摘要:
Systems and methods for crossing stenosis, partial occlusions, or complete occlusions within a body lumen. The systems generally include an elongate member such as a hollow guidewire that houses a rotatable and translatable drive shaft. The drive shaft typically has a distal portion that is advanced to create a path in the occlusive material that is large enough to allow the hollow guidewire to cross the occlusive material.
