1. A system comprising a plurality of expandable tip assemblies configured to address an occlusive thrombus within a blood vessel for providing progressive therapy without distal embolic protection, the system comprising:

  • a first expandable tip assembly comprising a first elongate member and a first self-expanding scaffold;

    wherein the first self-expanding scaffold is coupled to a distal end of the first elongate member;

    wherein the first self-expanding scaffold comprises an open distal end without a distal embolic protection member or device;

    wherein the first self-expanding scaffold comprises open cells formed by a pattern of struts and bridges, wherein said cells have a cell size configured to hinder penetration of thrombus material within the first self-expanding scaffold, thereby increasing an amount of blood flow through the first self-expanding scaffold; and

    a second expandable tip assembly comprising a second elongate member and a second self-expanding scaffold;

    wherein the second self-expanding scaffold is coupled to a distal end of the second elongate member;

    wherein the second self-expanding scaffold comprises an open distal end without a distal embolic protection member or device;

    wherein the second self-expanding scaffold comprises open cells formed by a pattern of struts and bridges, wherein said cells have a cell size larger than the cell size of the first self-expanding scaffold, wherein said cell size of the second self-expanding scaffold is configured to enhance penetration of thrombus material within the scaffold to facilitate capture of the thrombus;

    wherein, in use, the first self-expanding scaffold and the second self-expanding scaffold are adapted to radially self-expand from a non-expanded configuration to an expanded configuration and to transition from the expanded configuration to the non-expanded configuration upon unsheathing and re-sheathing of the first and second self-expanding scaffolds.
