Vascular plaque removal systems, devices, and methods

Abstract

Systems, devices, and methods for removing plaque from a patient's vasculature are disclosed. 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, a receiving space, and a severing element, such as, for example a thrombus-breaking element. The dissection tip can radially adjust to circumferentially maneuver between a core of plaque or a blood clot and a patient's vasculature. The receiving space can receive the plaque or clot that passes within the dissection tip. The severing element can at least partially sever or break apart the plaque or clot.
