1. A leadless cardiac pacemaker comprising:
- an elongated housing having a length, an energy storage section and a circuit section, the energy storage section defining a first volume that extends along a first fraction of the length of the elongated housing and the circuit section defining a second volume that extends along a second fraction of the length of the elongated housing, wherein the first faction does not overlap with the second fraction of the length of the elongated housing;
an energy source disposed within the first volume;
a circuit board disposed within the second volume but not in the first volume, the circuit board operably coupled to the energy source;
a first electrode and a second electrode each exposed along an exterior of the elongated housing and operatively coupled to the circuit board; and
an ID tag disposed on or in the energy storage section of the elongated housing, the ID tag configured to define a radiopaque manufacturer code that visually identifies a manufacturer of the leadless cardiac pacemaker.

Abstract
An implantable medical device includes a housing. A first ID tag is secured relative to the housing at a first position and defines a first radiopaque manufacturer code section that visually identifies a manufacturer of the implantable medical device. A second ID tag is secured relative to the housing at a second position that is offset from the first position in at least one dimension. The second ID tag defines a second radiopaque manufacturer code section that also visually identifies the manufacturer of the implantable medical device.

5. A leadless cardiac pacemaker, comprising:
-
an elongated housing extending along a central axis between a distal end and a proximal end; a distal electrode secured relative to the elongated housing; a proximal electrode secured relative to the elongated housing proximally of the distal electrode; fixation tines extending distally of the distal end of the elongated housing; a controller disposed within the elongated housing and configured to sense cardiac electrical signals via the distal electrode and the proximal electrode, and further configured to provide therapy to a patient'"'"'s heart via the distal electrode and the proximal electrode; and an ID tag system secured relative to the elongated housing, the ID tag system comprising a first radiopaque manufacturer code section that visually identifies a manufacturer of the leadless cardiac pacemaker and a second radiopaque manufacturer code section that also visually identifies the manufacturer of the leadless cardiac pacemaker, wherein the first radiopaque manufacturer code section and the second radiopaque manufacturer code section face different radial directions relative to the central axis of the elongated housing. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. A leadless cardiac pacemaker, comprising:
-
an elongated housing including a wall with an inside surface that defines an internal cavity, the inside surface of the wall having a shape; a pair of electrodes spaced apart and secured relative to the elongated housing; a controller disposed within the internal cavity defined by the wall of the elongated housing and operably coupled to the pair of electrodes; a power source disposed within the internal cavity defined by the wall of the elongated housing and operably coupled to the controller; and a radiopaque tag that is shaped to conform with the shape of the inside surface of the wall of the elongated housing, the radiopaque tag is further configured to define a radiopaque manufacturer code that visually identifies a manufacturer of the leadless cardiac pacemaker. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
