Vascular access cannula 13071

Specialized hemodialysis cannula for internal arteriovenous fistula with a dorsal (back‑hole) design and vented lumen to minimize vascular trauma and reduce thrombosis risk.

Key features

• Dorsal back‑hole design with a clinically optimized angle promotes close apposition to the internal fistula vessel wall after puncture, reducing endothelial friction and lowering the risk of long‑term vascular damage during dialysis.
• Back‑hole configuration enables bidirectional blood flow, maintaining stable dialysis blood flow rates and preventing insufficient flow that can impair dialysis efficiency.
• Precision‑ground needle hole edges eliminate burrs, reducing patient discomfort during puncture and minimizing vascular injury and hematoma formation.
• Manufactured from medical‑grade biocompatible material with a vented lumen to reduce blood retention in the cannula and lower thrombosis risk.
