Blood flow restorative and embolus removal methods

A method for restoring blood flow in an occluded cerebral blood vessel of a patient, comprising:

• accessing a cerebral artery having an occluded zone with a catheter system, the catheter system comprising a microcatheter and a blood flow restoration device,
• wherein the blood flow restoration device comprises a distal self-expandable capture device and a proximal delivery member,
• wherein the distal self-expandable capture device is eccentrically coupled to the proximal delivery member by a plurality of tether lines,
• wherein the distal self-expandable capture device is configured to be delivered through the microcatheter in a compressed configuration and deployed to an expanded configuration upon retraction of the microcatheter;
• locating the occluded zone within the artery caused by an occlusive object;
• advancing the catheter system to the location of the occluded zone;
• deploying the distal self-expandable capture device to the expanded configuration at the location of the occluded zone by retracting the microcatheter such that the capture device engages and captures the occlusive object upon deployment of the capture device,
• wherein the occlusive object is at least partially engaged and captured on an external surface of the capture device;
• and
• removing the occlusive object by withdrawing the blood flow restoration device.
