Hi-Torque Winn™ .014

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 resistance.
• Torque a guide wire if the tip becomes entrapped within the vasculature.
• Allow the guide wire tip to remain in a prolapsed condition.

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 Winn™ family only: The Winn™ family of guide wires have distal ends of varying stiffness. Operate these guide wires carefully so as not to 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.
