Abstract

A connector assembly for coupling to an implantable medical device includes a core element formed of a first thermoplastic material shaped to receive a connector member for receiving a lead. The connector assembly further includes a circuit member positioned adjacent to the core element. The circuit member includes a portion extending along the core element to the connector member and an antenna structure extending over a portion of the core element outer surface.

Claims

1. A connector assembly to be coupled to an implantable medical device, comprising:

a core element formed of a first thermoplastic material shaped to receive a connector member for receiving a lead, the core element having an outer surface;

a circuit member positioned adjacent to the core element, the circuit member including a portion extending along the core element to the connector member and including an antenna structure extending over a portion of the core element outer surface; and

an overmold portion formed of a second thermoplastic material to extend over and adhere to the core element.

2. The connector assembly of claim 1 wherein the antenna structure includes a curve portion corresponding to the portion of the core element outer surface.

3. The connector assembly of claim 1 wherein the core element outer surface comprises a first major side, a second major side and a curvilinear minor side separating the first major side and the second major side and wherein the antenna structure extends along the curvilinear minor side.

4. The connector assembly of claim 1 wherein the core element outer surface comprises a first flange and a second flange and wherein the antenna structure extends between the first and second flanges.

5. The connector assembly of claim 1 wherein the antenna structure is a wire member antenna.

6. The connector assembly of claim 5 wherein the antenna structure is formed having a free end, a fixed end, a first turn, a first segment extending between the free end and the first turn, a final turn, and a final segment extending from the final turn substantially parallel to the first segment.

7. The connector assembly of claim 6 wherein the antenna structure includes a penultimate turn and a penultimate segment extending from the first turn to the penultimate turn substantially parallel to the first and second segments.

8. The connector assembly of claim 6 wherein the first turn having a first turn width and the final turn having a second turn width substantially equal to the first turn width.

9. The connector assembly of claim 6 wherein the first turn having a first turn width and the final turn having a second turn width greater than the first turn width.

10. The connector assembly of claim 7 wherein the antenna structure is formed in a flat coil structure corresponding to the first segment being positioned between the penultimate and final segments.

11. The connector assembly of claim 7 wherein the antenna structure is formed in an elongated serpentine structure corresponding to the penultimate segment being positioned between the first and final segments.

12. The connector assembly of claim 1 wherein the core element outer surface comprises a first major side, a second major side and a curvilinear minor side separating the first major side and the second major side and wherein the antenna structure extends along one of the first major side and the second major side.
