Abstract
An IMD may include a liquid crystal polymer (LCP) outer housing defining an outer surface of the IMD, an electrical feedthrough extending through the LCP outer housing to the outer surface, and an electrode structure disposed on the outer surface. The electrode structure may include a LCP substrate defining a first major surface and a second major surface substantially opposite the first major surface, a contact pad disposed on the first major surface, and an electrode disposed on the second major surface. The LCP substrate may be attached to the LCP outer housing and the contact pad may be electrically coupled to the electrical feedthrough.

An implantable medical device (IMD) comprising:
- a liquid crystal polymer (LCP) outer housing defining an outer surface of the IMD;
- an electrically conductive feedthrough extending through the LCP outer housing to the outer surface;
- and
- an electrode structure disposed on the outer surface, wherein the electrode structure comprises a LCP substrate defining a first surface and a second surface substantially opposite the first surface, a contact pad positioned on the first surface, and an electrode positioned on the second surface, and wherein the LCP substrate is attached to the LCP outer housing and the contact pad is electrically coupled to the electrically conductive feedthrough.
A method comprising:
- attaching an electrode structure to an outer surface of a liquid crystal polymer (LCP) outer housing, wherein the electrode structure comprises an LCP substrate defining a first surface and a second surface substantially opposite the first surface, a contact pad disposed on the first surface, and an electrode disposed on the second surface;
- and
- electrically connecting the contact pad to an electrically conductive feedthrough that extends through the LCP outer housing to the outer surface of the LCP outer housing.
