PLEASANTON, Calif., July 1, 2013 /PRNewswire/ --Thoratec Corporation (NASDAQ:
THOR), a world leader in device-based mechanical circulatory support therapies
to save, support and restore failing hearts, said today it has acquired the
DuraHeart^® II ("DH-II") ventricular assist system from Terumo Corporation
(TSE: 4543 Section 1) for an upfront cash payment of $13 million and potential
future milestone payments, based on regulatory approvals and product sales, of
up to $43.5 million. As part of the agreement, a team of Terumo employees
will transition to Thoratec and will continue to be based in Ann Arbor,
Michigan. Additionally, Thoratec and Terumo have entered into a distribution
partnership, in which Terumo will commercialize DH-II in Japan and potentially
other parts of Asia.

DH-II is an ultra-compact, full-support, centrifugal flow chronic VAD
utilizing a unique technology foundation known as "force balance" suspension.
The device utilizes primary magnetic forces, balanced by hydrodynamic support,
to achieve consistent gaps across the operating range of the pump, independent
of pump speed. This approach is designed to create a pumping mechanism with
excellent blood-handling characteristics. Preclinical testing has shown a
favorable profile for DH-II with respect to hemolysis, bleeding, and

Thoratec intends to apply its resources and expertise in mechanical
circulatory support in order to advance the DH-II program through product
development and clinical trials. Thoratec anticipates a first-in-human
implant of the DH-II pump in 2016 to be followed by clinical trials in the
U.S. and abroad. Following clinical trials, the distribution partnership
between Thoratec and Terumo should optimize patient access to the DH-II
technology on a worldwide basis.

"Thoratec is committed to delivering a steady cadence of innovative new
products to the VAD market in the coming years," said Gary F. Burbach,
President and Chief Executive Officer of Thoratec. "DuraHeart II brings a
differentiated approach to mechanical circulatory support to Thoratec's R&D
portfolio and will be an integral component of our product development
strategy, along with continued evolution of the HeartMate II^® system,
next-generation pump platforms including HeartMate III^TM and HeartMate
PHP^TM, which are expected to begin pivotal CE Mark trials in the second half
of 2013, and breakthrough cross-platform technologies such as our fully
implantable system."

"Terumo believes that the transfer of the development of DuraHeart II to
Thoratec is the best and fastest way to commercialize the technology and to
ensure access for patients in Japan, the U.S., and the rest of the world. We
are pleased that Thoratec recognizes the value of the DuraHeart II platform
and will be applying its expertise and resources to develop and bring this
exciting product to market," said Yutaro Shintaku, President and
Representative Director of Terumo Corporation.

Thoratec anticipates that the acquisition will add incremental ongoing
operating expenses, primarily related to research and development, of
approximately $6-7 million in the second half of 2013. Additionally, Thoratec
will recognize transaction-related expenses, including the amortization of
intangible assets, which will be quantified in the company's second quarter
earnings report and following the completion of the purchase price allocation
for the transaction.
