I know the FDA hasn't aproved them yet, but many places are doing them. I just went to an excellent seminar, and they talked about them quite a bit. The scary thing was, after every procedure they would open up the distal protection device, and show you what it had stopped. To say the least, it was pretty scary thinking that the reeains in the distal protection device were actually potential strokes. It made me really stop and think about other embolisms we cause with angioplasties/stents.
