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.

First claim

We claim:

1 . An implantable medical device for implantation within a body, comprising:
a housing; a first ID tag secured relative to the housing at a first position, the first ID tag defines a first radiopaque manufacturer code section that visually identifies a manufacturer of the implantable medical device; and a second ID tag secured relative to the housing at a second position, the second position 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.

2 . The implantable medical device of claim 1 , wherein the first radiopaque manufacturer code section and the second radiopaque manufacturer code section each define one or more radiopaque alphanumeric characters.

3 . The implantable medical device of claim 2 , wherein the one or more radiopaque alphanumeric characters are configured to be human readable in an x-ray image of the implantable medical device.

4 . The implantable medical device of claim 1 , wherein the first radiopaque manufacturer code section of the first ID tag is structured to define a first radiopaque manufacturer code as well as a reverse image of the first radiopaque manufacturer code.

5 . The implantable medical device of claim 1 , wherein at least one of the first ID tag and the second ID tag are disposed on an outer surface of the housing.

6 . The implantable medical device of claim 1 , wherein at least one of the first ID tag and the second ID tag are disposed on an internal component located within the housing.

7 . The implantable medical device of claim 1 , wherein the second position is offset from the first position in at least two dimensions.

8 . The implantable medical device of claim 1 , wherein the first ID tag and the second ID tag comprise portions of a helix structure traversing along at least part of a length of the housing.

9 . A leadless cardiac pacemaker comprising:
an elongated housing defining an energy storage section and a circuit section; an energy source disposed within the energy storage section; a circuit board disposed within the circuit section and operably coupled to the energy source; and an ID tag secured relative to the elongated housing, the ID tag configured to define a radiopaque manufacturer code that visually identifies a manufacturer of the leadless cardiac pacemaker.

10 . The leadless cardiac pacemaker of claim 10 , further comprising an insulative coating disposed over the elongated housing, and the ID tag is covered by the insulative coating.

11 . The leadless cardiac pacemaker of claim 9 , wherein the energy source comprises a battery liner, an anode disposed within the battery liner, and a cathode disposed within the anode, and the ID tag is disposed on or in one of the battery liner, the anode and the cathode.

12 . The leadless cardiac pacemaker of claim 26 , further comprising a battery pin extending from cathode of the energy source, wherein the ID tag is disposed on or in the battery pin.

13 . The leadless cardiac pacemaker of claim 9 , further comprising a desiccant, wherein the ID tag is disposed on or in the desiccant.

14 . The leadless cardiac pacemaker of claim 9 , further comprising an epoxy overmolding, wherein the ID tag is disposed on or in the overmolding.

15 . The leadless cardiac pacemaker of claim 9 , further comprising a drug collar, wherein the ID tag is disposed on or in the drug collar.

16 . The leadless cardiac pacemaker of claim 9 , wherein the elongated housing comprises a proximal end feature for retrieval of the leadless cardiac pacemaker, and the ID tag is secured to the proximal end feature.

17 . The leadless cardiac pacemaker of claim 9 , further comprising an axial rotation marker, and the ID tag is disposed within a cutout formed in the axial rotation marker.

18 . The leadless cardiac pacemaker of claim 9 , wherein the ID tag is formed from a platinum wire disposed within a slot formed in the elongated housing.

19 . A leadless cardiac pacemaker, comprising:
an elongated housing extending along a central axis; 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.

20 . The leadless cardiac pacemaker of claim 20 , wherein the ID tag system further comprises a first radiopaque Mill code section and a second radiopaque Mill code section, wherein the first radiopaque Mill code section and the second radiopaque Mill code section face different radial directions relative to the central axis of the elongated housing.
