PHYSIOLOGICAL HEART PUMP CONTROL

摘要

A blood pump (20) is joined in parallel flow between the left ventricle (16) and aorta (18) of a patient's heart (12). The pump (20) includes an inlet pressure sensor (22) and cooperating controller (30) for measuring inlet pressure to the pump to control operation thereof. The controller (30) adjusts speed of the pump (20) in a closed loop control (40) using feedback of the measured inlet pressure (P1) to conform operation of the pump with the natural cycle of the heart.
