摘要：
A guidewire having a spreader or at least one centering device which may be used to open occluded vessels or other biological passages, especially chronic total occlusions. The guidewire may be used to either open the lumen or to center a boring device within the lumen, so that the chronic total occlusion can be crossed, and an interventional procedure can then be performed.
