Abstract: A charging infrastructure unit for at least partly electrically driven vehicles has one or more DC supply devices for charging one or more vehicles, one or more supply connections, and one or more charging connections. At least one of the one or more DC supply devices can be supplied with energy via one or more supply connections, and a respective vehicle can be connected to a charging connection. There is also described a charging infrastructure with such charging units.

Abstract: The invention relates to a rail module (1) having rail portions (2) and having a linear drive for moving a rail-bound carriage. The linear drive has at least one drive module (4) which can be brought into operative connection with at least one reaction element. Here, the reaction element is secured, independently of the drive module (4), to the carriage in a drive region and the drive module (4) is arranged fixedly in relation to the rail module (1). When the rail module (1) is used as intended, the rail-bound carriage can be moved along at least a first or a second movement axis. The invention also relates to a rail transport system made up of at least two of the rail modules.

Abstract: A catheter for the opening of occlusions in blood vessels and for similar purposes has a distal end with a one-piece or composite sleeve which can be inserted into an occlusion and thereupon expanded by a balloon or a spring. The sleeve is sufficiently stiff to resist localized deformation by hard regions of an occlusion, and such sleeve is withdrawn from the blood vessel when the opening step is completed. The sleeve can constitute a scroll, a longitudinally slotted hose or a combination of a scroll or hose with an elastic jacket which tends to reduce the diameter of the scroll or hose.

Abstract: A guide which can be introduced into a narrow passage in a human or other animal body, such as into a narrow blood vessel in a human heart, has a flexible tube which is made of a plurality of helically wound and closely adjacent wires of a metallic or plastic material. An intermediate portion of the tube adjacent its distal end is permanently curved or is ductile so that its curvature can be changed in order to enable a person in charge to select the orientation of the distal end of the tube for convenient advancement from a wider passage into a narrower passage which is inclined with reference to the wider passage. The inserted tube serves as a guide for introduction of a dilatation catheter, another catheter, a cardiac pacemaker electrode or any other slender elongated flexible medical device which is to be temporarily or permanently introduced into the heart or into another organ or another part of an animal body.

Abstract: A rotatable dilatation catheter comprising a pressure member formed by a coil of wire having open turns adjacent a distal end of the coil with the open turns being expandable to form a pressure member capable of obtaining various diameters. The enlargement of the diameter of the pressure member can occur by means of forming the member of an elastic material which will tend to expand, by means of applying a compressive axial force to the open turns to cause their radially expansion and/or applying a centrifugal force to the turns.
