The invention relates to a medical device for inserting into a hollow organ of the body. The device has a compressible and expandable lattice structure made of webs, which are integrally connected to each other by web connectors and which bound closed cells of the lattice structure, wherein the web connectors each have a connector axis extending between two cells which, in a longitudinal direction of the lattice structure, are adjacent to each other. During the transition of the lattice structure from the production state to a compressed state, the web connectors rotate in such a way that an angle between the connector axis and a longitudinal axis of the lattice structure changes, in particular increases, during the transition of the lattice structure from a completely expanded production state to a partially expanded intermediate state.

Medical device for inserting into a hollow organ of the body

A medical device with a radially compressible and expandable lattice structure () contains at least one closed cell () delimited in each case by four webs () coupled to one another in one piece, of which at least one web () is embodied as a stabilisation web () with a first web width band at least two further webs () are embodied as connecting webs () with a second web width b, wherein the connecting webs () are arranged inside the cell () so that they lie parallel opposite one another and are connected to one another by the stabilisation webs () and wherein the ratio b/bbetween the first web width band the second web width bis at least 1.2.
