METHODS AND APPARATUS FOR FLOW RESTORATION A removable, integrated apparatus-thrombus mass, comprising a thrombus (12) at least partially engaged with an apparatus, wherein the apparatus comprises: a structure (5) comprising a first plurality of cells, the structure having a proximal end (3) and a distal end (2), the proximal end and the distal end being open, and the first plurality of cells being configured to engage at least a portion of the thrombus (12); a tapering portion comprising a second plurality of cells, the tapering portion disposed toward the proximal end (3) of the structure (5); and a connection portion, at which the tapering portion converges, located at a proximal end of the tapering portion; wherein the apparatus is self-expandable and pre-formed to assume a volume-enlarged form and, in the volume-enlarged form, takes the form of a longitudinally open tube tapering toward the connection portion. |
