An implant includes an optimised structure for implantation in a canal or in a cavity of a living being. The structure includes a tubular structure extending along a longitudinal axis, said structure having at least one braided longitudinal sector of metal wires and open longitudinal ends. The tubular structure has a braided longitudinal sector at each longitudinal end and at least one twisted longitudinal sector, produced with said metal wires in order to form, with continuity, said tubular structure.
