SUNNYVALE, Calif., May 17, 2011 – Asante Solutions, Inc. (Asante), a medical device
company focused on diabetes care, announced that the U.S. Food and Drug
Administration has granted 510(k) clearance for the company’s Pearl Insulin Pump. Last
month, the Pearl also received the CE Mark, a European proof of conformity that certifies
the product meets EU safety, health and environmental requirements.

“We are pleased to accomplish these important regulatory milestones, and we are
particularly proud to be the first fully-programmable insulin pump cleared under the
FDA’s new more comprehensive and stringent infusion pump guidelines,” said Phil
Hopper, Asante’s CEO and president. “These milestones validate our sensible approach
to solving some of the fundamental challenges faced by more than 500,000 people
worldwide who use an insulin pump or are considering insulin pump therapy. These
clearances now allow us to focus on establishing the capabilities necessary to provide
world class operations and customer service as the product becomes available.”

“The Pearl Insulin Pump’s utilization of a pre-filled insulin cartridge is an evolutionary
step forward for those on intensive insulin therapy,” said James Chamberlain, MD,
medical director for Diabetes Services at St. Mark’s Hospital and St. Mark’s Diabetes
Center. “The fact that the Pearl minimizes all the ‘plumbing’ issues associated with
reservoir filling in other insulin pumps makes it an attractive choice as a starter pump for
those initiating insulin pump therapy as well as for those seeking greater ease of use. The
Pearl is designed to reduce steps, add convenience, and save time.”

The Pearl Insulin Pump’s many user-friendly features are designed to make the Pearl an
easy to use system for those on intensive insulin therapy. The pump features a unique
modular product configuration that allows significantly lower pump therapy initiation
costs through pay-as-you-pump pricing. It is the only insulin pump using glass pre-filled
300 unit insulin cartridges for use in pumps for up to seven days. More product details
will be available in the near future at
