Abstract
The left ventricular assist device is based on the principle of the Maillard-Wenkel rotative pump. The materials which make up the pump must present particular mechanical, tribological, thermal and chemical properties. Graphite has been selected as a substrate, ceramic as the coating. The purpose of this study is to evaluate the in vitro complement activation eventually initiated by ceramic powders (A12O3, ZrO2/Y2O3, AIN, B4C, BN, SiC, Si3N4, TiB2, TiC, TiN), graphite and diamond. The morphology of powders has been studied by Scanning Electron Microscopy and X-Ray Diffraction investigations have been carried out. The evaluation of complement activation was undertaken by measuring the total hemolytic complement (CH50). No activation has been detected.
