Robert Goldman had been a successful Internet age inventor having developed some of the critical technology underlying the way digital music is stored, searched, and purchased online. But when his sister developed cancer, he found himself turning his skills as an inventor into an unchartered area for him. Eventually he developed a new type of catherter to deliver cancer medicines directly to where they are needed in the body. But despite his company’s success at winning marketing clearance from the U.S. Food and Drug Administration, his company Vascular Designs has had difficulty raising money. On October 17 Vascular Designs launched a campaign to raise $500,000 through the crowdfunding site Indigogo. We spoke to Goldman about his IsoFlow catheter, the funding environment for innovative medical device companies, and his decision to turn to crowdfunding.
