Abstract
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 tubing compartment, a central wire, and an engaging compartment. The engaging compartment may comprise a distal engaging element and a proximal engaging element. 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 therebetween can be adjusted to ensure the engagement of the clot or occlusion.
