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