Abstract: Provided is a turning device for turning pipes with a large diameter about their longitudinal axis. The turning device includes a base body and two supporting devices that are arranged on the base body. Each supporting device includes a pedestal and at least one rocker element that is pivotably mounted in a receptacle of the pedestal. The pedestal is connected to the base body. The rocker elements each include one or more rollers. The turning device adapts to different pipe diameters as a result of the rocker elements, so that no exchanging of the turning device is necessary and multiple turning devices do not need to be kept on hand for different pipe diameters.

Abstract: A vascular implant, in particular a prosthetic heart valve, for providing valve function, has a stent structure with a proximal conical-convex inflow region, a distal, linear cylindrical outflow region, an intermediate transition region, and a corresponding valve arrangement. When the stent structure is in the expanded state, a higher maximum radial force exists in the inlet region in direct comparison to the lower maximum radial force in the outlet region and in the transition region.
