1. An implantable vaso-occlusive device for occluding an aneurysm, comprising:
a braided member formed out of a plurality of interwoven braid filaments, the braided member having a compressed configuration when constrained in a lumen of a delivery catheter, and an expanded configuration when not constrained, in which the plurality of interwoven braid filaments are disposed circumferentially about an elongate axis of the braided member,
wherein in the expanded configuration, the braided member defines a plurality of enlarged cross-section segments spaced apart along the elongate axis thereof, wherein adjacent enlarged cross-section segments of the plurality of enlarged cross-section segments are connected by respective reduced cross-section segments,
wherein the plurality of interwoven braid filaments are interwoven according to a first weave pattern to create the plurality of enlarged cross-section segments, and wherein the plurality of interwoven braid filaments are interwoven according to a second weave pattern different than the first weave pattern to create the respective reduced cross-section segments,
wherein in the expanded configuration, the plurality of enlarged cross-section segments comprise the plurality of interwoven braid filaments formed into a flat, ribbon-like configuration, and the respective reduced cross-section segments comprise the plurality of the interwoven braid filaments formed into a round, tube-like configuration having a circular cross-section.
