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 invention relates to a method for determining a fluid volume flow (1) through an implanted vascular support system (2), comprising the following steps: a) determining a fluid temperature parameter in the region of a cannula (4) of the support system (2), b) operating a heating element (5) which can bring about a change in a fluid temperature in the cannula (4), c) determining the fluid volume flow (1) using at least the fluid temperature parameter or the change thereof and at least one heating element operating parameter or the change thereof. The invention also relates to a vascular support system.

Abstract: The invention relates to an apparatus (100) for anchoring a ventricular assist system in a blood vessel, the apparatus (100) being able to assume an insertion state for insertion of the ventricular assist system into the blood vessel, and the apparatus (100) being able to assume an anchoring state in order to anchor the ventricular assist system in the blood vessel. The apparatus (100) has at least one fixing means (105) for fixing the apparatus (100) to the ventricular assist system (205), a crown (110) and a connection means (115). The crown (110) is formed from at least one unfolding element (120). The unfolding element (120) is designed to unfold during the transfer from the insertion state into the anchoring state in order to enlarge the diameter of the crown (110) so as to anchor the apparatus (100) in the blood vessel. The connection means (115) is designed to connect the crown (110) to the fixing means (105).

Abstract: The invention relates to an apparatus (100) for attaching a cardiac support system to an insertion device, wherein the apparatus (100) is shaped to releasably couple the cardiac support system to the insertion device. The apparatus (100) has at least one main body (105), in particular a tubular main body (115), and a clamping device (110) with at least one clamping wing (115). The clamping device (110) is designed to mechanically couple the cardiac support system to the insertion device in an attachment state and to release the cardiac support system from the insertion device by displacing and/or flipping open the at least one clamping wing (115) in a release state.

Abstract: The invention relates to a line device (105) for conducting a blood flow for a heart support system. The heart support system has a head unit and an outlet unit. The line device (105) has a main part (205). The main part (205) has, at a first end, a first attachment section (210) for attaching the line device (105) to the head unit and, at a second end, a second attachment section (215) for attaching the line device (105) to the outlet unit. Furthermore, the main part (205) has a mesh section (220) between the attachment sections (210, 215), wherein the mesh section (220) has a mesh structure (230) formed from at least one mesh wire (225). In addition, the main part (205) has an inlet section (235), arranged in the first attachment section (210), for introducing the blood flow into the main part (205).

The line device (105) has a main part (205), and the main part (205) has a first attachment section (210) at a first end for attaching the line device (105) to a head unit of the heart support system and a second attachment section (215) at a second end for attaching the line device (105) to an outlet unit of the heart support system (100). The attachment sections (210, 215) are shaped so as to be connectable in a form-fitting and/or force-fitting manner. The main part (205) has a structured section (220) with at least one stiffening recess (225) between the attachment sections (210, 215), the at least one stiffening recess (225) being shaped so as to change the stiffness of the main part (205).

Abstract: The present application relates to an insertion sleeve (2), in which a guide wire (3) extends in order to guide the insertion sleeve (2). A cavity (23) is formed in the sleeve wall (22), which cavity extends in parallel with a longitudinal direction of the insertion sleeve (2) over the whole length of the sleeve, wherein said cavity (23) accommodates the guide wire (3). In addition to the cavity (23) at least one control wire (4) is integrated into the sleeve wall (22), which at least one control wire is designed to cause a curvature of the insertion sleeve (2).
