A theoretical approach to the prediction of haemolysis in centrifugal blood pumps
… strongly depends on the extent to which they damage blood. The development of a theoretical pump evaluation model was performed in this study to facilitate an effective pump optimisation. The optimisation process seeks to maximise flow performance and minimise blood trauma which is primarily …

A novel magnetically levitated interior permanent magnet slice motor
… motor. This design is targeted for use as a blood pump in extracorporeal life support (ECLS) applications. A magnetically levitated blood pump reduces the risk of blood damage that frequently occurs at the blood seal in a conventional pump due to frictional heat generation.

Design of Percutaneous Dual Propeller Pump to assist Patients with Single Functional Ventricle
… the TCPC is developed and studied. The designed blood pump is percutaneously inserted via the Femoral vein and deployed at the center of Total Cavopulmonary Connection (TCPC). The two propellers, each placed in the Superior Vena Cava (SVC) and the Inferior Vena Cava (IVC) are connected by a …

Extracorporeal Circulation: Effect of Long-Term (24-Hour) Circulation on Blood Components
Extracorporeal circulation damages blood and causes harmful side effects such as stroke and/or systemic inflammatory response in patients. Reactions of blood components to extracorporeal circulation include complement and inflammatory reactions, coagulation and thrombogenesis, frank hemolysis, and …

Hemodynamic Optimization of a Passive Assist Total Cavopulmonary Connector for ages 1-20
… The 4-way connector was intended to channel the blood flow from the inferior and superior vena cava directly to the right and left pulmonary arteries. By creating a connector with proper hemodynamic characteristics, one can control the jet flow interactions between the inferior and superior vena …

Homopolar bearingless slice motors with magnet-free rotors for extracorporeal life support
… is a medical therapy that uses an external blood pump and oxygenator to provide cardiac or cardiopulmonary support. One common system-related challenge is to reduce blood damage, e.g., hemolysis, which is primarily caused by the stress and heat from the pump impeller's bearing surface. …

Application of passive flow control to mitigate the thromboembolic potential of bileaflet mechanical heart valves: an in-vitro study
… information was then used in numerical models of blood damage to predict the TEP of test heart valves using established platelet activation and platelet lysis parameters. BMHV leaflets were constructed using 3D printing technology with VGs based on micro-CT scans of a model BMHV leaflet. Two …

Bearingless Slice Motor and 6-DoF Position Sensor for Extracorporeal Pump
… for the bearingless motor is an extracorporeal blood pump. Extracorporeal blood pumps are used to maintain blood flow as a temporary ventricular assist device and/or blood oxygenator. Bearingless pumps can help to avoid blood damage caused by friction and heat generation due to seals and …
