Do Not:

• Push, auger, withdraw, or torque a guide wire that meets 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.

• Consider that if a secondary wire is placed in a bifurcation branch, this wire may need to be retracted prior to stent deployment, because there is additional risk that the secondary wire may become entrapped between the vessel wall and the stent.

For the HI-TORQUE PROGRESS™ family only: The HI- TORQUE PROGRESS™ family of guide wires has distal ends of varying stiffness. Operate these guide wires carefully so as to not injure the blood vessel, observing the information in these instructions. The higher torque performance, stiffer distal ends, and / or higher advancement force may present a higher risk of perforation or injury than a guide wire with a more pliable distal end. Therefore, use the guide wire with the least stiff distal end that will treat the lesion, and use extreme care to minimize the risk of perforation or other damage to blood vessels.

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.

Refer to the device label for any additional product-specific contraindications which may apply.

WARNINGS
This device is designed and intended for ONE-TIME USE ONLY. DO NOT RESTERILIZE AND / OR REUSE.

Observe all guide wire movement in the vessels. Before a guide wire is moved or torqued, the tip movement should be examined under fluoroscopy. Do not torque a guide wire without observing corresponding movement of the tip; otherwise, vessel trauma may occur.

Torquing a guide wire against resistance may cause guide wire damage and / or guide wire tip separation. Always advance or withdraw the guide wire slowly. Never push, auger, withdraw or torque a guide wire which meets resistance. Resistance may be felt and / or observed under fluoroscopy by noting any buckling of the guide wire tip. Determine the cause of resistance under fluoroscopy and take any necessary remedial action.

If the wire tip becomes entrapped within the vasculature, DO NOT TORQUE THE GUIDE WIRE.

Maintain continuous flush while removing and reinserting the guide wire to prevent air from entering the catheter system. Perform all 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 not against the vessel wall. Failure to do so may result in vessel trauma upon guide wire exit of the device. Use the radiopaque marker of the interventional device to confirm position.

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 wires. Using a damaged 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. Test the system for any resistance prior to use. Mild to moderate resistance may be felt as the HI-TORQUE WIGGLE™ Guide Wire waves are advanced or retracted through the catheter. If severe resistance is encountered, it may be necessary to change to a catheter having a larger guide wire lumen.

Never attach the torque device to the modified portion of the proximal end of the extendable guide wire; otherwise, guide wire damage may occur, preventing the ability to attach the DOC™ Guide Wire Extension.

ADVERSE EVENTS
Potential Adverse Events associated with use of this device may include the following but not limited to perforation, dissection, occlusion, myocardial infarction, embolism and infection.

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.

Please refer to the indication on the label and the Instructions for Use to confirm the appropriate vasculature that this guide wire may be used in. Failure to abide by the above recommendation may result in size mismatch of blood vessel and guide wire, which can result in vessel injury, such as, but not limited to, perforation, dissection, rupture, and avulsion.

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. It is recommended that the user determine the source of resistance, exercise caution when removing the device and/or other components as a unit and exchange the device for a new one to complete the procedure.

Never attach the torque device to the modified portion of the proximal end of the extendable 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. Manipulation, advancement, and/or withdrawal through a metal device may result in destruction and/or separation of the outer coating, which may cause coating material to remain in the vasculature. This in turn may lead to unintended adverse events requiring additional intervention.

When wet, a hydrophilic coating increases the lubricity of the guide wire surface.

Do not soak the device for longer than 4 hours when the device is not in use. Avoid pre-soaking devices for longer than instructed, as this may impact the coating performance.

The coating swells when exposed to aqueous media, but does not have any impact on the device use.

The integrity and performance of the device coating can be negatively impacted by preparation with incompatible media or solvents. Please take note of the following important recommendations:

• Avoid wiping the device with dry gauze as this may damage the device coating.
• Avoid excessive wiping of the coated device.
• Avoid using alcohol, antiseptic solutions, or other solvents (e.g., use of medications and rotoflush) to pre-treat the device because this may cause unpredictable changes in the coating which could negatively affect the safety and performance of the guide wire.

Attempting to alter the shape of the devices by bending, twisting, or similar methods beyond instructed methods may compromise the coating integrity, and that damage to the coating may not always be noticeable to the naked eye.
