The ReinVAD LVAD: Smart Technology to Enhance Long-Term Circulatory Support Therapy

Rotary pumps have proven to represent the pumping principle of choice for chronic mechanical circulatory support. However, despite all the improvements in patient outcome, adverse events still limit the success and growth of the therapy. One option for improvement is new LVAD technology. As such, the ReinVAD LVAD is under development in a spin-off company from the Helmholtz Institute of the RWTH Aachen University, Germany. This chapter introduces into the design rationales of the system, and the chapter is divided into five main parts. Firstly, the system is introduced in terms of pump architecture and functionality. Secondly, the design choices to improve hemodynamic interaction with the circulation and corresponding research are illustrated. Thirdly, the closed-loop speed control algorithms based on the integrated flow sensor are briefly described. This is followed by a description of the driveline and safety mechanisms to reduce associated adverse events. Lastly, the system peripherals are introduced in combination with the increasingly important usability engineering process. In summary, the system’s features render this device uniquely adequate for enhanced long-term support for bridge to transplant patients and destination therapy patients.
