Trial‐Based Hemolysis Modeling to Investigate Operating Modes of Continuous‐Flow LVADs

Artificial Organs, EarlyView.
This work presents a methodology for determining online‐capable hemolysis models for continuous‐flow LVADs, derived from in vitro trials. The models are based on fitting a modified power law and applying the Lagrangian approach. They assist clinicians in selecting treatment strategies that minimize hemolysis, as demonstrated with the Sputnik1 LVAD ...

Vasoreactivity as a Measure of Kidney Viability During Ex Vivo Normothermic Machine Perfusion

Artificial Organs, EarlyView.
This study aimed to investigate the influence of warm ischemic injury on renal vascular responsiveness to vasoactive drugs during normothermic machine perfusion (NMP). We found that the vascular responses to dopamine and norepinephrine could be used as objective indicators to assess kidney viability during NMP.

Optimizing Donor Kidneys During Normothermic Machine Perfusion With Sevoflurane: Design of a Research Model

Artificial Organs, EarlyView.
A stable kidney normothermic machine perfusion model with sevoflurane delivery via a vaporizer was established, enabling mechanistic and therapeutic studies of ischemia–reperfusion injury. ABSTRACT Normothermic machine perfusion (NMP) of donor kidneys provides an opportunity not only for organ preservation but also for therapeutic intervention to ...

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

Artificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.
