Rate Responsive Leadless Cardiac Pacemaker
First Claim
1. A method of pacing a heart, comprising:
- sensing a parameter with a sensor of a leadless pacemaker implanted in the heart;
generating electrical pulses with a pulse delivery system of the leadless pacemaker;
delivering the electrical pulses through electrodes of the leadless pacemaker to stimulate the heart at least partly based on the sensed parameter; and
communicating encoded information signals to a device external to the leadless pacemaker through the electrodes of the leadless pacemaker.

Abstract
A leadless cardiac pacemaker comprises a housing, a plurality of electrodes coupled to an outer surface of the housing, and a pulse delivery system hermetically contained within the housing and electrically coupled to the electrode plurality, the pulse delivery system configured for sourcing energy internal to the housing, generating and delivering electrical pulses to the electrode plurality. The pacemaker further comprises an activity sensor hermetically contained within the housing and adapted to sense activity and a processor hermetically contained within the housing and communicatively coupled to the pulse delivery system, the activity sensor, and the electrode plurality, the processor configured to control electrical pulse delivery at least partly based on the sensed activity.

9. A method of operating pacemaker system, comprising:
-
sensing with a leadless pacemaker encoded electrical signals conducted through cardiac tissue; decoding and storing information in the encoded electrical signals; sensing a patient sensor signal within the pacemaker; converting the patient sensor signal to a rate-responsive pacing parameter as a function of the stored information; and controlling pacing pulse delivery as a function of the rate-responsive pacing parameter. - View Dependent Claims (10, 11, 12)

13. A method for operating a pacemaker comprising:
-
implanting a leadless cardiac pacemaker into cardiac tissue; measuring a patient signal with a patient sensor, the patient signal including an artifact signal resulting from cardiac muscle motion; sampling the patient signal synchronously with a cardiac cycle; monitoring the patient signal at identified points in the cardiac cycle; and removing the artifact signal from the patient signal based on the monitoring. - View Dependent Claims (14, 15, 16)
