Claim Text:
1. A clot removal system, comprising: first and second barriers, wherein each of the first and second barriers has an expanded configuration forming an occlusion within a vessel and a collapsed configuration; at least one deployment device for distally deploying the first barrier relative to a clot, proximally deploying the second barrier relative to the clot, and delivering a thrombolytic agent into an isolated segment defined by the first and second barriers in the expanded configurations; and an impeller including a cylindrical hub having at least two impeller blades attached to rotate with the cylindrical hub, wherein each of the at least two impeller blades has a proximal end attached to the cylindrical hub and a distal end attached to the cylindrical hub, wherein the impeller has a transport configuration in which the deployment device contacts and urges the at least two impeller blades toward being at least partially retracted within the cylindrical hub against a bias toward a deployed configuration in which the at least two impeller blades are out of contact with the deployment device and moved away from the cylindrical hub by action of the bias, wherein the at least one deployment device is used for positioning the impeller within the isolated segment.
