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: 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.

Abstract: A cardiac assist system having a pumping device for moving blood, wherein a pumping capacity of the pumping device is adjustable using an adjustment signal based on laser doppler with an optical fiber. A measuring device measures a flow rate of the body fluid, the measuring device comprising at least one light source for outputting a light beam and at least one sensor element for detecting a reflected partial beam of the light beam. The measuring device is adapted to measure the body fluid using the reflected partial beam of the light beam. A determination device is adapted to determine the adjustment signal using the measurement signal. The device may include a bore opening to a blood flow channel, with an optical fiber extending through the bore.

Abstract: Disclosed is a mechanical circulatory support system for transcatheter delivery to the heart, having a removable guidewire aid to assist with inserting the guidewire along a path that avoids a rotating impeller. The system may comprise a catheter shaft and a circulatory support device carried by the shaft. The device may comprise a tubular housing, an impeller and the guidewire aid. The guidewire aid may include a removable guidewire guide tube. The guide tube may enter a first guidewire port of the tubular housing, exit the tubular housing via a second guidewire port on a side wall of the tubular housing on a distal side of the impeller, enter a third guidewire port on a proximal side of the impeller, and extend proximally through the catheter shaft.
