Claim 15:
16. A system for removing a clot from a vessel, comprising:
a microcatheter; and
a clot removal device removably inserted in a lumen of the microcatheter, comprising:
an expandable structure having a constrained delivery configuration within the lumen, an expanded clot engaging deployed configuration when distal of the microcatheter, and an at least partially constrained clot pinching configuration, the expandable structure comprising:
a proximal section comprising:
a plurality of struts with opening angles and cells; and
alternating clot embedding cells and segments of lower outward radial force; and

a mid-section distal of the proximal section and comprising a plurality of struts with opening angles and cells larger than the cells of the proximal section, the mid-section being configured to expand a larger radial extent in the deployed configuration than the proximal section to provide clot grip and retention during retraction of the clot;
wherein the proximal section is configured to pinch the clot from the body vessel when partially resheathed by the microcatheter.
