Nichttraumatische Blutpumpe

摘要

A blood pump including a pumping chamber provided with in-flow and out-flow valves substantially aligned with the axis of the pumping chamber. The valves are especially designed to eliminate protrusions which may act as sites of possible thrombus formation, to minimize turbulence and areas of stasis and to provide a smooth flow of blood past the valve and through the pumping chamber. The inner lining of the pump includes a surface which contains microcavities to facilitate the attachment of fibrin and cellular deposits to provide a pseudointimal lining compatible with blood.
