Abstract: 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.

Abstract: An elastic ring, defining an inner opening, an outer contour and an annular bearing surface between the inner opening and the outer contour. The ring is deformable between a rest position and an insertion position in which the inner opening has a diameter greater than its diameter in the rest position. The ring is also elastically biased towards the rest position. The ring includes at least three strands passing through the ring, each strand having a first end and a second end positioned on the outer contour, the inner contour of the opening being defined by a portion of each strand and having a pseudo-polygonal shape.
