1. A leadless cardiac pacemaker (LCP) configured to pace a patient'"'"'s heart, the LCP disposable within a chamber of the patient'"'"'s heart, the LCP comprising:
- a housing;
a plurality of electrodes secured relative to the housing;
two or more inductive coils secured relative to the housing, wherein each of the two or more inductive coils includes a plurality of windings extending about a central axis, wherein the central axis of one of the two or more inductive coils is not coaxial and not parallel with the central axis of another one of the two or more inductive coils;
a controller disposed within the housing and operably coupled to the plurality of electrodes and the two or more inductive coils, the controller configured to sense cardiac electrical activity of the patient'"'"'s heart via two or more of the electrodes and to generate and deliver pacing pulses via two or more of the electrodes; and
the controller is configured to communicate information between the LCP and one or more remotely located devices using;
conducted communication via two or more of the electrodes; and
inductive communication via one or more of the two or more inductive coils.

Abstract
Implantable medical devices such as leadless cardiac pacemakers may be configured to communicate using more than one mode of communication. For example, in some cases, an implantable medical device may be configured to communicate via conducted communication in some circumstances and to communicate via inductive communication in other circumstances. In some cases, the implantable medical device may be configured to switch between communication modes in order to improve communication.
