Last week had my stent cleaned out, by laser, and now feel much more energetic and ready to tear up the world again. Feel enormous gratitude to people whose work led to stents, lasers, and all that has let me live a decade beyond the age at which my parents died and my genes predicted for me. I signed a permit slip for a new Medtronic stent to be used, experimentally, on me if it were indicated. It wasn't. But that might be a lead to follow for people interested in investing in stent technology.
