摘要： A heart pump assembly, also referred to as catheter assembly, having a desired anatomical shape is provided. The catheter assembly can include a catheter and a cannula having a bend between a proximal portion and a distal portion. A resting shape of the catheter and the cannula can be selected to allow the distal cannula portion to be positioned at a desired angle relative to an anatomical plane (e.g., a plane of an aortic arch). In some embodiments, a packaging tray can be designed to set the catheter assembly in a desired resting shape. For example, the proximal cannula portion can be positioned at a first angle relative to the catheter, and the proximal cannula portion can be positioned at a second angle out of the plane of the packaging tray via one or more inserts.

摘要： The systems, devices, and methods presented herein use a heart pump to obtain measurements of cardiovascular function. The heart pumps described herein can operate in parallel with and unload the heart. The system can quantify the functioning of the native heart by measuring certain parameters/signals such as pressure or motor current, then calculate and display one or more metrics of cardiovascular function. These metrics, such as left ventricular end diastolic pressure (LVEDP), left ventricular pressure, and contractility, provide valuable information to a user regarding a patient's state of heart function and recovery.

摘要： A system and method for end-to-side anastomosis to an anatomical passageway is disclosed. The system and method are particularly useful in coupling an LVAD pump to an aorta. The system and method include using a tubular graft member having a skirt flange that engages the side of the aorta, a seating assembly and a flanged stent for securing the tubular graft to the side of the anatomical passageway. An assembly for creating an opening in the side of the anatomical passageway and an assembly for delivering the tubular graft is also disclosed.

摘要： Mechanical circulatory assist systems and related methods produce a pulsatile blood flow in synchronization with heart activity. A mechanical circulatory assist system includes a continuous-flow pump and a controller. The continuous-flow pump is implantable in fluid communication with a left ventricle of a heart of a patient and an aorta of the patient to assist blood flow from the left ventricle to the aorta. The controller includes a sensor that generates a signal indicative of an activity of the heart. The controller is operatively connected to the continuous-flow pump and configured to operate the continuous-flow pump in an artificial pulse mode in synchronization with the activity of the heart.

摘要： A method of estimating a patient's cardiac preload in a patient having an implantable blood pump. The method includes generating a current waveform from operation of the implanted blood pump. A beat-to-beat pump filling index (PFI) is calculated, the PFI is calculated by dividing a current amplitude component by a time component, the amplitude component being calculated by subtracting a trough of the current waveform from an inflection point divided by an amplitude difference of peak to trough of the waveform, the time component being calculated by dividing a time between the trough and the inflection point by a time between the peak and the trough. An alert is generated if the PFI deviates from predetermined thresholds.
