Patent number: 12251549Abstract: A blood pump for supporting the heart may be provided that includes: a rotor with delivery elements; a rotor drive; a pressure sensor; and a regulating device that regulates a pressure or a hemodynamic parameter by means of control of the rotor drive. The pressure and/or the hemodynamic parameter may be determined by means of one or a plurality of hemodynamic sensors and/or from operating parameters of the pump. The regulating device may be suitable for regulating a hemodynamic parameter successively, such as periodically, to different target values. Using such regulation, the blood pump may be operated in an optimized manner, and operation of the blood pump may be varied in a targeted and patient-protective manner in order to attain certain goals.Type: GrantFiled: July 21, 2023Date of Patent: March 18, 2025Assignee: Berlin Heart GmbHInventor: Marcus Granegger

Patent number: 11959497Abstract: Methods and apparatuses for determining operational parameters of a blood pump comprising a rotor which transports the blood are provided. The change in the behaviour of at least one first and one second operational parameter, independently from each other, of the pump, is determined. A determination of the flow through the pump and/or the difference in pressure across the pump and/or the viscosity of the blood takes into account the determined change in behaviour of the at least two operational parameters. A modelling for a dynamic model of the known quantities may be carried out and an estimation method using a Kalman filter may be used.Type: GrantFiled: June 28, 2021Date of Patent: April 16, 2024Assignee: Berlin Heart GmbHInventors: Marcus Granegger, Robert Steingräber, Jonas Fabian Krone
