BLOOD FLOW SYSTEM WITH VARIABLE SPEED CONTROL

摘要

A fluid flow system for a patient is disclosed. A fluid drive module includes a fluid drive element (130), a housing (110), and a chamber (115) located between the housing (110) and the fluid drive element (130). A controller or control module (150) modifies the speed of the fluid drive element (130) during use, such as to prevent thrombus or otherwise improve flow conditions. Methods of alternating fluid flow are also provided.
