Methods and apparatus for flow restoration

An apparatus for removal of a thrombus in a cerebral blood vessel, comprising:

• a self-expandable tubular structure of interconnected struts comprising a plurality of mesh cells having a proximal end and a distal end, the proximal end and the distal end being open, wherein the self-expandable tubular structure is configured to expand from a compressed form to an expanded form at a site of the thrombus;
• a tapering portion operatively connected to the proximal end of the self-expandable tubular structure;
• a connection portion operatively connected to a proximal end of the tapering portion wherein the tapering portion is configured to converge at the connection portion;
• and
• a push or guide wire, wherein a distal end of the push or guide wire is configured to be permanently attached to the connection portion,
• wherein the self-expandable tubular mesh structure can take a volume-reduced form, and the self-expandable tubular mesh structure forms edges and is curled up such that the edges overlap in the volume-reduced form,
• wherein the self-expandable tubular structure is configured to apply an outward radial force on the thrombus during and after the self-expandable tubular structure expands, and
• wherein the self-expandable tubular structure is configured to interlock with at least a portion of the thrombus, the portion of the thrombus extending both inside of the self-expandable tubular structure and outside of the self-expandable tubular structure.
