San Clemente-based medical device maker Cameron Health Inc. is being bought by Boston Scientific Corp. for $150 million in cash, with additional payments of up to $1.05 billion possible based on future milestones.
Cameron makes the S-ICD System implantable heart defibrillator, which is under review by the Food and Drug Administration.
Natick, Mass.-based Boston Scientific said it anticipates regulatory approval for S-ICD in the first half of 2013. The device has been sold in Europe and other overseas markets since 2009.
Boston Scientific has been a Cameron investor since 2004, and it held an option to buy the company.
Cameron has raised nearly $200 million in venture funding since it started 10 years ago.
