GHOST™ is produced with a complete polymer free technology to increase the biocompatibility. INERT-TECHNOLOGY Under vacuum carbon ions are shot with high load of energy in the metal structure, so that the ions are implanted within the metal lattice under the alloy´s surface. BIOCOMPATIBILITY The Inert Technology creates a barrier for migrating heavy metal ions like chromium, nickel and molybdenum with direction to body cells. As clinical trials have proven the technology avoids metal provoked thrombosis and restenosis.
