Abstract
Magnetic-based electronic valve readers for determining a location and orientation of magnets coupled to implantable medical devices to determine a setting of the device (e.g., setting of a fluid flow control valve of the medical device). The electronic valve readers include an orientation sensing mechanism that is provided and configured to enable the electronic valve reader to: 1) allow for internal offset calculation of an orientation change of the electronic valve reader during a reading process; and/or 2) during the reading process, provide an indication or warning to the clinician that the orientation of the electronic valve reader has changed to an extent at or exceeding a predetermined angular acceptance threshold or window. Systems including the disclosed electronic valve readers and methods of reading a setting of the device are also disclosed.
