VASCULAR PLAQUE REMOVAL SYSTEMS, DEVICES, AND METHODS

摘要

Systems, devices, and methods for removing plaque from a patient's vasculature. In one example, a medical article includes a catheter body and a dissection tip. The dissection tip can move between at least a first position and a second position and can be biased to expand radially from a longitudinal axis of the medical article when the dissection tip is moved from the first position to the second position. In one example, a dissection member includes a dissection tip and a receiving space. The dissection tip can radially adjust to circumferentially maneuver between a core of plaque and a patient's vasculature. The receiving space can receive at least a portion of a core of plaque that passes through the dissection tip.

1. A method comprising:
introducing a medical article into a patient's vasculature, the medical article comprising a radially adjustable dissection tip, a receiving space disposed proximal to the dissection tip, and an aspiration lumen disposed proximal to the receiving space; positioning the dissection tip between a volume of plaque tissue or a blood clot and an outer wall of the patient's vasculature; and receiving the volume of plaque tissue or blood clot in the receiving space.
