    Abstract: A device and method for establishing retrograde blood flow during recanalization of a vessel having a targeted blockage. While in a collapsed state an occluding component is introduced distally intravascularly traversing the targeted blockage to its distal side. Then, the occluding component transitions to an expanded state having an enlarged diameter forming a seal with an internal wall of the vessel prohibiting anterograde blood flow beyond the expanded occluding component. Retrograde blood flow is thereby established in a region of the vessel bound at one end by the occluding component and at an opposite end by the targeted blockage by dispensing a flushing fluid into the region of the vessel.

    Abstract: The invention relates to a method for machining a rack and to a rack (1) machined according to said method, for example a steering rack. In said method, the stress pattern that is present after hardening and/or straightening the rack and that has a chaotic internal stress distribution of tensile and compressive stresses is converted into a stress pattern that optimizes the strength and the use of the material and also the diameter of the rack, such that, without altering the structure, at least the region of the gear teeth (2) is pre-stressed, in a functionally combined series of steps of a machining pass, with a deliberately introduced internal compressive stress without tensile stress and with a predominantly uniform stress distribution or stress plane.

    Abstract: Verifying whether a magnetic field resistance mechanism is properly engaged in a drainage valve having an adjustable valve unit including a rotating construct and a pair of primary magnetic elements for programming the valve unit. Using a toolset, a determination is made whether the magnetic field resistance mechanism is properly engaged. An alert is generated whether the magnetic field resistance mechanism is at least one of properly engaged or not properly engaged based on: (i) a measured angular position of a detected one of the pair of primary magnetic elements relative to a direction of flow of fluid through the valve; and/or (ii) a measured distance separation between respective centers of the pair of primary magnetic elements.

    Abstract: Microwave measuring arrangement for determining loading two-phase flow with gaseous carrier medium in tube of channel system (1) with small solid and/or liquid particles. Microwaves with frequencies between 0.95 and 1.05 times the frequency of waveguide fundamental wave, are coupled into an electrically conductive section of the tube/channel system (1), section being delimited by filed rods (4,4′) and acting as resonator, the shift in the resonant frequency of the resonator on account of loading of the medium with solid and/or liquid particles is determined. To suppress interference (reflected, diffracted and/or superimposed) in the tube/or channel system (1), two auxiliary field rods (6, 7 and 6′, 7′) assigned to each filed rod (4,4′) are provided, Auxiliary filed rods (6, 7 and 6′, 7) are arranged at an angle α with respect to the field rod (4, 4′) of α=+45°±10 and/or α=−45°±10° and/or α=+135°±10° and/or α=−135°±.

    Abstract: An implantable valve assembly including a drainage catheter having a central lumen transitioning into a plurality of distinct branch lumen made of a shape memory material. A bioabsorbable dip coating secures the distal end of the plural distinct branch lumen together in physical contact with one another. Each branch lumen has an outer perimeter comprising at least one of a first outer surface section and a second outer surface section. In a secured state with the plural distinct branch lumen held together by the dip coating fluid is prohibited from passing through the holes defined in the first outer surface section. Bioabsorbable blocking members disposed about the outer perimeter of the assembled branch lumen mask holes defined in the second outer surface section prohibiting fluid from entering therein. In a time staggered fashion, the bioabsorbable elements absorb exposing new holes through which the fluid drains.

    Abstract: An elastomeric journal bearing, comprising inner part (2) extending in axial direction (x), outer sleeve (3) surrounding inner part (2), elastomeric bearing body (4) arranged between inner part (2), outer sleeve (3), connected to inner part (2), said bearing body comprising at least two radially extending webs (5, 6) which are offset in circumferential direction (u), and two annular walls (7, 8) which are offset in axial direction (x), between which extend axially webs (5, 6), and at least two chambers (10, 11) filled with liquid (9) and are separated from each other in circumferential direction (u) by webs (5, 6), said chambers being fluidically connected via at least one channel (12). The axial ends (36, 37, 38, 39) of the webs (5, 6) have at least in the region of the radially outer web ends (22, 23) axial end faces (40, 41, 42, 43) which bear against the walls (7, 8).

    Abstract: A seating furniture chassis including a drive mechanism, a drive shaft, a gear mechanism and a lifting mechanism. The drive mechanism sets the drive shaft in rotation, while the lifting mechanism raises and lowers a seat face. The drive shaft is connected to the lifting mechanism via the gear mechanism. Rotation of the drive shaft in a first direction triggers raising of the seat face, while rotation of the drive shaft in a second direction triggers lowering of the seat face.
