Heart assist system
First Claim
1. A method of operating a supplemental blood flow system for assisting with blood circulation in a patient, the method comprising:
- directing electrical power to a supplemental blood flow device implanted in a patient through a controller electrically coupled to the supplemental blood flow device;
adjusting parameters of a pump associated with the supplemental blood flow device using a portable programming module coupled temporarily to the controller;
storing the parameters in the controller;
coupling at least one power supply unit to the controller;
coupling a battery to the controller;
supplying power to the portable programming module through the controller with the at least one power supply unit; and
supplying power to the battery through the controller with the at least one power supply unit to thereby charge the battery with power supplied through the controller.

Abstract
A supplemental blood flow system for assisting with blood circulation in a patient. The system includes a supplemental blood flow device implantable in the patient and a controller for directing electrical power to the supplemental blood flow device and controlling the flow rate of blood through the device. The controller includes first and second power inlets and a power outlet. The power outlet is adapted to be coupled to an electrical line leading to the supplemental blood flow device. A portable programming module may be coupled to at least one of the first and second power inlets and operable to allow pump operating parameters stored in the controller to be changed according to the needs of the patient.

10. A method of operating a supplemental blood flow system for assisting with blood circulation in a patient, the method comprising:
-
directing electrical power to a supplemental blood flow device implanted in a patient through a controller electrically coupled to the supplemental blood flow device, the controller including a power outlet coupled to the supplemental blood flow device and also including first and second power inlets; adjusting parameters of a pump associated with the supplemental blood flow device using a portable programming module coupled temporarily to the controller at one of the first and second power inlets; storing the parameters in the controller; controlling a flow rate of blood through the supplemental blood flow device by applying the parameters stored in the controller to operate the pump; coupling at least one power supply unit to the controller at the first power inlet; coupling a battery to the controller at the second power inlet; and supplying power to the battery through the controller with the at least one power supply unit to thereby charge the battery with power supplied through the controller, wherein power supplied to the battery from the at least one power supply unit is delivered from the at least one power supply unit and through each of the controller and the portable programming module before arrival at the battery. - View Dependent Claims (11, 12, 13, 14)
