Expect™ and Expect Slimline (SL)

Endoscopic Ultrasound Aspiration Needles

Physician preference matters. That's why we offer choices for handle size and shape, actuation/tactile feel, flexibility and durability of the needle.1 All needles have a highly visible echogenic pattern and a sharp needle tip grind.

Product Details

Understanding your need to obtain core material for advanced testing, we developed a 19ga needle made of Nitinol, the Expect 19ga Flexible Needle. Compared with the current Expect 19ga Cobalt-Chromium Needle, the Expect 19ga Flexible Nitinol Needle can offer flexibility and durability for increased utility in more tortuous applications and anatomies.

The Nitinol Difference

  • Nitinol construction provides flexibility, passability and actuation comparable to the 22ga Expect1
  • Nitinol is more resistant to needle deformation through tortuous anatomy compared to stainless steel*

Custom Needle Grind for Improved Sampling

  • Sharp grind and deep needle bevel help provide precise penetration into the target area and the potential for improved tissue sampling
