Abstract
A method for increasing or restoring a flow in a body lumen can treat conditions related to a stroke, such as an ischemic stroke, by removing an occlusion from a blood vessel and/or reopen a blood vessel. The method makes use of a device that includes a central wire, a pusher tube, a distal structure, and a proximal structure into the blood vessel, in which the distal structure is closed at its proximal end. A clot or occlusion present in the body lumen such as an artery may be engaged in and/or between the distal and proximal engaging elements. Further, the positions of one or both of the engaging elements and the distance between them can be adjusted to ensure the engagement of the clot or occlusion.
