State-of-the-Art Tip Technology

Chronic total occlusions (CTOs) are prevalent, occurring in 20% of patients undergoing percutaneous coronary intervention (PCI),¹ even though these lesions are seriously undertreated.² Fortunately, successful PCIs for CTOs are steadily increasing—despite the increasing complexity of the lesions attempted—due in part to advances in guide wire technology.²

A penetration wire guide wire—the HI-TORQUE INFILTRAC™ Guide Wire, with its CTO indication—is key to successfully penetrating the CTO cap using the antegrade wire escalation (AWE) technique. The design of this specialized guide wire, including its enhanced technology and performance characteristics, all contribute to CTO procedural efficacy and efficiency.

The HI-TORQUE INFILTRAC guide wire, with CTO indication, successfully penetrates the CTO cap.

The HI-TORQUE INFILTRAC™ Guide Wire Designed for CTO Penetration

Micro-Textured Tip: For CTO Passage

This guide wire’s unique micro-textured tip:

  • Provides excellent traction*
  • Can penetrate even resistant proximal CTO caps†

Because the tip is uncoated, it also provides exceptional tactile feedback to the operator.†

The micro-textured tip surface design on the HI-TORQUE INFILTRAC guide wire enables penetration of resistant proximal CTO caps.

Tapered Tip: For High Penetration Capabilities

There are two penetration powers available with the HI-TORQUE INFILTRAC guide wire, used with the antegrade wire escalation technique.

  HI‑TORQUE INFILTRAC™ Guide Wire HI‑TORQUE INFILTRAC™ PLUS Guide Wire
Tip Load* 11 g 14 g
Penetration Power* 167 kg/in² 224 kg/in²

With either choice of guide wire, the tip is tapered to 0.009” to improve penetration capability. In addition to penetration power, the tapered, pre-shaped micro-J tip is a critical feature enabling CTO PCI success.

The HI-TORQUE INFILTRAC guide wires’ tapered tip enables excellent penetration: either 167 kg/in2 or 224 kg/in².


Pre-Shaped Micro-J Tip

The HI-TORQUE INFILTRAC™ Guide Wire’s micro-J tip has a 25° angle extending 1 mm from the tip. This enhances steering to help penetrate CTO lesions.†

The 25-degree angle on the HI-TORQUE INFILTRAC J-tip both aids in steering and enables CTO penetration.


Unique Guide Wire Design

Penetration of challenging CTOs is due to a number of unique design features of the HI-TORQUE INFILTRAC™ Guide Wire:

  • Micro-textured tip to engage the CTO cap*
  • Tapered, pre-shaped tip for high penetration*
  • Uncoated tip for tactile feedback†

Abbott’s proven guide wire design features are also incorporated into the design:

  • DURASTEEL stainless steel for needed support
  • Hydrophilic coating (excluding the tip) for lubricity and ease of movement within a microcatheter
  • Parabolic core grind for excellent torque response
The HI-TORQUE INFILTRAC guide wire incorporates unique features new to this guide wire, as well as proven features of other Abbott guide wires.
