Key result
The MedTech Dispo Model 1 centrifugal blood pump with a 250 micro m clearance and polished surface yielded a normalized index of hemolysis of less than 0.001 g/100 L, 1/5 of the Biopump BP-80.
Why the study?
Does the MedTech Dispo Model 1 magnetic levitated centrifugal blood pump reduce hemolysis compared to conventional blood pumps in an in vitro porcine blood model?
Does the MedTech Dispo Model 1 magnetic levitated centrifugal blood pump reduce hemolysis compared to conventional blood pumps in an in vitro porcine blood model?
A novel magnetic levitated centrifugal blood pump demonstrated very low hemolysis levels in an in vitro porcine blood model, outperforming conventional mechanical bearing pumps.

Hoshi et al. (2006) studied this question. MedTech Dispo Model 1 centrifugal blood pump system vs. Biopump BP-80 and BPX-80 was evaluated on Normalized index of hemolysis (NIH). The MedTech Dispo Model 1 centrifugal blood pump with a 250 micro m clearance and polished surface yielded a normalized index of hemolysis of less than 0.001 g/100 L, 1/5 of the Biopump BP-80.
