Boston Scientific launches endoscopic ultrasound aspiration
24 February 2012
Boston Scientific Corporation has launched 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 is designed with a Nitinol construction
for improved flexibility compared to existing EUS-Fine Needle
Aspiration (FNA) devices and a large diameter for expanded
Endoscopic ultrasound is a non-surgical, less-invasive procedure
that uses high-frequency sound waves to produce detailed images of
the gastrointestinal tract and adjacent organs, including the
pancreas, liver, bile duct and mediastinal space.
To complement EUS, Fine Needle Aspiration (FNA) is often used to
collect tissue samples for cancer diagnosis. Data has shown that
EUS-FNA procedures are associated with improved survival rates for
pancreatic cancer patients due to more informed, stage-appropriate
"High-quality diagnostic samples are critical for accurately
assessing malignancies and choosing the appropriate treatment path
for patients," said Shyam Varadarajulu, MD, Chief of Endoscopy,
University of Alabama at Birmingham, USA. "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. These new features provide an important
advance in EUS-guided diagnosis."
The Expect 19 Flex Needle is made of Nitinol, which offers
improved flexibility and resistance to deformation compared to
traditional stainless steel needles. The echogenic pattern provides
excellent visibility and precise needle guidance within the targeted
organ. As a result, physicians may be able to more easily and
accurately obtain a tissue sample.
"The Expect 19 Flex Needle provides physicians with a clinically
differentiated product designed to help improve patient care," said
David Pierce, President of Boston Scientific's Endoscopy Division.
"This important launch broadens our leading Endoscopy portfolio and
highlights our commitment to delivering advanced technologies to
diagnose gastrointestinal diseases."
