資訊

Double Lumen RX Microcatheter

  • Lotus technologies provide stability and greater certainty for percutaneous coronary intervention.
  • Kink resistance: Double stainless steel core maintains high kink resistance as well as increasing pushability.
  • Precise, reliable guide wire control and easy recognition of the guide wirefrom OTW lumen exit port.

Single Lumen Microcatheter

  • Progresses easily in chronic total occlusions and vascular stenosis with its atraumatic tip structure and hydrophilic surface. 
  • Compatible with wires of 0.018” and smaller diameters.
  • Enhanced resistance to kinking in tortuous anatomy.
  • Facilitates optimal guide wire performance.

Single Lumen & Double Lumen Options
  • Single Lumen: Simplified wire tracking, ideal for straightforward coronary access and lesion crossing.
  • Double Lumen: Facilitates dual-wire or over-the-wire techniques, supporting complex, tandem lesions or bridging occlusions.
  • Reinforced Microbraiding: Offers enhanced pushability and torque control, ensuring stable wire support in heavily calcified or tortuous coronary anatomies.
  • Minimal Kink Susceptibility: Maintains lumen patency even under high angulation or multiple wire manipulations.
  • Low-Friction Surface: Reduces friction during lesion crossing and device exchanges, lowering the risk of vessel trauma.
  • Improved Navigability: Ensures smooth movement within tight or heavily calcified lesions, aiding device guidance.
  • Fluoroscopic Visibility: A marker between shaft and tip clearly delineates microcatheter tip position under x-ray, ensuring safe and accurate lesion engagement.
  • Distal Coil Reinforcement: Provides tip stability and radiopacity, ensuring reliable guidance through challenging lesion channels.
  • Precise Steering: The torque-friendly design supports rotational control, allowing clinicians to fine-tune tip orientation and tackle eccentric or bifurcated lesions.
  • Maximized Push Efficiency: Helps in crossing chronic total occlusions (CTOs) where greater torque and penetration force are crucial.
