Key Benefits

  • Atraumatic Bevel Alignment: Precision-ground bevel transition between stylet and cannula minimizes tissue drag.
  • Immediate Backflow Detection: Clear Luer-hub cavity allows instant visual verification of fluid or arterial blood entry.
  • Smooth Guide Wire Passage: Polished inner lumen surfaces ensure snag-free passage of standard 0.018", 0.035", or 0.038" guide wires.
  • High Structural Integrity: Rigid stainless steel construction prevents shaft bending during percutaneous entry through dense tissue.
  • Color-Coded Sizing System: Standardized ISO color coding at the hub allows immediate size identification in fast-paced surgical settings.
