Claim 0:
1. A device for removing a clot from a blood vessel having a constrained delivery configuration and an expanded deployed configuration, the device comprising:
a first shaft, a second shaft, and a framework of struts forming an expandable member extending distally from the first and second shafts, the expandable member comprising:
an inner tubular lumen and a longitudinal axis extending therethrough;
an inner body connected to the second shaft comprising a plurality of cells expandable in the deployed configuration around the longitudinal axis; and
an outer body connected to the first shaft comprising a plurality of cells expandable in the deployed configuration to a greater extent than the inner body, the outer body disposed around the inner body;

wherein the first shaft is coincident with the second shaft and the longitudinal axis;
wherein the inner body and outer body are independently translatable and rotatable with respect to each other about the longitudinal axis between the deployed configuration and a clot pinching configuration;
wherein the cells of the inner body and the cells of the outer body are configured to pinch a clot located in the cells when in the clot pinching configuration;
wherein the plurality of cells of the inner body are aligned with the plurality of cells of the outer body in the expanded deployed configuration;
wherein the plurality of cells of the inner body are not aligned with the plurality of cells of the outer body in the clot pinching configuration and; wherein the clot pinching configuration is achieved by distally translating the inner body relative to the outer body until at least a portion of the clot is compressed between the plurality of cells of the inner body and the plurality of cells of the outer body.
