Abstract
Hemocompatible materials for the pump structures and for the surface coatings are explained. Anticoagulation materials with sufficient strength have been studied historically for a VAD application. The materials for implantable rotary VADs are mostly titanium or titanium alloys presently though short-term pumps are made of polymers. Bearing materials are also discussed comparing their wear characteristics.
