The present technology provides a blood pump device and associated systems and methods of use thereof to assist blood circulation in a patient. The blood pump device includes a flexible member disposed within a housing. Movement of the flexible member in the housing varies the volume of chambers within the housing and effectuates pumping of blood to and from a vessel in fluid connection with a chamber of the blood pump device.

A heart pump assembly includes an elongate catheter with a proximal portion and a distal portion, a rotor at the distal portion of the elongate catheter, a driveshaft, and a bearing. The rotor can include an impeller blade shaped to induce fluid flow in a first axial direction. The drive shaft may be coupled to or integrally formed with a proximal end of the rotor and can include a pump element formed in a surface of the drive shaft. The bearing can include a bore into which the drive shaft extends. The pump element is shaped so as to induce fluid flow through the bore in a second axial direction which can be the same or opposite to the first axial direction.

A system for detecting a suction condition in an implantable blood pump including a controller in communication with the blood pump. The controller includes a control circuit configured to calculate a present value during a time period, the present value corresponding to a pump speed divided by a pump current, determine a plurality of data values during the time period based on the present value, and determine a suction detection threshold value using the plurality of data values. The control circuit is also configured to compare the present value during the time period to the suction detection threshold value and generate an alert when the present value exceeds the suction detection threshold value on a plurality of instances during the time period, the alert corresponding to a suction condition.

A method of determining adverse events from log file data from operation of an implantable blood pump. The method includes measuring a flow pulsatility from flow rate data recorded in a log file. A moving mean of the measured flow pulsatility is calculated. A moving standard deviation of the measured flow pulsatility is calculated. A difference between the moving mean of the measured pulsatility and the moving standard deviation of the measured flow pulsatility is calculated. If the difference is less than a first predetermined threshold, an alert is generated as the presence of an adverse event.

A method of fixating an implantable heart help device in a human patient is provided. The method comprises the steps of: cutting the skin of said human patient, dissecting an area of the body comprising bone, and fixating said implantable heart help device to said part of the body comprising bone.

Method and systems control a rotational speed of a blood pump during ventricular diastole. A method includes controlling a blood pump in accordance with a first segment operational mode. A controller monitors the blood flow rate through the blood pump. The controller determines, based on the blood flow rate, whether continued controlling of the blood pump per the first segment operational mode would result in the blood flow rate through the blood pump being less than a target minimum blood flow rate. In response to a determination that continued controlling of the blood pump per the first segment operational mode would result in the blood flow rate through the blood pump being less than the target minimum blood flow rate, the controller controls the rotational speed of the blood pump so that the blood flow rate through the blood pump is approximate to the target minimum blood flow rate.

The catheter device comprises a motor at the proximal end of the catheter device and a drive shaft, extending from the proximal end section to the distal end section of the catheter device, for driving a rotating element located at the distal end of the catheter device. The catheter device also comprises a hose-like catheter body which encompasses the drive shaft and extends from the proximal end section to the distal end section. At the proximal end of the catheter device, the drive shaft is connected to a motor by a clutch. The clutch is a magnetic clutch with a proximal and a distal magnet unit. The proximal magnet unit is connected to the motor and the distal magnet unit to the drive shaft. The distal magnet unit is mounted fluid-tight in a clutch housing. The proximal end of the catheter body makes a fluid-tight connection with the clutch housing.
