Abstract: The invention relates to a method for detecting a state of wear of a cardiac support system. The method comprises a read-in step and a determination step. During the read-in step, a sensor signal (315) representing an operating state of the cardiac support system is read in. During the determination step, a wear signal (325) is determined using the sensor signal (315) and a comparison rule (320). The wear signal (325) represents the wear condition.

Abstract: The approach presented here relates to an analysis device (100) for analyzing a viscosity of a fluid (217). The analysis device (100) comprises a detection device (110) and a provisioning device (115). The detection device (110) is formed to determine the viscosity of the fluid (217) using at least one Doppler parameter of a Doppler spectrum of the fluid (217). The provisioning device (115) is formed to provide or transmit a viscosity signal that represents the viscosity determined by the detection device (110).

Abstract: Disclosed is a minimally invasive miniaturized percutaneous mechanical circulatory support system. The system may be placed across the aortic valve via a single femoral arterial access point. The system includes a low profile axial rotary blood pump carried by the distal end of a catheter. The system can be percutaneously inserted through the femoral artery and positioned across the aortic valve into the left ventricle. The device actively unloads the left ventricle by pumping blood from the left ventricle into the ascending aorta and systemic circulation. A magnetic drive and encased motor housing allows for purgeless operation for extended periods of time to treat various ailments, for example more than six hours as acute therapy for cardiogenic shock.
