Abstract: The invention relates to a feed line (105) for a pump unit (110) of a cardiac support system (100). The feed line (105) is embodied to guide a fluid flow to a pump unit (110) of the cardiac support system (100). The feed line (105) comprises a feed head portion (130) with at least one introduction opening (140) for introducing the fluid flow into the feed line (105) and a contoured portion (135) with an inner surface contour. The contoured portion (135) is disposed adjacent to the feed head portion (130). An inner diameter of the contoured portion (135) at a first position is greater than the inner diameter at a second position. The inner surface contour has a rounded portion at the second position for reducing the inner diameter.

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 minimally invasive miniaturized percutaneous mechanical circulatory support system for transcatheter delivery of a pump to the heart that actively unloads the left ventricle by pumping blood from the left ventricle into the ascending aorta and systemic circulation. The pump may include a tubular housing, a motor, an impeller configured to be rotated by the motor. The impeller may be rotated by the motor, via a shaft with an annular polymeric seal around the shaft, or via a magnetic drive. The system may have an insertion tool having a tubular body and configured to axially movably receive the circulatory support device, and an introducer sheath configured to axially movably receive the insertion tool.

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.

Abstract: The invention relates to a bearing device (100) for a cardiac support system. The bearing device (100) comprises a stand unit (105) and an impeller (110). The stand unit (105) is designed to support the impeller (110) such that it can rotate. The impeller (110) is designed to rotate during an operation of the cardiac support system in order to convey a pump fluid flow (115). The impeller (110) is designed to enclose at least one subsection (120) of the stand unit (105) in the assembled state of the bearing device (100), wherein an intermediate space (125) for guiding a flushing fluid flow (130) is provided between the subsection (120) and the impeller (110). At least one flushing outlet (135) is formed in the impeller (110). The flushing outlet (135) is designed to discharge the flushing fluid flow (130) from the intermediate space (125) by means of centrifugal force when the cardiac support system is in operation.
