Rotablator

(Rotational atherectomy)

Blockages in coronary artery arteries may develop build-up of calcium deposits that makes them as hard as concrete. In those cases, your doctor might chose to use the "rotablator" to treat the blockage. The rotablator works like a drill that can spin as fast as 200,000 rpm and can break the calcium build up in very small particles that are re-absorbed by the organism. A coronary stent is usually then inserted.
