A medical device (100), configured to perform an endovascular therapy, e.g., thrombectomy, can comprise an elongate manipulation member (104) and an intervention member (102). The intervention member (102) can comprise a proximal end portion (110) and a mesh. The proximal end portion (110) can be coupled with the distal end portion of the elongate manipulation member. The mesh can have a plurality of cells (116) and, be compressible to a collapsed configuration for delivery to an endovascular treatment site through a catheter (107), and be self-expandable from the collapsed configuration to an expanded configuration. At least a portion of the mesh, from a first location to a second location along the mesh, can be configured such that an amount of cell deformation in response to longitudinally directed tensile forces decreases by less than 5% or increases in a distal direction along the portion of the mesh.
