Another device in me

http://www.atritech.net/animation.html

So I'm told I'm a candidate for a matchman device. This is suppose to reduce my risk of stroke to that of a "normal" person. Stroke is a very scary thing. Yeah, people make fun of it (me included), but seeing my mother with her entire left side paralyzed and watching her live the last 10 years of her life in nursing home makes me want to do everything in my power to prevent this. They want me on blood thinning meds, but I didn't like them. I'm already a slow clotter, and I've have cuts bleed for DAYS on these meds. I'm meeting my doctors at the Mayo in October to review if this is appropriate.
