Leadless pacemaker with end-of-life protection
First Claim
1. A leadless cardiac pacing system, comprising:
- a first leadless pacing seed configured to deliver pacing therapy to a first location in a patient; and
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 provide 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 adapt to a change in an output from the second seed resulting from the second seed entering the end-of-life condition.

Abstract
A leadless cardiac pacing system includes first and second leadless pacing seeds configured to deliver pacing therapy to a first and second location in a patient, respectively. The second seed includes an electrode, a therapy circuit configured to provide electrostimulation energy to the electrode, a communications component, and a power source. The second seed also includes 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 the first seed to change from a first operational state to a second operational state, in which the first seed implements one or more operational parameters configured to adapt to a change in an output from the second seed resulting from the second seed entering the end-of-life condition.

19. A leadless cardiac pacing seed comprising:
-
an electrode configured to deliver electrostimulation energy to a first 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 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 seed entering the end-of-life condition. - View Dependent Claims (20)
