@SailorJerry - I think they're different. Angioplasty is done with something called a balloon catheter. It goes in on guidewires and then the balloon inflates to get the plaque out of the way, as opposed to with a Fogarty catheter which inflates just to stay in place.
Now, what I hope someone can explain is the difference between a Foley catheter and a Fogarty, because they sound really similar. I had a Foley catheter when I was in labor; I think that's what they usually use to drain urine. (I kept trying and just couldn't get any urine out. Then I had an epidural and finally a C-section, so I would have needed it anyway.)
Foley vs. Fogarty, anyone? It sounds like they both have balloons.
