1. A medical device for removing concretions from hollow organs of the body, with a functional element, which has a rotationally symmetrical lattice structure and a means for holding a concretion in the lattice structure, and a catheter for introducing the functional element into the body and for removing it therefrom, the functional element being convertible from a compressed state in the catheter into an expanded state outside the catheter, in which the functional element is arranged distally from the catheter,whereinthe lattice structure has a cutting region with webs, which, during use, at least partially radially penetrate the concretion during the conversion of the functional element from the compressed state into the expanded state, and the holding means comprises at least one holding element, which is surrounded proximally and distally in the longitudinal direction as well as in the circumferential direction of the lattice structure by lattice cells and/or meshes of the cutting region, the lattice cells and/or meshes of the cutting region being arranged in the same cylindrical lateral surface of the lattice structure.
