What It Is

The Hi-Torque Balance Guide Wire is a specialized guide wire used in interventional cardiology. It features a hydrophilic coating that enhances its ability to navigate through blood vessels with reduced friction. This device is crucial for procedures requiring precise navigation and placement of catheters, such as angioplasty.

FDA-Cleared Indications

  • Used to guide and position catheters within blood vessels during intravascular procedures.
  • Intended for use with compatible catheter systems when vascular access and catheter navigation are required.
  • The product code identifies it as a catheter guide wire under 21 CFR 870.1330.

Clinical Applications

  • Guiding diagnostic or therapeutic catheters through the vascular system.
  • Facilitating catheter placement during coronary catheterization and percutaneous coronary intervention when consistent with the device labeling.
  • Supporting placement of balloon or stent-delivery catheters in appropriately selected vascular procedures.
  • Navigating tortuous or difficult vascular anatomy with a hydrophilic-coated guide wire.

Reported off-label uses

  • Guide-wire support for selected peripheral vascular interventions when the specific product labeling does not identify that vascular territory.
  • Use in other endovascular procedures requiring catheter navigation, when selected and handled by an appropriately trained clinician.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Practical Considerations

  • Available guide-wire diameter and length should match the target anatomy, access route, catheter system, and procedural objective.
  • The hydrophilic coating becomes lubricious when properly wetted; follow the product instructions for preparation, flushing, handling, and storage.
  • Use only with compatible catheters and equipment. Do not force advancement or withdrawal if resistance is encountered, because vessel injury or wire damage can occur.
  • MRI safety depends on the exact product configuration and current manufacturer labeling. Confirm MR status before exposing the wire or any retained component to an MRI environment.
  • Potential complications include vessel spasm, dissection, perforation, thrombosis, embolization, infection, wire fracture, and bleeding. Contraindications and warnings should be reviewed in the current instructions for use.
