Patent number: 10589012Abstract: The invention relates to a blood pump for the invasive application within a body of a patient comprising a rotor (43, 27) which is drivable about an axis of rotation and is radially compressible or expandable and which has a hub (18, 28) and at least one impeller blade (14, 15, 16, 17, 29, 30) fastened thereto, as well as comprising a housing (19, 19?) which is compressible or expandable in the radial direction by an axial stretching or axial compression. The object of making both the rotor and the housing expandable and compressible in as simple a manner as possible is achieved in accordance with the invention in that a control body (21) is provided which passes through the hub (18) in the longitudinal direction, which is freely axially displaceable relative to the hub and which is coupled to the housing on the distal side of the rotor such that it exerts pulling and/or compression forces on the housing by a movement in the longitudinal direction with respect to the housing.Type: GrantFiled: November 17, 2017Date of Patent: March 17, 2020Assignee: ECP ENTWICKLUNGSGESELLSCHAFT MBHInventors: Thomas Toellner, Mario Scheckel

Patent number: 10584589Abstract: A rotor for a pump has a housing and a rotor, and has at least one blade. The rotor is able to be actuated to rotate about an axis of rotation in order to convey a fluid in the axial or radial direction, and the rotor is able to be deformed in the radial direction between a first, radially compressed state and a second, radially expanded state. At a maximum speed of rotation of the rotor at which the power of the pump is at a maximum, the blade is essentially radially oriented, and/or the rotor has its maximum diameter.Type: GrantFiled: August 8, 2017Date of Patent: March 10, 2020Assignee: ECP ENTWICKLUNGSGELLSCHAFT MBHInventors: Joerg Schumacher, Mario Scheckel
