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: The invention relates to a motor housing module (110) for sealing a motor compartment of a motor of a heart support system. The motor housing module (110) has at least one feed-through portion (205), at least one feed-through line (210), and at least one contact pin (215). The feed-through portion (205) is designed to establish an electrical connection between the heart support system and a connection cable in order to externally contact the heart support system. The at least one feed-through line (210) is embedded in the feed-through portion (205) and extends through the feed-through portion (205). The feed-through line (210) can be connected to the motor and to the connection cable. A first end of the at least one contact pin (215) is embedded in the feed-through portion (205) and a second end of the contact pin (215) projects from the feed-through portion (205) on a side facing away from the motor compartment. The second end of the contact pin (215) can be connected to a sensor line to at least one sensor of the heart support system and to the connection cable.
