A method for manufacture of braided multifilament structures for an endoprosthesis for ramification of an anatomical conduit. The method includes the operation of braiding filaments, made of a matter chosen from among the biocompatible elastic, superelastic and shape-memory materials, around a first mandrel, along the length of the first mandrel whose diameter corresponds to a branch of a base element. The method further includes setting up at least one auxiliary mandrel parallel to the first mandrel. The auxiliary mandrel includes a first end and a second end, of cross-section corresponding to those of a lumen. The first end is inserted in a straight line with the braid in progress, upstream of the braiding point, and the assembly has a cross-section corresponding to that of a trunk of a base element. The method further includes continuing the braiding around the assembly along a length corresponding to at least that of the trunk of a base element.
