Abstract:
1. Device for axially conveying body fluids, comprising a tube-shaped hollow body transporting the fluids in an essentially axial manner, and in this hollow body there is arranged in axial alignment a conveying part that can be rotated by a motor stator located outside of the hollow body in a pump casing, where the conveying part has a rotor blading and where stationary inlet and outlet guide facilities are arranged in the direction of flow upstream and downstream of the conveying part, and inflow and outflow zones which are entirely coaxially aligned with the conveying part and positioned at opposite ends of the tube-shaped hollow body surrounding the inlet and outlet guide facilities, an intake bend made entirely of a flexible material leading from an inlet channel and having an intake bend angle, the intake bend being coupled to the inflow zone of the tube-shaped hollow body, the intake bend having a cross-sectional reduction in the direction of the inlet guide facility, and an outlet bend made entirely of a flexible material leading to an outlet channel is arranged having an outlet bend angle, the outlet bend being coupled to the outflow zone of the hollow body, wherein the intake and outlet bends flexible materials accommodate physical movements of the inlet and outlet channels when connected to a heart chamber or aorta.
