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

Claim 18:
19. A medical device, comprising:
a memory circuit; and
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 separated 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; 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,
wherein the memory circuit is configured to store the determined spatial relationship;
wherein the calibration circuit is configured to receive subsequent acceleration information from the IMD, and to determine the orientation of the IMD or to calibrate the subsequent acceleration information using the stored determined spatial relationship to correct for the orientation of the IMD.
