I've held shares in Ventracor for about 4.5 years. They're the guys behind a 3rd generation artificial heart known as the VentrAssist. Their share price hit some pretty nice highs a few years ago but I didn't sell and now they're down to a point just slightly above where I bought em. From an investment standpoint its a loser - I could have made more just putting the money in ING Direct. But its a company I believe in - one of my lecturers from the biomedical engineering program I dropped out of (hehe) works there, they've got a really elegant product, and IMHO they have a noble goal.
A beautiful data point came recently - a girl whose heart had failed and wasn't eligible for a heart transplant because she also had cancer had a VentrAssist implanted, and after a year her heart had recovered and she's doing fine now with the device removed.
