A controller for an implantable blood pump includes processing circuitry configured to initiate a suction response algorithm if a combination of a number of detected suction events multiplied by a suction event variable and a number of non-suction events multiplied by a non-suction event variable exceed a predetermined threshold.

A method of assisting a heart for the operation of a ventricular assist device comprising the steps of implanting a cannula to the heart and deploying a stent within a left ventricle, a right ventricle, a left atrium, or a right atrium of the heart. The stent may be transferable from a first compact configuration to a second open configuration to facilitate implantation. The stent may also have a flared distal end to assist with alignment, positioning, and prevent outgrowth.

A cassette integrated system. The cassette integrated system includes a mixing cassette, a balancing cassette, a middle cassette fluidly connected to the mixing cassette and the balancing cassette and at least one pod. The mixing cassette is fluidly connected to the middle cassette by at least one fluid line and the middle cassette is fluidly connected to the balancing cassette by at least one fluid line. The at least one pod is connected to at least two of the cassettes wherein the pod is located in an area between the cassettes.

A blood filtration system can reduce the amount of plasma constituents (e.g., water and/or electrolytes) in the blood of the patient, and accordingly increase the hematocrit value of the patient. The blood filtration system (e.g., a controller, or the like) can determine a hematocrit value of a patient. The blood filtration system can determine a venous pressure of vasculature of a patient. The blood filtration system can compensate for pressure head in a component of a blood circuit (e.g., a withdrawal line of a catheter), for example to improve the accuracy of the venous pressure determination. The blood filtration system can determine one or more resistance characteristics of a blood circuit for the blood filtration system. The resistance characteristics can correspond to a resistance to a flow of blood through a component of the blood circuit.

The systems, devices, and methods presented herein use a blood pump to obtain measurements of cardiac function. The system can quantify the functioning of the native heart by measuring certain parameters/signals such as aortic pressure or motor current, then calculate and display one or more cardiac parameters and heart function parameters, such as left ventricular pressure, left ventricular end diastolic pressure, or cardiac power output. These parameters provide valuable information to a user regarding current cardiac function, as well as positioning and function of the blood pump. In some embodiments, the system can act as a diagnostic and therapeutic tool. Providing cardiac parameters in real-time, along with warnings about adverse effects and recommendations to support cardiac function, such as increasing or decreasing the volumetric flow rate of blood pumped by the device, administering pharmaceutical therapies, and/or repositioning the blood pump allow clinicians to better support and treat cardiovascular disease.

The present disclosure pertains to control units for non-occlusive blood pumps of an extracorporeal circulatory support as well as systems comprising such a control unit and corresponding methods. Accordingly, a control unit for a non-occlusive blood pump of an extracorporeal circulatory support is configured to receive a flow value of the extracorporeal circulatory support, to receive a measurement of an arterial pressure and an ECG signal of a supported patient over a predetermined period of time, to determine a mean arterial pressure of the extracorporeal circulatory support or of the supported patient from the measurement of the arterial pressure and an energy equivalent pressure from the flow value and the arterial pressure.

An extracorporeal circulation management device pumps blood in synchronization with heartbeats of a patient based on measurements of blood flow. Maximum and minimum blood flow measurement samples are compared with upper and lower threshold values to identify candidate timing for a systolic phase and diastolic phase of the heartbeat. During pulsatile pumping of the blood using the candidate timing, differences in the pulsatile flow measurements are determined. Based on the size of the difference, a final correction may be made to identification of the systolic and diastolic phases, and the corrected phase information is used to start and stop the motor unit.
