Claim 7:
8. A device for treating an occlusion in a body vessel, the device comprising:
a tubular inner lumen configured about a longitudinal axis;
an inner body comprising a constrained delivery configuration, an expanded deployed configuration, and a plurality of struts forming an inner clot scaffolding section comprising rings of cells;
an outer body disposed around the inner body comprising a constrained delivery configuration, an expanded deployed configuration, and a plurality of struts forming an outer clot scaffolding section comprising rings of cells; and
an elongate shaft assembly extending proximal to the inner and outer bodies, the elongate shaft assembly comprising a first tubular shaft connected to the outer body and a second shaft connected to the inner body,
wherein the first tubular shaft surrounds and 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 at least a portion of a clot is compressed between the struts of the inner body and the struts of the outer body when the inner body is in the clot pinching configuration;
wherein in the expanded deployed configuration, the cells of the inner body are aligned with the cells of the outer body;
wherein the cells of the inner body are not aligned with the 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.
