    摘要: The invention relates to a method for producing a vascular implant. The method comprises: obtaining vessel parameters; creating a computer-aided model of a vascular implant based on the obtained vessel parameters, wherein the vascular implant comprises one or more modules, each comprising at least one tubular liner body; selecting one or more structural elements of a respective module from the group consisting of: one or more diameter changes along at least one tubular liner body, one or more bifurcations, one or more branches, one or more recesses, one or more local reinforcements, and one or more iliac vessel grafts. The method further comprises: determining parameters relating to the one or more selected structural elements; integrating the structural elements into the computer-aided model according to the determined parameters; and producing the vascular implant based on the created computer-aided model. Furthermore, the invention relates to vascular implants produced by means of the method.

    摘要: Devices and method are disclosed for a load allocation and monitoring for a resource to be allocated in a network, where the resource to be allocated is a critical resource in terms of supply security for a population group and/or a system, and the critical resource comprises electric power, where the network is subdivided into network units, and each network unit has a network unit controller. In some examples, the method includes storing network unit control methods, network unit parameter data sets, and subnetwork monitoring methods in at least one blockchain; allocating a subnetwork monitoring unit to one part of the network; and transmitting a network unit control method and a network unit parameter data set to each network unit controller of the part of the network, and the transmitting of the network unit control methods and the network unit parameter data sets is cryptographically secured against reading and tampering with the network unit control methods and the network unit parameter data sets in such a manner that the corresponding reading and tampering are precluded to the greatest extent possible and occurs in such a manner that the proper functioning of each network unit controller of the part of the network is ensured; and monitoring the proper function of each network unit controller of the part of the network by means of the subnetwork monitoring unit using a corresponding subnetwork monitoring method.

    摘要: The invention relates to a degassing devive (25) for degassing blood, comprising a blood chamber (1, 1a, 1b) with a blood inlet (2) and a blood outlet (3), via which blood can be guided/is guided through the blood chamber (1, 1a, 1b), at least one underpressure chamber (11) with an underpressure attachment (8) via which the at least one underpressure chamber (11) is provided with an underpressure, at least one semipermeable membrane (4, 4a), which is arranged between the at least one underpressure chamber (11) and the blood chamber (1), wherein the blood chamber (1) comprises a first and a second sub-chamber (1a, 1b) which are arranged next to each other in a direction perpendicular to the direction of gravity, and a bridging region (9) which connects the two subchambers (1a, 1b) at their upper ends, wherein the blood inlet (2) is arranged in the lower region of the first subchamber (1a), and the blood outlet (3) is arranged in the lower region of the second subchamber (1b). The invention also relates to a system for extracorporeal treatment of blood.
