Computer-aided Design and Manufacturing of a Patented, Left Ventricle Assist Device Positioning Tool – 3D Navigated Surgical Treatment of End-Stage Heart Failure

Abstract

The Left Ventricular Assist Device (LVAD), is a leading therapy option for patients with end-stage heart failure. A successful LVAD implantation is influenced by various factors, which are difficult or impossible to control during the operation. For optimal functioning of the device, its axis should be close to parallel with the septum, facing the mitral valve within the left ventricle. Our aim is to provide an innovative solution for these problems, using 3D technology and 3D printing. In our work, the production of the patented exoskeleton and the validation of its volumetric and surface quality, was presented, by comparing the virtual and 3D printed exoskeletons.
