Boston Scientific Begins U.S. and International Launch of Expect(TM) Endoscopic Ultrasound Aspiration Needle

Innovative Fine Needle Aspiration Technology Expands Diagnostic Capabilities in Pancreas and Gastrointestinal Tract

NATICK, Massachusetts, May 9, 2011 - Boston Scientific Corporation (NYSE: BSX) today announced the
U.S. and international launch of its Expect(TM) Endoscopic Ultrasound
Aspiration Needle, used for acquiring tissue samples for diagnosing and
staging malignancies in organs adjacent to the gastrointestinal tract. The
Expect Needle received FDA clearance and CE Mark approval earlier this year
and is being marketed in the U.S., Europe and other international markets.

Endoscopic ultrasound (EUS) 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 cytology samples for cancer
diagnosis. Data have shown that EUS is associated with improved survival
rates for pancreatic cancer patients due to more informed, stage-appropriate
disease management[1].

"Combining EUS with FNA offers powerful diagnostic
capabilities that can help optimize malignancy management in the GI tract and
inform appropriate treatment paths for the patient, including surgery,
chemotherapy, radiation or palliation," said Robert H. Hawes, M.D., Professor
of Medicine, Division of Gastroenterology and Hepatology, at the Medical
University of South Carolina in Charleston. "The excellent visibility,
sharpness and durability of the Expect Needle help obtain high-quality
diagnostic samples easily and efficiently."

The Expect Needle features an echogenic pattern providing
excellent visibility and precise needle guidance within the targeted organ or
structure. The cobalt chromium design is engineered to offer improved
sharpness and pushability, along with deformation resistance, compared to
traditional stainless steel needles. As a result, physicians may be able to
more easily and accurately obtain a tissue sample while maintaining excellent
visibility during the procedure.

"The quality of tissue samples is critical to accurately
assessing malignancies, which in turn impact treatment algorithms," said
Shyam Varadarajulu, M.D., Director of Endoscopy, University of Alabama,
Birmingham. "The Expect Needle yields detailed, high-quality samples that
enable rapid evaluation of lesions and abnormalities to determine the
specific stage of malignancies."

"The launch of the Expect Needle broadens our Endoscopy
portfolio and further strengthens our leadership position in
pancreaticobiliary disease management," said David Pierce, President of
Boston Scientific's Endoscopy Division. "Providing physicians with an
innovative, durable aspiration needle for EUS-FNA procedures highlights our
commitment to delivering a full suite of advanced technologies to diagnose
gastrointestinal diseases and help improve patient care."
