摘要：
A clot removal device for removing clot from a body vessel includes an expandable structure having a constrained delivery configuration, an expanded clot engaging deployed configuration, and an at least partially constrained clot pinching configuration, the expandable structure including a proximal section comprising a plurality of struts with opening angles； a mid-section distal of the proximal section and comprising a plurality of struts with opening angles and cells larger than 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 a microcatheter.
