Product Details

True Tip Location. True Tissue Assessment. True Ablation Feedback.

IntellaTip MiFi's Unique Catheter Design
  Tip electrode surface area 30 mm
  Ring electrode surface area 10 mm

Conventional Bi-Poles (CBPs)

  • Capture larger far-field signals
  • Provide an antenna length that extends beyond site of ablation
  • Cannot pace and ablate simultaneously
         ME surface area 0.5 mm

Mini-Electrodes (MEs)

  • Provide more accurate recording of focal area1
  • Allow recording at the precise site of ablation
  • Enable pace capabilities during ablation

True Tip Location: Accurate EGM localization
