1. A method of manufacturing an implantable braid comprising a plurality of groups of first filaments, second filaments, and third filaments, each of the first filaments being formed out of a radiopaque material, each of the second filaments being a monofilament formed out of a support material having a tensile strength greater than a tensile strength of the radiopaque material, and each of the third filaments being a drawn filled tube (DFT) wire comprising a core formed out of one of a radiopaque material and a support material, and a sheath around the core formed of the other of the radiopaque material and the support material, wherein the support material of the DFT wire has a tensile strength greater than a tensile strength of the radiopaque material of the DFT wire, the method comprising:
arranging the groups of first filaments, second filaments, and third filaments in a starting filament arrangement on a braiding machine in which at least one group of first filaments is not directly adjacent to any one of the groups of third filaments; and
braiding the starting arrangement of first filaments, second filaments, and third filaments together to form the implantable braid.
