  • Patent number: 11235138
    Abstract: A non-occluding intravascular pump comprises a shroud providing an inlet for incoming blood flow and an outlet for outgoing blood flow, wherein the shroud is a cylindrical housing; an impeller positioned within shroud, wherein a central axis of the shroud and impeller are shared; a motor coupled to the impeller, wherein the motor rotates the impeller to causes blood to be drawn through the inlet and output to the outlet, and the motor is centrally disposed and shares the central axis with the shroud and the impeller; and a plurality of pillars coupling the motor to the shroud, wherein the pillars secure the shroud in close proximity to the impeller. Various design features of the pump may be optimized to reduce hemolysis, such as, but not limited to, inlet length, impeller design, pillar angle, and outlet design.

  • Patent number: 10682452
    Abstract: The invention relates to an apparatus for exchanging material between blood and a gas/gas mixture, comprising a chamber (1) through which blood can flow and in which a plurality of material-permeable fiber tubes is provided, the gas/gas mixture being flowable through the fiber tubes, blood being flowable around the fiber tubes. At least one deformable element (9) is provided in the chamber (1) in addition to the fiber tubes, through which the gas/gas mixture can flow, this deformable element being deformable and restorable, in particular compressible out of a relaxed shape and restorable to a relaxed shape by pressure fluctuations acting on the at least one element (9) externally, in particular pressure fluctuations transmitted by the blood in the chamber (1).

  • Publication number: 20180147332
    Abstract: The invention relates to a system for ventricular circulatory support, comprising a device (2) for applying a magnetic field to a magnetised body fluid (1), particularly blood, in a region of a vessel (3), particularly a blood vessel. The system also comprises a control device designed to actuate said device (2) for applying a magnetic field such that, in the region of the vessel (3), a magnetically-induced force acts on the magnetised body fluid (1) in the longitudinal direction of said vessel (3).

  • Patent number: 9956380
    Abstract: The invention relates to a blood cannula for discharging blood into a vessel, in particular aortic cannula for discharging blood into an aortic arch during heart-bypass surgery, comprising a tubular body (1), the tubular body having a straight part at the proximal end (2) and a bent part at the distal end (3) leading into an outlet opening (5), wherein the distal end (3), in particular the bent part has an increasing cross section in the direction of blood flow (B).

  • Patent number: 9085316
    Abstract: A learning function is configured to determine a plurality of piecewise linear function coefficients based on measured data for an electric power-assisted steering (EPS) system. The measured data include a vehicle speed. The learning function is further configured to model a hysteresis loop of the EPS system using a piecewise linear function based on the plurality of piecewise linear function coefficients to determine an average friction. An average friction change compensator is configured to adjust friction-based EPS system compensation based on the average friction for a plurality of vehicle speed intervals of the vehicle speed.
