A control device for a heart pump, comprising a device for establishing the end-diastolic filling pressure in a ventricle and a device for associating a delivery rate of the pump, in particular a pump speed or an electric pump capacity, with the established end-diastolic filling pressure. By taking into account the end-diastolic filling pressure, a robust operating option of the heart pump, similar to the physio-logical control, is created.

Control device and method for a heart pump

A device for feeding a line through the skin of a patient, wherein the line contains a photodynamic substance that releases highly reactive oxygen derivatives when irradiated. Thus, disinfection/sterilization can be achieved in the region of a feed-through both on the outside of the skin and in the feed-through region by irradiating the feed-through.

Device for feeding a line through the skin of a patient

A method may be provided for the operation of a pump device, which comprises at least one pump as well as a suction element which is connected to the at least one pump and which has a suction opening positioned in a cavity of a body of a patient that sucks a fluid by way of producing a reduced pressure in the suction element, wherein an acceleration is measured and monitored during the operation of the pump device, wherein the reduced pressure in the suction element is reduced at least for a limited reaction time period, given the occurrence of an acceleration variable which lies above a fixed threshold valve. A correspondingly configured pump device may be provided.

Method for operating a pump device and a pump device

A heart pump and method for the operation of a heart pump are provided. A volume flow and an oxygen saturation may be determined by a sensor device. The sensor device including an oximeter configured to determine the oxygen saturation from blood. The oximeter may be fastened on the pump and include a ring on which a radiation source and a radiation sensor are fastened. Oxygen flow through the pump may be determined from the volume flow and the oxygen saturation. The heart pump may be controlled based on the oxygen saturation and/or the oxygen flow through the pump.

Implantable heart pump

The invention relates to a heart pump () with a delivery channel and with a delivery device () for blood, which is arranged in this delivery channel, wherein the delivery channel at least partly runs in a pump tube (). A first sensor device () for measuring the oxygen saturation of the blood, is provided on the heart pump, in particular on a wall of the delivery channel, in particular on the pump tube. A control device can also be integrated into the pump. Thereby, additional monitoring and control possibilities result.

Methods are provided for controlling the speed of a pump based on a valve state index and/or for deriving a valve state from time-series signal representing a pressure difference or a flow rate. The methods may be employed in blood pump systems or in blood pump control systems.
