         JUNE 17, 2004, SAN CLEMENTE, CALIFORNIA --ICU Medical, Inc.,
(NASDAQ/NMS:ICUI), a leading low cost manufacturer of safe medical connectors
and custom intravenous systems, today announced that it has filed a patent
infringement action against Alaris Medical Systems, Inc., a California-based
medical products Company. ICU Medical filed the lawsuit after the United States
Patent and Trademark Office issued a Certificate of Correction on June 15, 2004
for United States Patent No. 6,682,509, owned by ICU Medical. The lawsuit, filed
on June 16, 2004, in United States District Court for the Central District of
California asserts that Alaris is infringing the 6,682,509 patent in the
manufacture and sale of the SmartSite and SmartSite Plus Needle-Free Valves and

Certificate of Correction. ICU Medical seeks a temporary restraining order and
preliminary and permanent injunction against Alaris, treble damages, attorney's
fees, costs and expenses.
