Abstract: A system for testing MEMS-structures includes a microforce sensor, two or more multi-axis micropositioning units, at least one electrical probe and a sample holder on which a MEMS-structure is mounted. At least one of the multi-axis micropositioning units is motorized and at least one additional micropositioning unit is equipped with at least one electrical probe to apply electrical signals or to measure electrical signals at one or multiple locations on the MEMS structure. The system with the aforementioned components allows a combined electrical and probe-based mechanical testing of MEMS-structures.

Abstract: The invention concerns a stent 1 for the bracing and/or holding-open of a body cavity having a tube 2 made from an elastic material, a tubular weave 3 comprising filaments 5 seating in close adjacency to the outer surface of the tube 2 as well as a coating 4 applied to the outer surface of the tube 2 which attaches the weave 3 to the outer surface of the tube 2. The coating 4 is adapted to have a structured outer surface dominated by the weave 3. The stent 1 in accordance with the invention can be produced economically with adjustable restoring forces and facilitates a secure placing within the body cavity. Means for preventing drifting within the body cavity can also be introduced onto outer surface of the stent.
