Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor-In-Chief: Priyantha Ranaweera [2];

Key Words and Synonyms: PCI guidewire; angioplasty guidewire; coronary guidewire; steerable wire; steerable guidewire.

Overview

Angioplasty guidewires are small, soft, flexible, lubricated, wires that act as a rail over which equipment such as an angioplasty balloon, a stent, or an intravascular ultrasound device can be delivered over into the coronary artery. Angioplasty guide wires were introduced in 1982 by doctors Simpson and Roberts. The introduction of coronary guidewires was a major advance as it allowed the angioplasty balloon to be a traumatically steered to the proper location.

Guidewire Design Features

A guidewrie has three main components - a core, a tip and a lubricous Coating.

Guidewires Used to Cross Chronic Total Occlusions

Wires to be used in escalating order of aggressiveness:

First Choice

Non-hydrophilic or hydrophobic wires with an intermediate stiffness are a good first choice as they have a better tactile response, are less likely to lead to a subintimal position than a hydrophilic wire, and may have an additional advantage in their ability to cross the proximal cap of the occlusion. Choices in this class include the Miracle Bros 3 and the Asahi intermediate wires.

Second Choice

Hydrophilic wires may track better after the proximal cap of the occlusion has been crossed. Hydrophilic/coated wires have better maneuverability in tortuous or calcified vessels. Intermediate stiffness hydrophilic wire choices include the Choice PT XS (Extra Support), the Pilot 50, the Pilot 100 or the PT Graphix intermediate wire.

Third Choice

Stiff non-hydrophilic wires: The Miracle Bros 6, 9 and 12, Cross-IT, Confienza, Persuader

Fourth Choice

Stiff and hydrophilic (most aggressive): Pilot 200 and Shinobi

Device Delivery Guidewires

Guidewire wiggle wire- The wiggle wire has a niche role in delivering stents and balloons into areas with poor transmission of proximal push. The wiggle wire works by shifting the direction of the pushing forces thus "stepping over" the obstacle.

Peripheral Arterial Guidewires

  • Spartacore - The Spartacore is a peripheral arterial guidewire.
  • Guidewire V 18

Guidewire Tourquing Device

A torquing device is a tool interventional cardiologists use to torque a coronary guidewire and to maintain the tension on the guidewire to preserve the torque and the direction the guidewire. There is a gradual inadvertent “unwinding” of torque when the human fingers are used to steer a coronary guidewire, and this unwinding can be effectively prevented by this tool.
