A device and a method for increasing or restoring a flow in a body lumen are provided. The device and the method may 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 device may comprise a pusher tube and an expandable compartment. The expandable compartment may comprise a control element, a reconfigurable element, and supportive element. The supportive element is configured to adjust a radial force and a configuration of the reconfigurable element, thereby allowing highly efficient removal of an occlusion from a blood vessel and/or reopen a blood vessel with least or no damage to the body lumen.
