Abstract
A method and apparatus for sonication of blood to reduce Na.sup.+ K.sup.+ ATPase activity utilizes an extravascular sonication chamber and a blood pump to control the sonication parameters to prevent morphological damage to the blood cells. Secondary damage to surrounding tissues is avoided by sonicating the blood externally of the body. The sonicated blood may either be stored or returned directly to the body.
