The primary objective of this proposed prospective randomized, multi-center study is to
evaluate the capability of the new 22G SharkCore™ needle to obtain tissue specimens and to
compare its performance against the standard 22G BNX Endoscopic Ultrasound Fine needle
aspiration (Beacon Endoscopic, Newton, MA) needle in the evaluation of solid mass lesions in
the pancreas and gastrointestinal tract. The secondary objective is to determine the ability
of the 22G SharkCore™ needle system to yield histologic tissue.
