Canaan Partners, a global venture fund with $3.5 billion under management, has raised $600 million to invest in technology and health-care companies. Canaan, based in Menlo Park, California, will spend two- thirds of the fund on digital media, Internet, mobile and other technology companies, and a third is designated for pharmaceutical, medical device and health-care investments, the company said today in a statement. This is Canaan’s ninth fund. Previous investments included Advanced BioHealing Inc., maker of Dermagraft, a bio-engineered skin substitute used to treat diabetic foot ulcers, which was acquired by Shire Plc in May for $750 million, and flash storage maker SandForce Inc., was acquired by LSI Corp. for $370M earlier this month.
