A Sensorless Control System for an Implantable Heart Pump using a Real-time Deep Convolutional Neural Network [PDF]
IEEE Transactions on Biomedical Engineering, 2021, 2021 Left ventricular assist devices (LVADs) are mechanical pumps, which can be used to support heart failure (HF) patients as bridge to transplant and destination therapy. To automatically adjust the LVAD speed, a physiological control system needs to be designed to respond to variations of patient hemodynamics across a variety of clinical scenarios. These
