A model of flow through a left ventricular assist device (LVAD) can be used for preoperative planning of implantation of the LVAD into a patient and/or optimization of the LVAD after implantation into the patient are described. At least one imaging data set related to a patient and at least one physiological data set related to the patient can be received. An ideal parameter related to the LVAD can be determined based on the at least one imaging data set related to the patient, the at least one physiological data set related to the patient using a model of circulation in a large spatial region of the patient's body and a three-dimensional anatomical model of at least one component of the region of the patient's body and at least one component of the LVAD. Flow patterns within the three-dimensional anatomical model are calculated using computational fluid dynamics.

A system for treating a patient with a heart condition includes an atrial assist device (AAD) configured to be positioned in the patients heart to pump blood from an atrium of the patients heart into a ventricle associated with the atrium. The system also includes a controller operatively connected to the AAD and being configured to control the AAD to pump blood from the atrium of the patients heart into the ventricle associated with the atrium.

A deaerating device set allows a priming circuit to be deaerated fully automatically using a deaerating unit and a priming control unit, a priming liquid container and preferably a priming pump or a priming compressor. A blood pump is operated in a pulsatile manner during the pumping of a priming fluid.

Methods for synchronizing the actions of a pulsatile cardiac assist device with a dysfunctional heart using a cardiac pacemaker. Aspects include receiving a signal from the pacemaker and actuating the pulsatile cardiac assist device in response to the signal from the pacemaker to either help push blood out of the heart during systole or to help suck blood from the atria during diastole.

A hemodynamic flow assist device includes a miniature pump, a basket-like cage enclosing and supporting the pump, and a motor to drive the pump. The device is implanted and retrieved in a minimally invasive manner via percutaneous access to a patient's artery. The device has a first, collapsed configuration to assist in implantation and a second, expanded configuration once deployed and active. The device is deployed within a patient's aorta and is secured in place via a self-expanding cage which engages the inner wall of the aorta. The device includes a helical screw pump with self-expanding blades, sensors, and anchoring structures. Also disclosed is a retrieval device to remove the hemodynamic flow assist device once it is no longer needed by the patient and an arterial closure device to close the artery access point after implantation and removal of the hemodynamic flow assist device. The hemodynamic flow assist device helps to increase blood flow in patients suffering from congestive heart failure and awaiting heart transplant.

The invention concerns a control device for controlling a blood flow of an intravascular blood pump for percutaneous insertion into a patient's blood vessel, the blood pump comprising a pump unit with a drive unit for driving the pump unit and configured to convey blood from a blood flow inlet towards a blood flow outlet, wherein the control device is configured to operate the blood pump in a selectable zero-flow control mode, wherein a blood flow command signal is selected, and the control device comprises a first controller and a second controller, wherein the first controller is configured to control the blood flow by adjusting a speed command signal for the drive unit, and the second controller is configured to control a drive speed of the drive unit.

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.
