Abstract: An axial flow pump (10) is presented which includes a housing (1) with an inlet (2) and outlet (3) and a magnetically active rotor (5) in the housing which is provided with a passage (6) in the interior and with at least one spiral-shaped vane (7) in the passage, wherein the pitch of the vane (7) varies in the axial direction. The axial flow pump (10) furthermore includes an electromagnetic drive (4, 8) with a stator (8) which is arranged at the housing and cooperates with a magnetically active rotor.

Abstract: The ultrasonic probe (1) is provided for a stereoscopic image forming system, which relates to a raster-like recording of data and its electronic processing. The probe includes groups (12) of sound transducers (11), which are arranged inside an elastomeric envelope (10) on a cylindrical carrier, rotatable around a longitudinal axis. The carrier is made up of at least two segments (3, 4). The segments are tiltable relative to one another through a tilting angle, and what is more about a tilting axis, which lies transversely to the longitudinal axis and preferably eccentrically to it. There is a stable positional state, in which the segments adopt a position with alignment in the direction of the longitudinal axis under the influence of a dynamic and/or static resetting force.

Abstract: The combination of a human medical vessel prosthesis (1) comprising a measuring probe (2) with a transponder, which measuring probe can be anchored to the vessel prosthesis, and allows the function of the vessel prosthesis to be monitored over longer periods of time. Suitable measurement parameters such as pressure values can be detected by the measuring probe (2) and be transmitted in a wireless manner with the aid of the transponder to a transceiver apparatus where they are available for evaluation.
