FineDuo® - Multifunctional dual-lumen microcatheter

Maintains manoeuvrability

  • Dual Lumen configuration avoids tangling of guidewires and improves guidewire manipulation1
  • Design at OTW lumen exit port generates greater rotation range for the guidewire7
  • Robust proximal shaft maintains its stability and manoeuvrability7,8

Achieves superior crossability

  • Double radiopaque markers for accurate placement, including a 1mm marker on RX lumen for clear visualization of the distal tip
  • Low profile, tapered flex tip and hydrophilic coating with strong back-up force provides superior trackability and crossability2,8
  • Stronger penetration force compared to a conventional microcatheter8
