A novel approach to chronic total occlusions: the crosser system.

Objectives: To evaluate safety and efficacy of the CROSSER CTO Recanalization System (CROSSER).

Background: The CROSSER, a novel device dedicated to recanalization of chronic total occlusions (CTO), relies on a monorail catheter delivering vibrational energy to facilitate the crossing of occluded coronary arteries.

Methods: We included de novo or restenotic occlusions in native coronary arteries with typically unfavorable characteristics and a prior failed guidewire attempt either performed in a previous procedure or just before the usage of the CROSSER.
