Summary of Atherectomy Devices.

Device	Mechanism	Technical success with PTA ± stent	Complications
Directional atherectomy
Silverhawk (Medtronic) 6-8 Fr	Single-contoured blade, cuts longitudinally on one side		2.5% embolization 5.7% perforation
Turbohawk (Medtronic) 6-8 Fr	Four contoured blades, cuts longitudinally on one side	77% 1-year 1° patency	2.5% dissection
Rockhawk (Medtronic) 6-8 Fr	Additional burr to the solitary blade to cut calcified lesions		SpiderFx for embolization protection recommended
Orbital atherectomy
Diamondback (CSIa) 4-6 Fr	1.25-2 mm crown that spins 360° eccentrically abrading the lesions	93% 1 year 1° patency	3.4% dissection 0% perforation or embolization
Rotational atherectomy
Jetstream (Boston Scientific) 7 Fr	Two sets of rotating stainless steel blades at 70 krpm with an aspiration port aspirating 51 mL/min	62% 1-year 1° patency	1% occlusion, 9% dissection, 10% minor embolization, 2% perforation
Phoenix (Volcano) 5-6 Fr	Rotating blades 1.2 krpm and an Archimedes screw to pull the plaque debris away	94% 30-day 1° patency	1.9% dissection, 0.95% embolization
Excimer laser atherectomy
Turbo-Elite (Spectranetics)	Exciplex phenomena, resulting in photoablation of the plaque	54% 1-year 1° patency	0% occlusion, dissection, embolization, or perforation
