  • Systems and methods for restoring blood flow to a vessel
    Patent number: 10194928
    Abstract: In one illustrative embodiment, a thrombectomy device is disclosed. The thrombectomy device includes a treatment portion, comprising a reversibly-expandable framework configured to be deployed from within a microcatheter into a selected vasculature for removing thrombus or embolus. The thrombectomy device further includes a substantially tubular connection member disposed on a proximal end portion of the treatment portion configured to receive a terminal portion of a delivery member for positioning the treatment portion within the vasculature. The framework comprises structural features for engaging the thrombus or embolus including one or more of: framework peaks and valleys along a long axis of the treatment portion or a plurality of strut members.
