Vital Access

The VWING Vascular Needle Guide by Vital Access Corporation received FDA market clearance in 2013. It enables reliable and consistent needle access to arteriovenous fistulas for hemodialysis patients. Clinical studies cited by the company suggest improved long-term durability and patency of AV fistulas using this device, especially with the buttonhole cannulation technique. The product has also been approved for use in Europe and Canada. "The VWING provides an easily palpable target for needle insertion and guides a dialysis needle directly to the targeted vessel... Buttonhole cannulation technique has been shown in multiple clinical studies to reduce AV fistulae complications and improve long-term fistula durability and patency." No recent clinical trial data or new products are reported.
