The CiTop™ guidewire Coronary study is a feasibility open label study, to evaluate the safety and efficacy of the CiTop™ Guidewire for crossing chronic total occlusion in Coronary arteries.

Condition Intervention
Coronary Occlusion
Device: CiTop(tm) Guidewire

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
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 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Successful stenting [ Time Frame: During procedure, Day1, Day7 and Day30 post procedure ] [ Designated as safety issue: Yes ]
  • Wire crossing duration [ Time Frame: during procedure ] [ Designated as safety issue: No ]
  • Fluoroscopy time [ Time Frame: during procedure ] [ Designated as safety issue: Yes ]
  • Amount of contrast [ Time Frame: during procedure ] [ Designated as safety issue: Yes ]
  • Maneuverability of the CiTop™ up to the occlusion [ Time Frame: during procedure ] [ Designated as safety issue: Yes ]
  • No mechanical damage to the device during [ Time Frame: during procedure ] [ Designated as safety issue: Yes ]
