PERKUTANE BLUTPUMPE MIT VEREINIGTEM AXIAL- UND RADIALSTRÖMUNGSDURCHSATZ.

摘要

The outside diameter of an intravascular axial flow blood pump is reduced without reducing the size of its journal bearings by causing the pumped blood stream to exit through apertures in the cylindrical outside wall of the pump housing between the rotor blades and the rotor journal. This allows the journal to have a diameter of the housing, without the need for a space-consuming blood flow path around the journal.
