Disclosed is an application aid (1) for introducing a material (12) used for the treatment of bone defects into a natural bone or a natural bone structure. Said application aid (1) comprises a largely flexible, tubular or sleeve-shaped outer part (2) that is composed of at least two components (3, 4) which can be coaxially moved into each other, a largely flexible, preferably tubular or sleeve-shaped inner part (7), and a discharge port (11) for the material, preferably on the outer part (2). The inventive application aid is preferably embodied such that at least one element which can be moved radially outward at least in part is provided in the interior. Said element represents particularly a balloon. |
