An endoprosthesis has an expanded state and a contracted state, the endoprosthesis includes a stent having an inner surface defining a lumen, having an outer surface, and defining a plurality of apertures through the outer surface, wherein the apertures are arranged in a micropattern; and a coating (e.g., polymeric coating) attached to the outer surface of the stent. The coating includes a base and a tissue engagement portion including a second surface facing outwardly from the stent, the tissue engagement portion including a structure that defines a plurality of holes extending inwardly from the second surface toward the base. The holes are arranged in a micropattern. When the endoprosthesis is expanded to the expanded state in a lumen defined by a vessel wall, the structure applies a force that may reduce stent migration by creating an interlock between the vessel wall and the endoprosthesis.

An improved composite structure and method for making same has been provided. The provided improved composite structure has locally strengthened areas within a reinforcement region. The locally strengthened areas within the reinforcement region have load distribution devices to redistribute load in order to (i) locally strengthen an area around damage induced by an initial momentary and direct transmitted load, and (ii) limit growth and propagation of damage induced by an initial momentary and direct transmitted load during a subsequent unbalance load. The improved composite structure reduces the impact of the fan blade out phenomenon in a weight efficient manner.

The invention relates to a method for manufacturing a heatable media line (100), in particular for conducting and simultaneously reheating brewing water or a freshly brewed hot beverage (1) in a hot-beverage dispensing machine (1000). According to the invention, along a hose line (2), at least one heat transfer foil which homogenizes the heat transfer via the hose line surface and which is composed of a material with a thermal conductivity at 0 C. of >10 W/mK, preferably >50 W/mK, is wound onto the outside, and an electrical heating medium is applied to the heat transfer foil, which electrical heating medium serves for heating the hose line surface.
