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, 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 bore extending from the first side wall toward the second side wall, and
a receiving cavity extending from the first side wall toward the second side wall, the receiving cavity positioned adjacent to the bore; and
a window extending from the first face to the receiving cavity such that the window is in communication with the receiving cavity;

a first metal label positioned within the receiving cavity adjacent to the bore, wherein the first metal label includes a first identifier; and
a lead assembly including a 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, wherein the second metal label includes a second identifier, the second identifier the same as the first identifier.

2. The implantable medical implant of claim 1 , wherein the first metal label and the second metal label are chosen from at least one of titanium, tantalum, tungsten, and stainless steel.

3. The implantable medical implant of claim 1 , wherein the first identifier and the second identifier include at least one of a color and text.

4. The implantable medical implant of claim 1 , wherein the first identifier is a first color and the second identifier is a second color, the second color and the first color being the same.

5. The implantable medical implant of claim 1 , wherein the first metal label is an anodized metal substrate.

6. The implantable medical implant of claim 5 , wherein a surface of the anodized metal substrate is textured.

7. The implantable medical implant of claim 1 , wherein the second metal label is an anodized metal annular ring.

8. The implantable medical implant of claim 1 , wherein the core is overmolded with a dielectric material.

9. The implantable medical implant of claim 1 , wherein the receiving cavity has a first area that is greater than a second area of the window.
