Journal ArticleDOI
Energy Harvesting from the Beating Heart by a Mass Imbalance Oscillation Generator
Adrian Zurbuchen,Aloïs Pfenniger,Aloïs Pfenniger,Andreas Stahel,Christian T. Stoeck,Stijn Vandenberghe,Volker M. Koch,Rolf Vogel +7 more
TL;DR: An MRI-based motion analysis of the left ventricle revealed basal regions to be energetically most favorable for the rotating unbalance of the harvester and a mathematical model was developed as a tool for optimizing the device's configuration.
Journal ArticleDOI
Design of a new pulsatile bioreactor for tissue engineered aortic heart valve formation.
Kris Dumont,Jessa Yperman,Erik Verbeken,Patrick Segers,Bart Meuris,Stijn Vandenberghe,Willem Flameng,Pascal Verdonck +7 more
TL;DR: This study resulted in a prototype of a compact pulsatile flow system for the creation of TE aortic valves, with controllable resistance, compliance, stroke volume and frequency, and hydrodynamic conditions can be changed over a wide physiological range.
Journal ArticleDOI
A Novel Interface for Hybrid Mock Circulations to Evaluate Ventricular Assist Devices
Gregor Ochsner,Raffael Amacher,Alois Amstutz,André Plass,M. Schmid Daners,Hendrik Tevaearai,Stijn Vandenberghe,Markus J. Wilhelm,Lino Guzzella +8 more
TL;DR: A novel mock circulation for the evaluation of ventricular assist devices (VADs), which is based on a hardware-in-the-loop concept, to show the proper interaction between a numerical model of the circulation and a mixed-flow blood pump.
Journal ArticleDOI
Pulsatile control of rotary blood pumps: Does the modulation waveform matter?
TL;DR: A synchronized pulsing rotary blood pump offers a simple and powerful control modality for heart unloading and provides pulsatile hemodynamics, which is more physiologic than continuous blood flow and may be useful for perfusion of the other organs.
Journal ArticleDOI
Hemodynamic modes of ventricular assist with a rotary blood pump: continuous, pulsatile, and failure.
TL;DR: In pulsatile mode, unmatched heart and pulsatile pump rates yielded unphysiologic pressure and flow patterns and LV unloading was found to be highly dependent on synchronization phase, and a perfusion benefit can only be achieved if the continuous pump flow exceeds the preimplant (baseline) cardiac output.
