An implantable medical device (IMD) may include a liquid crystal polymer (LCP) outer housing defining an outer surface of the IMD, circuitry disposed within the LCP outer housing, and an electrical feedthrough extending from a first end proximate the circuitry to a second end proximate to the outer surface. The electrical feedthrough may define a major axis extending between the first end and the second end, wherein the electrical feedthrough comprises non-uniform width measured in a direction along a plane substantially orthogonal to the major axis.
