Abstract
A clot removal device for removing clot from a body vessel comprising an expandable structure and an elongate member. The elongate member can have a proximal end and a distal end, the elongate member being connected to the expandable structure at its distal end. The expandable structure can have a constrained delivery configuration, an expanded clot engaging deployed configuration, and an at least partially constrained clot pinching configuration. At least a portion of the expandable structure can be configured to engage clot in the expanded deployed configuration and to pinch clot on movement from the deployed configuration to the clot pinching configuration.
