Orbital Atherectomy

Orbital Atherectomy is a minimally invasive procedure that uses a rotating, diamond-coated crown on a catheter to grind away hardened plaque in arteries. This "sanding" of calcium deposits makes the artery more pliable, allowing for a stent to be placed more effectively and improving blood flow. It is used to treat calcified blockages in both coronary and peripheral arteries, often before a stent is deployed.
