Patent ID: 11890101
Assignee: CARDIAC PACEMAKERS, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. A system, comprising:
a calibration circuit configured to:
receive acceleration information sensed from an implantable medical device (IMD);
receive reference acceleration information sensed from a reference device associated with a patient, the reference device separate from the IMD;
determine 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;
determine the orientation of the IMD or calibrate subsequent acceleration information sensed from the IMD using the determined spatial relationship to correct for the orientation of the IMD; and
generate 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.
