FEED LINE FOR A PUMP UNIT OF A CARDIAC ASSISTANCE SYSTEM, CARDIAC ASSISTANCE SYSTEM AND METHOD FOR PRODUCING A FEED LINE FOR A PUMP UNIT OF A CARDIAC ASSISTANCE SYSTEM

摘要

The invention relates to a feed line (105) for a pump unit (110) of a cardiac assistance system (100). The feed line (105) is embodied to guide a fluid flow to a pump unit (110) of the cardiac assistance 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 internal surface contour. The contoured portion (135) is disposed adjacent to the feed head portion (130). An internal diameter of the contoured portion (135) at a first position is greater than the internal diameter at a second position. The internal surface contour is rounded for the purposes of reducing the internal diameter at the second position.
