Vascular catheters designed for use in crossing through chronic total occlusions (CTO) in the peripheral arteries using high-frequency mechanical vibrations. These devices are catheters with appropriate dimensions (i.e., diameter and length) for use in the peripheral arteries; they typically include a core wire that transmits the mechanical vibrations to the tip of the catheter and also have irrigation capabilities. Peripheral artery occlusion crossing vascular catheters are mainly intended to facilitate guidewire passage across the CTO, permitting subsequent angioplasty procedures and/or stent placement.
