ASAHI CORSAIR MICROCATHETER Utilization: • Antegrade delivery catheter • Traversing septal perforators • Traversing epicardial collaterals • Ostial purchase

ASAHI CORSAIR MICROCATHETER Manipulation of the Catheter: • Counterclockwise rotation (12 -15 X) to advance • Clockwise rotation (12 -15 X) to withdraw and avoid entrapment • Use with Rotaglide®/Viper. Slide® to enhance wire passage and avoid sumping air • Careful end-hole injections, 5 cc syringe full contrast • Good guide support

Viper. Slide® (Cardiovascular Systems, Inc. , MN) Diamondback Orbital Atherectomy System (soybean oil, egg yolk phospholipids, glycerin and water)
