1. A system comprising:
- an implantable medical device defining a longitudinal outer surface;
a stimulation electrode extending at least partially around the longitudinal outer surface of the implantable medical device; and
a wire fixation element disposed along the longitudinal outer surface of the implantable medical device, wherein only a portion of the fixation element is electrically conductive, the portion being configured to at least one of deliver electrical stimulation to a target tissue site within a patient or sense a physiological parameter from the target tissue site, wherein the fixation element is actively deployable from a first shape to a second shape to resist substantial movement of the implantable medical device from the target tissue site, and wherein the stimulation electrode and the portion of the fixation element are configured to be activated independent of one another.

Abstract
A system comprises an implantable medical device and an actively deployable clip attached to the implantable medical device to restrict movement of the implantable medical device once the clip is deployed within a body of a patient. The clip includes an electrically conductive portion. The implantable medical device may be implanted proximate to any suitable tissue site within the patient, and in one embodiment, the implantable medical device is implanted proximate to an occipital nerve or a trigeminal nerve of the patient.

35. A system comprising:
-
an implantable medical device defining an outer surface; a stimulation electrode extending at least partially around the outer surface of the implantable medical device; and a fixation element coupled to the implantable medical device, the fixation element comprising an electrically conductive portion configured to at least one of deliver electrical stimulation to a target tissue site within a patient or sense a physiological parameter from the target tissue site, wherein the fixation element is actively deployable from a first shape to a second shape to resist substantial movement of the implantable medical device from the target tissue site, and wherein the first shape is a substantially straight shape and the fixation element does not protrude past the outer surface of the implantable medical device when deployed to the second shape.
