Primary Purpose: Treatment
Official Title: A Feasibility Study to Evaluate the Safety and Efficacy of the CiTop™ Guidewire for Crossing Chronic Total Occlusion in Coronary Arteries

Further study details as provided by Ovalum:

Primary Outcome Measures:
  • Angiographic documentation of placement of CiTop™ distal to occlusion with no device related major complications. [ Time Frame: during procedure, 1day, 1week and 30 days post procedure ]

Secondary Outcome Measures:

  • Wire crossing duration [ Time Frame: during procedure ]
  • Fluoroscopy time [ Time Frame: during procedure ]
  • Amount of contrast [ Time Frame: during procedure ]
  • Maneuverability of the CiTop™ up to the occlusion [ Time Frame: during procedure ]
  • No mechanical damage to the device during [ Time Frame: during procedure ]
