Abstract:
1. A method of pacing a patient's heart, comprising: sensing a parameter with a sensor hermetically contained within a housing of a leadless pacemaker implanted in the heart, wherein the leadless pacemaker comprises a plurality of electrodes formed integrally to the housing or coupled to the housing at a maximum distance of 2 centimeters; generating electrical pulses with a pulse delivery system hermetically contained within the housing of the leadless pacemaker; delivering the electrical pulses through the electrodes of the leadless pacemaker to stimulate the heart at least partly based on the sensed parameter; generating encoded information signals within the leadless pacemaker; directly communicating the encoded information signals from the leadless pacemaker during a cardiac refractory period of the heart to a device external to the patient through the electrodes of the leadless pacemaker; and sourcing energy of no more than 75-80 microwatts instantaneously for generating the electrical pulses using a battery, wherein the peak power of the leadless pacemaker is less than or equal to 74 microwatts.
