    摘要: The present invention relates to methods and devices for predicting restenosis, and for treating atherosclerosis to prevent or reduce the incidence of restenosis. Methods of predicting restenosis in a stenosed peripheral artery may include quantitative histology of the vessel. For example, a method of treating a stenosed artery (and particularly a peripheral artery) may include the steps of determining a level of hypercellularity and one or more of the lipid-richness and extent of inflammatory cell inclusion in the tissue. An index of restenosis based on the hypercellularity and lipid richness and/or extent of inflammatory cell inclusion in the tissue may be determined. Systems for treating or preventing restenosis may include one or more imaging modalities for imaging tissue regions and determining the level of hypercellularity and one or more of the degree of lipid-richness and the extent of inflammatory cell inclusion in the tissue region.

    摘要: A debulking catheter comprising a tissue debulking assembly for removing a continuous strand of material from a body lumen. Catheters of the present invention generally include a catheter body having proximal and distal portions and a tissue debulking assembly disposed at least partially within the distal portion. The tissue debulking assembly is radially movable to expose at least a portion of the assembly through a window on the catheter body. The catheter is advanced transluminally through the body lumen to contact material in the body lumen and remove a plane of continuous material that has a length that is typically longer than a length of the window on the catheter. The continuous material may be directed into a collection chamber. Thereafter, the material may be removed from the collection chamber and preserved or tested.

    摘要: Lumenectomy material is tested to determine the efficacy of a test drug in a patient population having a cardiovascular condition. The material is removed from at least a first and a second patient and tested for one or more markers of a cardiovascular condition. The first patient is administered the test drug, and the second patient is administered a placebo. At a later date, more lumenectomy material is removed and tested for the same marker or markers. The presence, absence or amount of the markers is compared in the first patient receiving the drug and the second patient receiving the placebo to determine whether the drug is effective in the patient population. The drugs tested include drugs believed to be effective in treating a cardiovascular condition. The markers used can include any marker that can indicate the effectiveness of the drug being tested.

    摘要: Lumenectomy material is tested to determine the presence or likelihood of a condition of a patient. The lumenectomy material is in the form of at least one continuous tissue strand collected in vivo from an inner surface of a body lumen of the patient. The presence of at least one marker of a disease is determined. The disease may be hypertension, hyperlipidemia, depression, obesity, metabolic syndrome, insulin resistance, kidney damage, or diabetes. The patient is identified as having or as likely to develop the disease if a marker of the disease is identified in the lumenectomy material of the patient.

    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: 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.

    摘要: Atherectomy device for removing material from an atheroma in the vascular system. A cutter is mounted in a cylindrical housing having a cutout on one side thereof at the distal end of a catheter. The catheter has a single luminal opening, and a flexible drive cable for operating the cutter passes through this opening. An inflatable balloon is positioned outside the housing opposite the cutout, and a medium for inflating the balloon is introduced through the luminal opening of the catheter.
