Claim Text:
1. A device positionable within a small intracranial blood vessel exhibiting an occlusion caused by a thrombosis or an embolism, the device comprising a self expandable tubular body, said tubular body configured to be constrained in a first small diameter state for manipulation to, and through, the occlusion of the small blood vessel, and a second large diameter state for when said tubular body is deployed within the occlusion, a delivery catheter for delivery of said tubular body; said device comprising a first member coupled to a proximal end of said tubular body, and a second member coupled to a distal end of said tubular body, said members pullable and pushable relative to each other to change a cross sectional area of said tubular body after self-expansion thereof; wherein at least a portion of said first member is an integral part of said self expandable tubular body, formed as a local elongated protrusion of said self expandable tubular body; wherein said first member is extendable through the delivery catheter, running through the catheter and out of a proximal end thereof; wherein said second member comprises a filament that extends distally beyond said distal end of said tubular body; and wherein said first and second members are movable with respect to each other to compress said tubular body to increase its diameter or stretch said tubular body to decrease its diameter.
