Heart assist system
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.
1. A supplemental blood flow system for assisting with blood circulation in a patient, the system comprising:
a supplemental blood flow device implantable in the patient,
a controller configured to direct electrical power to the supplemental blood flow device and controlling the flow rate of blood through the device, the controller having first and second power inlets and a power outlet, the power outlet adapted to be coupled to an electrical line leading to the supplemental blood flow device,
a portable programming module coupled to the first power inlet and configured to allow pump operating parameters stored in the controller to be changed according to the needs of the patient, and
at least one power supply unit configured to be coupled to the first and second power inlets, the at least one power supply unit including a power adaptor coupled to the portable programming module and a battery coupled to the second power inlet, wherein the power adaptor supplies power to the portable programming module, through the portable programming module and the first power inlet to the controller, and through the controller and the second power inlet to the battery, to thereby charge the battery with power supplied through the controller.
2. The system of claim 1 , wherein the at least one power supply unit comprises first and second power supply units capable of being electrically connected to the first and second power inlets.
3. The system of claim 2 , wherein at least one of the first and second power supply units may be electrically connected to the programming module.
4. The system of claim 2 , wherein the first and second power supply units respectively comprise first and second batteries.
5. The system of claim 2 , wherein one of the first and second power supply units comprises an AC to DC adaptor.
6. The system of claim 2 , wherein one of the first and second power supply units comprises a DC to DC adaptor.
7. The system of claim 1 , wherein the controller is capable of one way data transmission to a computer.
8. The system of claim 7 , wherein the controller includes a wireless transmitter for effecting the data transmission.
9. The system of claim 4 , wherein the controller is operative to sense when the first battery is not supplying adequate electrical power and, as a result, direct electrical power from the second battery to the supplemental blood flow device.
