Nipro’s Biohole AVF catheter needles are intended for the buttonhole technique, allowing greater patient mobility during treatment. 

Extend the life of the vascular access and reduce pain compared to rope-ladder technique2, 3, 4, 5, 6  thanks to a blunt, siliconized needle.
Biohole AVF catheter needles offer maximum operational efficiency for healthcare professionals and improved quality of life for patients. 

  • Siliconized dull needle reduces pain compared to the rope-ladder technique 1-5  
  • Minimizes potential needling error and hematoma formation 4, 6, 7

  • Less AVF complications: reduces aneurysm formation and only two puncture sites required 4

  • Decreases bleeding time 8-10

  • Safe cannulation during fistula maturation 11

  • Decreased risk of fistula perforation 11

  • Soft and flexible tubing eases the clamping during the bloodline connection/disconnection

  • Preferred option for patients allergic to metal
  • Ultra-thin catheter wall for optimal blood flow 
  • Color-coded hub
  • Latex-free
  • Gamma sterilization
