An implantable device for treating a vascular cavity or vascular malformation may include a plurality of wires woven to form a textile structure expandable from a compressed state to an expanded state. The textile structure may have a longitudinal axis and may include, in the expanded state, a first longitudinal segment, a second longitudinal segment, and a lumen configured to allow perfusion of blood through the textile structure parallel to the longitudinal axis. The first longitudinal segment may include a first circumferential portion including a first braid angle and a second circumferential portion opposite the first circumferential portion and including a second braid angle greater than the first braid angle. At least one of the first longitudinal segment and the second longitudinal segment may comprise a bulb.
