First Claim
Patent Images
1. A counterpulsation method of assisting the heart of a patient using a pump assist system, the method comprising:
- coupling a blood flow conduit to an artery of the patient, connecting a first port of a pulsatile pump to the blood flow conduit, implanting the pump in the patient at a location outside the chest cavity and abdominal cavity of the patient, connecting a power supply to the pump, positioning the power supply outside the body of the patient, and coordinating the operation of the pulsatile pump with the power supply to suction blood from the artery through the first port and the blood flow conduit while the heart is in systole and expel the blood into the first port and the blood flow conduit and the artery while the heart is in diastole.

7. A pump system for assisting the heart of a patient, comprising:
a pulsatile pump configured for implantation outside the chest cavity and the abdominal cavity of the patient, said pulsatile pump having a pump chamber, said pulsatile pump further including a port communicating with said pump chamber and said pump chamber including a movable element operative to suction blood into said pump chamber through said port and expel blood from said pump chamber through said port, a blood flow conduit coupled with said port and configured to be coupled to an artery of the patient, a power supply coupled to said pulsatile pump, and a control coupled with said pulsatile pump and coordinating the operation of said movable element to suction blood from the artery into said pump chamber through said port and said blood flow conduit while the heart is in systole and expel the blood from said pump chamber through said port and said blood flow conduit into the artery while the heart is in diastole. - View Dependent Claims (8, 9, 10)
