Blood Damage in Ventricular Assist Devices [PDF]
The International Journal of Artificial Organs, 2016 Advancements in both the design of mechanical circulatory support (MCS) and medical care for recipients have led to steady improvements in patient survival over the last decades. Indeed, current generations of ventricular assist devices (VADs), for example, provide important therapeutic alternatives for individuals with heart failure that may be ...

Flexible Optoelectronic Hybrid Microfiber Long‐period Grating Multimodal Sensor
Advanced Science, EarlyView.An entirely new optoelectronic hybrid multimodal optical fiber sensor which can simultaneously monitor biomechanics and glucose is demonstrated. The developed method simultaneously integrates two heterogeneous sensing mechanisms, optical and electrical, into a single sensor in a compact manner. Optical and electrical sensors can work simultaneously but

Stochastic Modelling and Dynamic Analysis of Cardiovascular System with Rotary Left Ventricular Assist Devices [PDF]
Mathematical Problems in Engineering, 2018, 2018 The left ventricular assist device (LVAD) has been used for end-stage heart failure patients as a therapeutic option. The aortic valve plays a critical role in heart failure and its treatment with LVAD. The cardiovascular-LVAD model is often used to investigate the physiological demands required by patients and predict the hemodynamic of the native ...

Double‐Sided Conformable Piezoelectric Force Sensor with Enhanced Performance and Bending Correction
Advanced Electronic Materials, EarlyView.This work addresses the challenge of measuring low forces on soft surfaces. An innovative conformable piezoelectric force sensor is presented. The use of a highly flexible TPU substrate enables a tenfold increase in the sensor's sensitivity to compression while a double‐sided structure prevents the signal from being disturbed by bending due to ...

Eulerian Formulation of the Tensor-Based Morphology Equations for Strain-Based Blood Damage Modeling [PDF]
Computer Methods in Applied Mechanics and Engineering, Volume 426,
2024, 116979The development of blood-handling medical devices, such as ventricular assist devices, requires the analysis of their biocompatibility. Among other aspects, this includes hemolysis, i.e., red blood cell damage. For this purpose, computational fluid dynamics (CFD) methods are employed to predict blood flow in prototypes.
