Thermal stimulation and subsequent cooling for fully implantable LVAD controller
A method of cooling a mammal with an implantable blood pump. The method includes measuring a temperature of an internal controller, the internal controller being in communication with the implantable blood pump. an alert is generated if the temperature of the internal controller exceeds a predetermined temperature threshold.
1. A system comprising:
an internal controller including a control circuit having processing circuitry, the internal controller configured to be implanted within a patient and configured to be in communication with an implantable blood pump; and
an external controller configured to be in communication with the internal controller and configured to determine a temperature of the internal controller, the external controller being configured to generate an alert if the temperature of the internal controller exceeds a predetermined temperature threshold.
2. The system of claim 1 , wherein the internal controller includes at least one temperature sensor configured to measure the temperature of the internal controller.
3. The system of claim 2 , wherein the internal controller is configured to communicate the measured temperature to the external controller, and wherein the external controller is configured to determine the temperature of the internal controller by at least receiving the measured temperature from the internal controller.
4. The system of claim 1 , wherein the alert instructs the patient with the implantable blood pump to place a heating pad on a back of a neck of a body of the patient.
5. The system of claim 1 , wherein the alert instructs the patient with the implantable blood pump to go to a hospital.
6. The system of claim 1 , wherein the predetermined temperature threshold is 39 degrees Celsius.
7. The system of claim 1 , wherein the predetermined temperature threshold is between 39 degrees Celsius and 43 degrees Celsius.
8. The system of claim 1 , wherein the predetermined temperature threshold is 43 degrees Celsius.
9. The system of claim 1 , wherein the alert instructs the patient with the implantable blood pump to thermally stimulate a back of a neck of a body of the patient.
10. The system of claim 1 , wherein the internal controller is physically separate from the implantable blood pump and is configured to control an operation of the implantable blood pump.
11. A system comprising:
an internal controller configured to be implanted within a patient and configured to be in communication with an implantable blood pump;
a temperature sensor coupled to the internal controller, the temperature sensor physically separate from the blood pump; and
an external controller configured to be in communication with the internal controller and configured to determine a temperature of the internal controller, the external controller being configured to generate an alert if the temperature of the internal controller exceeds a predetermined temperature threshold.
12. The system of claim 11 , wherein the alert instructs the patient with the implantable blood pump to place a heating pad on a back of a neck of a body of the patient.
13. The system of claim 11 , wherein the alert instructs the patient with the implantable blood pump to go to a hospital.
14. The system of claim 11 , wherein the predetermined temperature threshold is 39 degrees Celsius.
15. The system of claim 11 , wherein the predetermined temperature threshold is between 39 degrees Celsius and 43 degrees Celsius.
16. The system of claim 11 , wherein the predetermined temperature threshold is 43 degrees Celsius.
17. The system of claim 11 , wherein the alert instructs the patient with the implantable blood pump to thermally stimulate a back of a neck of a body of the patient.
18. The system of claim 11 , wherein the blood pump is electrically coupled to the internal controller by one or more implanted conductors.
19. The system of claim 11 , wherein the internal controller is coupled to an internal coil.
20. The system of claim 19 , wherein the internal coil is configured to be inductively powered by an external coil.
