Many new safety products were introduced, and ICU Medical ( ICUI) established itself as a pioneer in the field. Since launching its first product in 1984 -- a locking system for intravenous lines that prevented accidental disconnection from patients -- ICU Medical has grown substantially, generating high returns on invested capital and lots of cash for shareholders. In 2005, management demonstrated it could reliably turn the fortunes of the company around after a dismal 2004, but the company is ready to bear more fruit from several initiatives that should drive earnings growth for years to come.
