Assignee: CARDIAC PACEMAKERS, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 13:
14. A method, comprising:
receiving acceleration information sensed from an implantable medical device (IMD);
receiving reference acceleration information sensed from a reference device associated with a patient, the reference device separated from the IMD;
determining a spatial relationship between an orientation of the IMD and a reference orientation of the reference device using the received acceleration information and the received reference acceleration information;
acquiring subsequent acceleration information from the IMD;
determining the orientation of the IMD or calibrating the subsequent acceleration information using the determined spatial relationship to correct for the orientation of the IMD; and
generating a device diagnostic indicative of one or more of a rotation, a flip, or a migration of the IMD based at least in part on the determined orientation of the IMD.
