Orbital atherectomy for coronary arteries utilises the Diamondback 360° orbital atherectomy system (Cardiovascular Systems) which incorporates a 1.25 mm diamond-coated eccentrically mounted crown that is advanced over a dedicated 0.012″ ViperWire® Advance Coronary Guide Wire (Cardiovascular Systems) with a 0.014″ tip. ViperSlide® (Cardiovascular Systems) lubricant is infused during treatment to reduce friction from a specialised pump that is mounted on an intravenous pole. The crown is controlled by a hand-held electric powered single-use handle that has two speeds for treatment: low (80,000 rpm) and high (120,000 rpm). The orbital atherectomy system is compatible with a 6 Fr or larger catheter.

Employing centrifugal forces, the 1.25 mm crown orbits as it advances through a coronary artery, allowing for the continuous flow of blood during atheroablation. ...
