Leadless pacemaker with end-of-life protection

A leadless cardiac pacing system, comprising:

• a first leadless pacing seed configured to deliver pacing therapy to a first location in a patient;
• a second leadless pacing seed configured to deliver pacing therapy to a second location in a patient, the second leadless pacing seed comprising:
• an electrode configured to deliver electrostimulation energy to the second location;
• a therapy circuit configured to deliver the electrostimulation energy to the electrode;
• a communications component configured to send and receive communication signals;
• a power source configured to provide electrical energy to the therapy circuit and the communications component;
• and
• a power manager configured to detect an end-of-life condition associated with the second seed and, in response to detecting the end-of-life condition, to communicate a signal that causes the first seed to change from a first operational state to a second operational state, wherein when the first seed is in the second operational state, the first seed implements one or more operational parameters configured to compensate for a change in an output from the second seed resulting from the second seed entering the end-of-life condition;
• and
• an implantable control unit configured to control delivery of therapy by the first and second leadless pacing seeds.

A leadless cardiac pacing seed comprising:

• a therapy circuit configured to deliver the electrostimulation energy to the electrode;
• a communications component configured to send and receive communication signals;
• a power source configured to provide electrical energy to the therapy circuit and the communications component;
• and
• a power manager configured to detect an end-of-life condition associated with the seed and, in response to detecting the end-of-life condition, to communicate a signal that causes an additional seed to change from a first operational state to a second operational state, wherein when the additional seed is in the second operational state, the additional seed implements one or more operational parameters configured to adapt to a change in an output from the seed resulting from the second seed entering the end-of-life condition.
