> OrbiMed Advisors has raised $550 million for its new health venture fund, its largest ever, according to VentureWire. More than half of that money will be used to invest in biotech companies with 30 percent reserved for medical devices and 10 percent for diagnostics. OrbiMed has been an active player in the biotech space, backing CoGenesys, Cerexa and Peninsula, which all sold for a premium. Altogether the venture group expects to use the money to take stakes in 25 to 30 companies. OrbiMed release
