The Asahi Intecc PTCA Chronic Total Occlusion Study

"Standard angiographic procedures will be followed for this study. The primary objective of this trial is to evaluate confirmation of placement of any guidewire beyond the chronic total occlusion (CTO) in the true vessel lumen in patients in which at least one Asahi series of guidewires and/or Corsair microcatheter were used.~Procedure success will be defined as angiographic visualization of any guidewire in a position either distal or proximal to the occlusion depending on the route of access and the absence of in-hospital MACE.~Other Name: ASAHI Corsair Microcatheter, ASAHI PTCA Guide Wires"
