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.
