Journal ArticleDOI
Numerical Analysis of Blood Damage Potential of the HeartMate II and HeartWare HVAD Rotary Blood Pumps.
Bente Thamsen,Bastian Blümel,Jens Schaller,Christian Oliver Paschereit,Klaus Affeld,Leonid Goubergrits,Ulrich Kertzscher +6 more
TL;DR: An overall similar tendency to blood trauma in both pumps is indicated, however, influences of turbulent shear stresses were not considered and effects of the pivot bearing in the HM II were not taken into account, and further in vitro investigations are required.
Journal ArticleDOI
Blood Pump Design Variations and Their Influence on Hydraulic Performance and Indicators of Hemocompatibility.
Lena Wiegmann,Stefan Boës,Diane de Zélicourt,Bente Thamsen,M. Schmid Daners,Mirko Meboldt,Vartan Kurtcuoglu +6 more
TL;DR: A centrifugal blood pump is developed using industrial guidelines and its effects on hemodynamics and hydraulic performance using computational fluid dynamics and Eulerian and Lagrangian features, shear stress histograms and six indicators of hemocompatibility are analysed.
Journal ArticleDOI
Fluid Dynamics in the HeartMate 3: Influence of the Artificial Pulse Feature and Residual Cardiac Pulsation.
Lena Wiegmann,Bente Thamsen,Bente Thamsen,Diane de Zélicourt,Diane de Zélicourt,Marcus Granegger,Stefan Boës,Marianne Schmid Daners,Mirko Meboldt,Vartan Kurtcuoglu +9 more
TL;DR: Overall, it was found that viscous stresses in the HM3 were lower than in other current VADs, however, the artificial pulse substantially increased turbulence, and thereby also total stresses, which may contribute to clinically observed issues related to hemocompatibility.
Journal ArticleDOI
A two-stage rotary blood pump design with potentially lower blood trauma: a computational study.
Bente Thamsen,Ricardo Mevert,Michael Lommel,Philip Preikschat,Julia Gaebler,Thomas Krabatsch,Ulrich Kertzscher,Ewald Hennig,Klaus Affeld +8 more
TL;DR: Measured pressure-flow performance of the developed pump indicated its ability to generate adequate pressure heads and flows with characteristic curves similar to centrifugal pumps, and blood trauma might be reduced with this design.
Journal ArticleDOI
In vitro study of near-wall flow in a cerebral aneurysm model with and without coils.
Leonid Goubergrits,Bente Thamsen,André Berthe,J. Poethke,Ulrich Kertzscher,Klaus Affeld,Christoph Petz,Hans-Christian Hege,Heinrich Hoch,Andreas Spuler +9 more
TL;DR: It can be concluded that future hydrodynamic studies of coil therapy should include an investigation of the coil structure in addition to the coil-packing attenuation.
