Systems, devices, and methods for removing plaque from a patients 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 patients vasculature. The receiving space can receive at least a portion of a core of plaque that passes through the dissection tip.
