Abstract
A deflectable and torqueable hollow guidewire device is disclosed for removing occlusive material and passing through occlusions, stenosis, thrombus, plaque, calcified material, and other materials in a body lumen, such as a coronary artery. The hollow guidewire generally comprises an elongate, tubular guidewire body that has an axial lumen. A mechanically moving core element is positioned at or near a distal end of the tubular guidewire body and extends through the axial lumen. Actuation of the core element (e.g., oscillation, reciprocation, and/or rotation) creates a passage through the occlusive or stenotic material in the body lumen.
