Colorado startup Surefire Medical picked up $16.4 million from 30 investors to support expansion of its operations, according to a report in the Denver Business Journal. The four-year-old startup develops cancer-drug delivering catheters, which are designed to administer treatment directly to tumors through a process called chemoembolization. The device gained FDA approval in 2011 and a CE mark this year. The Journal reports that Surefire offered to sell as much as $21.3 million in equity. Article
