Abstract
A method of removing clot from a vessel, including delivering a clot retrieval device across the clot, wherein the clot retrieval device includes an inner body having a collapsed delivery configuration and an expanded deployed configuration; and an outer body extending along a longitudinal axis and at least partially overlying the inner body. The outer body includes a first scaffolding section, a second scaffolding section hingedly connected distal of the first scaffolding section; the first and second scaffolding sections of the outer body being expandable to a radial extent which is greater than the radial extent of the inner body in the deployed configuration to define a clot reception space between the inner and outer bodies. The method also includes expanding the clot retrieval device; and urging, by the expanding of the first and second scaffolding sections, at least a portion of the clot therebetween.
