3M Co. drove home the message of its newly launched 3M Science brand Friday with news that it has completed purchasing Ivera Medical Corp. Terms were not disclosed.

Ivera, the San Diego-based manufacturer of health care products that disinfect IVs and catheters, is now a subsidiary of 3M. The entity, which generates about $30 million a year and has 60 employees, will become part of 3M's critical and chronic care solutions division.

The acquisition is expected to blend well with 3M's existing line of vascular access products, which also include IVs and catheters.

Ivera expands 3M's offerings to hospitals and clinics, locations where infection control is increasingly important and frequently problematic.

News of the Ivera acquisition came Friday, the same day 3M officially launched its new brand and advertising campaign, which carries the tagline, "3M Science. Applied to Life."

The campaign will use Twitter, Facebook and other online outlets to spread the message that it uses science to create new products and solve customers' problems.

The campaign was launched online and at the South by Southwest festival, which began Friday in Austin, Texas.
