Boston Scientific has announced the global launch of the Expect 19 flex endoscopic ultrasound aspiration needle, used for acquiring tissue samples under endoscopic ultrasound (EUS) guidance for cancer diagnosis in organs adjacent to the gastrointestinal tract.

The Expect 19 flex needle features a Nitinol construction, providing improved flexibility compared to existing EUS-fine needle aspiration (FNA) devices, and a large diameter for expanded diagnostic capabilities.

EUS is a non-surgical, less-invasive procedure that employs high-frequency sound waves to generate detailed images of the gastrointestinal tract and adjacent organs, including the pancreas, liver, bile duct and mediastinal space.

The Expect needle comprises an echogenic pattern enabling physicians to easily and accurately obtain a tissue sample while maintaining visibility during the procedure.

The echogenic pattern of the needle provides visibility and precise needle guidance within the targeted organ, and the cobalt chromium design will offer improved sharpness and pushability, along with deformation resistance, compared to traditional stainless steel needles.

Shyam Varadarajulu, chief of endoscopy at University of Alabama at Birmingham, said: "The improved design of the Expect 19 flex needle allows for access to challenging anatomy and sampling of solid and cystic lesions where traditional needles of this size can’t be used."

"High-quality diagnostic samples are critical for accurately assessing malignancies and choosing the appropriate treatment path for patients," Varadarajulu added.

Boston Scientific Endoscopy Division president David Pierce said: "The Expect 19 flex needle provides physicians with a clinically differentiated product designed to help improve patient care."

"This important launch broadens our leading endoscopy portfolio and highlights our commitment to delivering advanced technologies to diagnose gastrointestinal diseases," Pierce added.

Boston Scientific is a developer, manufacturer and marketer of medical devices that are used in a broad range of interventional medical specialties.
