A blood pump (10) incorporates a blood lubricated journal bearing (82) that is characterized by a non-circular geometry (150). In one embodiment, the stationary bearing element, or stator, of the bearing is provided with a semi-elliptical shaped outer surface in an area opposite the load bearing film (104). The journal bearing configuration ensures that the blood flow therethrough is adequate, that the integrity of the blood is preserved and that bearing stability is maintained.

L'invention concerne une pompe à sang (10), comprenant un palier lisse lubrifié au sang (82), qui se caractérise par sa forme non circulaire (150). Dans un mode de réalisation, l'élément fixe, ou stator, dudit palier présente une surface extérieure de forme semi-elliptique, située à l'opposé du film du palier porteur (104). Le palier lisse est, de par sa configuration, traversé par un flux sanguin approprié, l'intégrité du sang étant préservée et la stabilité du palier maintenue.
