Temperature Sensor for a Leadless Cardiac Pacemaker
First Claim
1. A leadless cardiac pacemaker comprising:
- a hermetic housing adapted and configured to be disposed in a chamber of a human heart;
a battery disposed in the housing;
at least two electrodes supported by the housing;
a temperature sensor supported by the housing; and
a controller disposed in the housing and adapted to sense intracardiac information using the two electrodes and deliver stimulation energy from the battery to the electrodes using temperature information from the temperature sensor.

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 a temperature sensor hermetically contained within the housing and adapted to sense temperature information, wherein the pacemaker can control electrical pulse delivery at least partly based on the temperature information.
