1. An implantable medical device comprising:
- a feedthrough assembly coupled to an opening of a housing of the implantable medical device and partially extending from an interior of the housing to an exterior of the housing; and
a plurality of sensors circumferentially disposed within the feedthrough assembly within the portion of the feedthrough assembly partially extending to the exterior of the housing, wherein the plurality of sensors are configured to generate a directional signal as a function of an orientation and relative position of each of the plurality of sensors.

Abstract
A sensor is disposed within a pin portion of a feedthrough assembly. The feedthrough assembly provides a hermetically sealed enclosure that protects the sensor. In one embodiment, the sensor is a temperature sensor and the feedthrough assembly thermally isolates the sensor from the surrounding housing or enclosure.
