The medical device maker said it has notified 60 employees that their jobs were being moved to Wisconsin and California.

Medical device maker Cardiac Science of Bothell, which employed more than 125 before its January 2011 sale to Opto Circuits of India, will wind down most of its remaining local operations by September.

The company notified 60 people this week that their jobs are being transferred to company sites in Wisconsin and California, said CEO Bob Odell in a phone interview from its Deerfield, Wis., manufacturing plant.

Cardiac laid off about 50 others last summer, a few months after Opto bought the former public company for $55 million.

Odell said Cardiac will retain about 10 people here doing advanced research, but probably not at the current Bothell location.

He said the consolidation is a matter of efficiency because “the other facilities have hundreds of people.” The bulk of the Bothell jobs — in areas such as regulatory affairs, marketing, and IT — will go to Wisconsin, and few of the local employees showed interest in moving there, he said.

Cardiac Science makes automated external defibrillators for reviving people in cardiac arrest, as well as testing and rehabilitation equipment for heart patients. Opto makes a variety of medical equipment.
