Safety & Performance Randomized Study of the CiTop™ Guidewire for Peripheral CTO

Not Applicable

Terminated

• Conditions: Catheterization, Peripheral
• Interventions: Device: CiTop(TM) Guidewire

• Registration Number: NCT00482742
• Lead Sponsor: Ovalum

Brief Summary

The main objectives of the study are:

To evaluate the performance and safety of the CiTop guidewire, while attempting to cross thru total occlusions of various dimensions and morphology.

To compare the safety and efficacy of the CiTop guidewire with standard guidewires in terms of impact on the treated artery. Following operation of the CiTop device, angiography demonstrated successful crossing of the occlusion with no visible evidence of arterial wall injury, dissection, or distal embolization.

To assess ease of operation and the level of integration of the CiTop with standard interventional angiography procedure: Balloon angioplasty, placement of stent.
