Failsafe satellite pacemaker system
First Claim
1. An implantable failsafe pacemaker system comprising:
- a. a pacemaker comprising a lead adapted for implantation within a right side of a heart;
b. a plurality of wireless satellite pacemakers adapted for being mounted to a left side of the heart;
c. each of the plurality of satellite pacemakers being capable of sensing and delivering pacing pluses to the heart via at least one electrode; and
d. each of the plurality of wireless satellite pacemakers being adapted to detect an absence of a local pacing pulse from at least one of the other satellite pacemakers and to autonomously assume delivery of pacing pulse without conflicting with others of the plurality of pacemakers in response to the detection of the absence of a local pacing pulse.

Abstract
In one implementation, a failsafe method for implantable satellite pacemaker pacing is provided, which includes pacing with a satellite pacemaker and monitoring for a local pacing pulse with an other satellite pacemaker. This implementation further includes, pacing with a surrogate satellite pacemaker if the local pacing pulse is not detected by the other satellite pacemaker. Certain implementations may include transmitting a wireless signal from the other satellite pacemaker to a master pacemaker if the local pacing pulse is not detected by the other satellite pacemaker and using the master pacemaker to select the surrogate satellite pacemaker. Certain implementations may include monitoring for the local pacing pulse with a plurality of satellite and causing the plurality of satellite pacemakers to select the surrogate satellite pacemaker.
