US Patent 8048139 Reversible applicator for an intraluminal endoprosthesis

A reversible applicator for an intraluminal endoprosthesis with a pusher, an outer sheath sliding longitudinally relative to this pusher, and an endoprosthesis arranged at it's distal part. A retention element formed by an expandable braid that widens in a bulb shape in the expanded state, integrally joined to the pusher, is arranged longitudinally inside the endoprosthesis that is to be fitted in place. This bulb compresses the proximal part of the endoprosthesis against an inner wall of the sheath in such a way as to allow the endoprosthesis to be retracted inside the sheath.
