Abstract: The present invention relates a vascular prosthesis for a blood vessel of a patient, which has the following: a hollow-cylindrical main body with a main lumen extending therein, an also a multiplicity of stent rings, which are not connected to one another, are arranged spaced apart one behind the other in the longitudinal direction of the vascular prosthesis and running around in a meandering formation. The vascular prosthesis also has four side branches, which extend distally into the main lumen from fenestrations in the prosthesis material lying between the stent rings.

Abstract: The invention relates to a self-expanding vascular implant for implanting into a blood vessel, the implant comprising a hollow cylindrical body with a proximal and a distal end and with a longitudinal axis; comprising stent springs, which are successively arranged and spaced from one another over the longitudinal axis of the body, each stent spring meandering; and comprising an implant material, which is fixed to the stent springs and connects same. The stent springs have pointed arches which alternately point toward the proximal and distal direction and comprise alternating crests and troughs that are connected to one another via legs of different lengths, whereby a stent spring has pointed arches, which are circumferentially and successively arranged and which have different heights, said pointed arches consisting of higher and shorter pointed arches.

Abstract: A device for transmitting a torque from a drive device (200) onto a roller in a roll stand. In order to make the device independent from the continuous external supply of lubricant, the lubricant spaces in the two pivot bearings are connected to one another in a fluidically conductive manner by way of a feed channel and a return channel for the lubricant in the region of the spindle such that a closed circuit for the lubricant is formed, and that the least one pump device is integrated in the circuit in order to maintain the circulation of the lubricant in the circuit.

Abstract: The present invention relates to a self-expanding vascular implant for implanting into a blood vessel of a patient. The vascular implant has a main body and at least one side body, and has integrally formed, one-piece stent springs, which are successively arranged in the longitudinal axis of the main body, with each stent spring meandering perpendicular to the longitudinal axis, and an implant material which is fixed to and connects the stent springs. The stent springs have pointed arches that alternately point toward the proximal end and the distal end of the main body and parallel to the longitudinal axis thereof. The at least one side body that branches off from the main body is, in the self-expanded state, set out at an angle relative to the longitudinal axis of the main body.
