摘要： A method of removing material from a blood flow lumen generally includes providing a device having a cutting element and an opening, advancing the device through the blood flow lumen to a site where material is to be removed, forcing the opening toward a wall of the site where material is to be removed, and moving the cutting element and the opening so that material in the blood flow lumen is cut by the cutting element and directed into the opening for removal as the cutting element and opening are moved through the blood flow lumen. In some embodiments, the device may be deflected or bent to force the opening toward a wall to remove material. The cutting element may be rotatable and may have an axis that is movable, that is not parallel to the longitudinal axis of the device, or both. In some embodiments, the cutting element is movable between retracted and deployed positions for advancing the device to a site for treatment and for removing material, respectively.

摘要： A method of removing material from a blood flow lumen includes providing a device having a cutting element and an opening, the cutting element being movable relative to the opening. The method then includes advancing the device through a patient's vascular system to the blood flow lumen. Finally, the method involves moving the cutting element and the opening relative to the blood flow lumen so that a continuous piece of material is severed by the cutting element and directed into the opening as the cutting element and opening move through the blood flow lumen, the continuous piece of severed material being directed into the device for removal from the patient. The method may include providing a device having a rotatable cutter that, in some embodiments, is not parallel to the longitudinal axis of the device, is movable, has retracted and deployed positions, or any combination thereof.

摘要： A debulking catheter comprising a debulking assembly for debulking a body lumen. The catheters of the present invention can include a flexible proximal portion coupled to a rigid distal portion. A tissue debulking assembly can be disposed within the rigid portion to debulk the body lumen. In exemplary embodiments, the rigid portion is rotatably coupled to the flexible portion such that rotation or deflection of the rigid portion, relative to the flexible portion, can expose the tissue debulking assembly through a window in the catheter to debulk the body lumen.
