Method and apparatus for providing safe long-range telemetry with implantable medical devices
First Claim
1. A method, comprising:
- detecting a predetermined condition evidencing an active telemetry session between an IMD and a programmer;
setting a timer to a predetermined time interval whenever the predetermined condition is detected;
initiating a telemetry termination operation if the timer expires prior to detecting a subsequent predetermined condition, the telemetry termination operation comprising;
setting a timer to a second time interval;
displaying a user notification message of an impending telemetry termination;
initiating a low-output mode of IMD telemetry circuitry that maintains a low-output telemetry link between the IMD and the programmer; and
terminating the telemetry link between the IMD and the programmer upon expiration of the second time interval.

Abstract
An implantable medical device (IMD) communication system and associated method for controlling the telemetry link status between an IMD and associated programmer during a telemetry session are provided. The system includes control circuitry for detecting conditions during predetermined time intervals for determining if a telemetry session is active or inactive. If a telemetry session is determined to be inactive for a specified interval of time, the telemetry link may be terminated or converted to a low-output, stand-by mode. Patient or device identity verification may be required prior to allowing programmer-IMD communication. A patient alert signal may be generated in response to programmer-IMD communication occurring after a predetermined time of telemetry session inactivity.

4. An implantable medical device communication system, comprising:
-
means for detecting an active telemetry session between an IMD and a programmer; means for resetting a timer to a predetermined time interval whenever the detecting means detects an active telemetry session; means for terminating the high-output mode of a telemetry link between the IMD and programmer when the predetermined time interval expires; means for setting a second timer to a second predetermined time interval upon initiating a stand-by low-output telemetry link when said predetermined time interval of the first timer expires; and means for terminating the stand-by low-output telemetry link upon expiration of the predetermined second time interval. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A computer-readable medium containing instructions that when implemented in an IMD system cause the system to:
-
detect predetermined conditions evidencing an active telemetry session between the IMD and a programmer; set a timer to a predetermined time interval in response to the detection of an active telemetry session condition; terminate a high-output telemetry link between the IMD and the programmer upon expiration of the timer; set a second timer to a second predetermined time interval initiate a stand-by low-output telemetry link when said predetermined time interval of the first timer expires; and terminate the stand-by low-output telemetry link upon expiration of the predetermined second time interval. - View Dependent Claims (15, 16, 17, 18)

19. A method, comprising:
-
detecting a predetermined condition evidencing an active telemetry session between an implantable medical device (IMD) and a programmer; setting a first timer to a first predetermined time interval and setting a second timer to a second predetermined time interval longer than the first predetermined time interval when the predetermined condition is detected; maintaining a high-output mode of IMD telemetry circuitry during the first and second predetermined time intervals; displaying a user instruction upon expiration of the first timer if the programmer receives user input during the second predetermined time interval that requires communication between the programmer and the IMD; resetting the first timer to the first predetermined time interval and the second timer to the second predetermined time interval upon receiving user input in response to the displayed user instruction; terminating the high-output mode of the IMD telemetry circuitry upon expiration of the second predetermined time interval; and initiating a low-output mode of IMD telemetry circuitry that maintains a low-output telemetry link between the IMD and the programmer upon expiration of the second predetermined time interval. - View Dependent Claims (20, 21, 22, 23)
