The EUS-FNA is used to derive tissue or cell samples from lesions for definitive pathology diagnosis.

The EZ Shot 3 needle is instrumental in certain EUS-FNA cases when it is required to be inserted into difficult-to-access locations, such as in the pancreatic head which can otherwise only be reached with a high-degree of curvature in the tip of the endoscope.

The sheath’s multi-layer construction reduces friction with the needle allowing it to make its way smoothly.

It is composed of Nitinol, which offers flexibility and allows the needle to retain its straight shape even after making multiple passes.
