SonoTip® ProFlex EUS FNA Needle System (Nitinol)

A nitinol EUS-FNA needle (nitinol EUS-guided fine needle aspiration needle) takes cells for cytology on a 100% nitinol shaft under endoscopic ultrasound (EUS) guidance, including at extreme scope angles. SonoTip ProFlex is a single-use 22G EUS aspiration needle with a Twist-Lock handle and zig-zag laser engraving that makes the needle read on the ultrasound image.

Frequently asked questions

What is a nitinol EUS-FNA needle?

A nitinol EUS-FNA needle takes cells for cytology under endoscopic ultrasound (EUS) guidance, like any EUS-FNA needle, but its shaft is nitinol instead of stainless steel. SonoTip ProFlex is 22G, 0.7 mm, with a 100% nitinol shaft and a Twist-Lock handle.

What is the difference between ProFlex and ProControl?

Both are EUS-FNA aspiration needles with a Twist-Lock handle. The shaft differs: 100% nitinol on ProFlex, stainless steel on ProControl. ProFlex is 22G, while ProControl comes in 19G, 22G and 25G. ProFlex has a zig-zag laser engraving so that the needle reads on the ultrasound image. ProControl has a specially treated needle and a coloured plastic sheath, which the manufacturer states improve what is seen under endoscopic imaging.

When is a nitinol EUS FNA needle considered, for example at extreme scope angles?

The uses listed on this page are pancreatic head and uncinate targets reached with the scope tip fully angled, hard or fibrotic lesions that need several punctures in one session, and cytology from lymph nodes and submucosal lesions. The choice of needle is the physician's decision.

What are its measurements and guidewire limit?

The needle is 22G, 0.7 mm, with a needle length adjustment of 0 to 8.5 cm and a 1.8 mm sheath. A 2.7 mm version with a distal stabiliser is made for 3.2 to 3.8 mm working channels. The guidewire limit is 0.018 inch.
