1. A system comprising:
- an implantable medical device comprising a first tilt detector in a known orientation relative to at least a portion of the implantable medical device;
an orientation device comprising a second tilt detector; and
an indicator that provides information to a user based on signals from the first and second tilt detectors, wherein the information is indicative of a relative orientation between the orientation device and the portion of the implantable medical device,wherein the first tilt detector comprises a first accelerometer, andwherein the second tilt detector comprises a second accelerometer.

Abstract
Systems and methods for orienting a medical instrument relative to at least a portion of a medical device include a first tilt detector associated with the medical instrument and a second tilt detector associated with the medical device. The first tilt detector may be within an orientation device that is coupled to or separate from the medical instrument. The tilt detectors generate signals that may be used to determine the relative orientation between at least a portion of the medical device and medical instrument. For example, in some embodiments, the signals may be used to determine whether the orientations of the portion of the medical device and the medical instrument substantially match.
