    摘要： A rotating cutting head catheter for passage through chronic total occlusions or other refractory atherosclerotic plaque from diseased arteries is disclosed. The catheter's rotating cutting head is designed to reside safely within an outer protective sheath when not in use. The outer protective sheath contains one or more helical grooves or slots, and the cutting head contains protruding blades or projections that fit into these helical grooves or slots. Application of torque to an inner catheter or wire attached to the cutting head applies spin to the cutting head, and the force of the sheath's helical grooves or slots against the cutting head's protruding blades or projections advances the cutting head outward from the protective sheath. Once extended, the cutting head may now rotate freely. The device may use a guidewire to direct the cutting head to the desired position.

    摘要： Described herein are guidewire positioning and support devices, method for using them, method of treating a subject using them, and systems including such guidewire positioning and support devices. These devices typically include a rotatable distal tip region that may include one or more wedges. The wedges may be extendable from the rotatable distal tip. The distal end of the device may be steerable, and may be steered while still rotating the distal end of the device. The wedges (which may include sharp forward-cutting blades and blunt lateral portions) can be extended from the distal housing and locked in any position (extended, partially extended or retracted) and rotated clockwise and/or counterclockwise while locked in a retracted, extended or partially extended position. The distal region of the device may also be controllable steered from the proximal end of the device. Systems including these guidewire support catheters are also described, as are method of using them, including methods of treating chronic total occlusions.
