Abstract

In general, techniques are described for labeling an implantable medical device (IMD). In one example, an IMD can include a housing including electronic circuitry. The IMD can include a header coupled to the housing and includes a core. The core can define a bore and include a first metal label positioned adjacent to the at least one bore. The IMD includes a lead assembly including at least one lead having a distal end and a proximal end, the at least one lead including a second metal label, the distal end including at least one electrode and the proximal end received within the bore.

First claim

What is claimed is:

1. An implantable medical device, comprising:
a housing including electronic circuitry;
a header coupled to the housing and including a core, the core including:
a bore; and
a connector block opening in communication with the bore;
a receiving cavity positioned adjacent to the bore;
a window in communication with the receiving cavity;
a connector block positioned within the connector block opening and including a first identifier; and
a contact wire extending from the housing, the contact wire including the first identifier and configured to couple to the connector block.

2. The implantable medical device of claim 1 , wherein the first identifier is a color.

3. The implantable medical device of claim 1 , further including:
a metal label positioned within the first receiving cavity and including the first identifier.

4. The implantable medical device of claim 3 , wherein the first identifier on the metal label is visible through the window.

5. The implantable medical device of claim 4 , wherein the metal label is a first metal label, the device further including:
a lead including a second metal label including the first identifier, wherein the lead is configured to be electrically coupled to the electronic circuitry via the connector block and the contact wire.

6. An implantable medical device, comprising:
a housing including electronic circuitry;
a header coupled to the housing and including a core having a first face, a second face opposite the first face, a first side wall, and a second side wall opposite the first side wall, the core including:
a first bore extending from the first side wall toward the second side wall;
a first connector block opening in communication with the first bore;
a first receiving cavity extending from the first side wall toward the second side wall, the first receiving cavity positioned adjacent to the first bore; and
a first window extending from the first face to the receiving cavity such that the first window is in communication with the receiving cavity;
a first connector block positioned within the first connector block opening, wherein the first connector block includes a first identifier; and
a first contact wire extending from the housing, the first contact wire including the first identifier and configured to couple to the first connector block.

7. The implantable medical device of claim 6 , further including:
a first metal label positioned within the first receiving cavity adjacent to the first bore, wherein the first metal label includes the first identifier.

8. The implantable medical device of claim 7 , wherein the first identifier is a color.

9. The implantable medical device of claim 7 , wherein the core further includes:
a second bore extending from the first side wall toward the second side wall;
a second receiving cavity extending form the first side wall toward the second side wall, the second receiving cavity positioned adjacent to the second bore;
a second window extending from the first face to the receiving cavity such that the second window is in communication with the second receiving cavity; and
a second connector block opening in communication with the second bore.

10. The implantable medical device of claim 9 , further including:
a second metal label positioned within the second receiving cavity adjacent to the second bore, wherein the second metal label includes a second identifier;
a second connector block positioned within the second connector block opening, wherein the second connector block includes the second identifier, the second identifier different from the first identifier; and
a second contact wire extending from the housing, the second contact wire including the second identifier and configured to couple to the second connector block.

11. The implantable medical device of claim 10 , further including:
a lead assembly including a first lead and a second lead, wherein the first lead includes a first metal label including the first identifier and is configured to be electrically coupled to the electronic circuitry via the first connector block and the first contact wire, and the second lead includes a second metal label including the second identifier and is configured to be electrically coupled to the electronic circuitry via the second connector block and the second contact wire.

12. The implantable medical device of claim 10 , wherein the first metal label and the second metal label are chosen from at least one of titanium, tantalum, tungsten, and stainless steel.

13. The implantable medical device of claim 6 , wherein the core is overmolded with a dielectric material.

14. The implantable medical device of claim 6 , wherein the first receiving cavity has a first area that is greater than a second area of the first window.
