel. Use of this technique involves additional patient risks, including the risk that the wire may become caught on the stent strut.
PRECAUTIONS
Guide wires are delicate instruments and should be handled carefully. Prior to use and when possible during the procedure, inspect the guide wire carefully for bends, kinks, or other damage. Do not use damaged guide wires. Using a damaged guide wire may result in vessel damage and / or inaccurate torque response.
Confirm the compatibility of the guide wire diameter with the interventional device before actual use.
Free movement of the guide wire within the interventional device is an important feature of a steerable guide wire system, because it gives the user valuable tactile information. Test the system for any resistance prior to use. Adjust or replace the hemostatic valve with an adjustable valve if it is found to inhibit guide wire movement.
Never attach the torque device to the modified portion of the proximal end of the extendible guide wire; otherwise, guide wire damage may occur, preventing the ability to attach the DOC Guide Wire Extension.
Avoid abrasion of the hydrophilic coating.
Do not withdraw or manipulate the hydrophilic-coated wire through a metal cannula or sharp-edged object.
