Method and Devices for Passing a Chronic Total Occlusion and Re-entry into a True Lumen

摘要

Methods and devices are disclosed for passing Chronic Total Occlusion (CTO) from subintimal location and re-entry into a true-lumen of the patient using transient fenestration approach. The transient fenestration is induced by balloon dilatation within the CTO, and a guidewire quickly trails into a true lumen.
