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

This study has been terminated.
(product development was cancelled)

Liat Shochat, Ovalum Identifier:
First received: June 3, 2007
Last updated: July 6, 2013
Last verified: July 2013

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.

Clinical Inclusion Criteria:

  • Patient with symptomatic peripheral vascular disease, intermittent claudication less than 30 meters, rest pain or tissue ischemia.(Fontain grade 3-4)
