Abstract
Methods and apparatus for retrieving a blood clot are disclosed. The apparatus comprises an expandable wire frame for deployment using a push wire within a microcatheter. When deployed in the vicinity of a blood clot, the wire frame is configured to expand and trap the blood clot allowing the blood clot to be removed. The expandable wire frame is connected to the push wire at distal and proximal ends. One or more expansion stops define a minimum distance between the distal and proximal ends of the expandable wire frame and a point of maximum extension of the expandable wire frame. This may help the user to control the configuration of the apparatus as it is being used within the vascular system.
