I think ideas are so easy to come up with. They’re the easiest thing. It's the implementation and it's a long road. Whenever you launch a company, it's a six- or seven-year journey if you're successful. I spent a lot of time early, and I'm willing to kill these ideas if they don't meet the criteria. So why don't you tell us a little story? I want to hear about at least the process that typically happens and maybe the timeframe for one of these ideas. Let's take one that's a success from idea to actually some exit and the hurdles along the way. These ideas come in random and multiple ways. So back in 1992, a friend of mine had a carotid endarterectomy, which is a cleaning up of carotid arteries, and ended up with a stroke, and he had then a few months later, the second carotid artery cleaned and he had another stroke. I started scratching my head and I said, "These are embolic events and there should be a way to fix that or prevent that from happening." I was busy with a couple of other companies so it was in the back of my mind. Then, another year later, another acquaintance of mine had a saphenous vein graft angioplasty and ended up dying because of a huge amount of embolic load flowing downstream into the heart. So that really was the beginning of the concept. So I said, "This is a problem that's worth fixing." So I went to some of my friends who were interventional cardiologists, folks here and at other institutions. I said, "Is this a problem in your practice?" They said, "No, we never have embolic events when we're doing stenting or angioplasty." So I started looking at literature and what I found, sure enough, in the U.S., clinical literature, back in the early -90s, couldn't find any papers talking about embolic events and complications, but Europeans were writing about it. They're not worried about getting sued. Always, when you're looking at some unique problems, look at European literature. Sometimes, they're much more open ...
