Abstract

The present technology relates to power management for interatrial shunting systems. In some embodiments, the present technology includes a system for shunting blood between a left atrium and a right atrium of a patient. The system can include a shunting element and a plurality of active electronic components operably coupled to the shunting element. At least some of the active electronic components have different power consumption characteristics. The system also includes a plurality of energy storage components, with some of the energy storage components have different characteristics. During operation, the system is configured to receive a signal indicating that an active electronic component is to be operated, and select an energy storage component associated with power output characteristics capable of accommodating the power consumption characteristics of the active electronic component. The system is further configured to instruct the selected energy storage component to power operation of the active electronic component.

Claims (50)

1. A system for shunting blood between a left atrium and a right atrium of a patient, the system comprising:

a shunting element configured to be implanted in the patient;

a plurality of active electronic components carried by the shunting element, wherein at least some of the active electronic components have different power consumption characteristics;

a plurality of energy storage components operably coupled to the shunting element, wherein at least some of the energy storage components have different power output characteristics;

a processor; and

a memory storing instructions that, when executed by the processor, cause the system to perform operations comprising—

receiving a signal indicating that an active electronic component is to be operated, the active electronic component associated with power consumption characteristics,

selecting an energy storage component associated with power output characteristics capable of accommodating the power consumption characteristics of the active electronic component, and

instructing the selected energy storage component to power operation of the active electronic component.

2. The system of claim 1 wherein the plurality of active electronic components includes two or more of the following: a flow control mechanism, a communication device, a sensor, a memory, or a processor.

3. The system of claim 1 wherein the active electronic components include a first active electronic component having a power consumption greater than or equal to 1 W, and a second active electronic component having a power consumption less than or equal to 1 mW.

4. The system of claim 1 wherein the plurality of energy storage components includes at least one rechargeable energy storage component and at least one non-rechargeable energy storage component.

5. The system of claim 1 wherein the plurality of energy storage components comprises:

at least one of a primary battery or a second battery; and

at least one of a supercapacitor or a capacitor.

6. The system of claim 1 , further comprising a switching array configured to electrically couple the plurality of active electronic components and the plurality of energy storage components.

7. The system of claim 6 wherein the operations further comprise altering a configuration of the switching array to cause the selected energy storage component to power the operation of the active electronic component.

8. The system of claim 1 , further comprising an energy receiving component carried by the shunting element, wherein the energy receiving component is configured to receive power from a source external to the patient.

9. The system of claim 8 wherein the energy receiving component is operably coupled to at least one of the energy storage components to provide power thereto.

10. A method of operating an interatrial shunting system including a shunting element implanted in a patient's heart, the method comprising:

receiving, at a processor implanted in the patient's heart, a signal indicating that an active electronic component carried by the shunting element is to be operated, wherein the active electronic component has a set of power consumption characteristics;

selecting, via the processor, an energy source from a plurality of energy sources for powering the active electronic component, wherein at least some of the energy sources have different power output characteristics, and wherein the selected energy source has a set of power output characteristics capable of accommodating the power consumption characteristics of the active electronic component; and

powering operation of the active electronic component with the selected energy source.

11. The method of claim 10 wherein the active electronic component comprises a flow control mechanism, and wherein the method further comprises adjusting an amount of blood flow through the shunting element via the flow control mechanism.

12. The method of claim 10 wherein the active electronic component comprises a sensor, and wherein the method further comprises measuring a parameter of the patient or the shunting element via the sensor.

13. The method of claim 10 wherein the active electronic component comprises a communication device, and wherein the method further comprises transmitting data to a device external to the patient via the communication device.

14. The method of claim 10 wherein the plurality of energy sources includes at least one energy source external to the patient and at least one energy source implanted in the patient.

15. The method of claim 10 wherein the plurality of energy sources comprises two or more of: a primary battery, a secondary battery, a supercapacitor, or a capacitor.

16. The method of claim 10 , further comprising ranking the plurality of energy sources based at least in part on a priority algorithm.

17. The method of claim 16 wherein the ranking the plurality of energy sources comprises one or more of:

ranking energy sources having higher power density above energy sources having lower power density;

ranking rechargeable energy sources above non-rechargeable energy sources; or

ranking energy sources external to the patient above energy sources implanted in the patient.

18. The method of claim 10 wherein the energy source is selected based, at least in part, on historical data of at least some of the energy sources.

19. The method of claim 10 wherein the energy source is selected based, at least in part, on diagnostic data of at least some of the energy sources.

20. The method of claim 10 wherein the active electronic component is a first active electronic component and the selected energy source is a first energy source, and the method further comprises:

receiving, at the processor, a second signal indicating that a second active electronic component carried by the shunting element is to be operated, wherein the second active electronic component has a second set of power consumption characteristics different from the set of power consumption characteristics of the first active electronic component; and

selecting, via the processor, a second energy source from the plurality of energy sources for powering the second active electronic component, wherein the second energy source is different from the first energy source.

21. The method of claim 10 wherein the selected energy source is a first energy source, and the method further comprises:

selecting, via the processor, a second energy source from the plurality of energy sources; and

charging the first energy source with the second energy source before powering the operation of the active electronic component with the first energy source.

22. The method of claim 10 wherein the signal is received from a device implanted in the patient.

23. The method of claim 16 wherein the signal is received from a device external to the patient.

24. A system for shunting blood between a left atrium and a right atrium of a patient, the system comprising:

a shunting element configured to be implanted in the patient;

a plurality of active electronic components carried by the shunting element, wherein at least some of the active electronic components have different power consumption characteristics;

a plurality of energy storage components operably coupled to the shunting element, wherein at least some of the energy storage components have different power output characteristics;
