  • Publication number: 20200383053
    Abstract: A method for managing power during communication with an implantable medical device, including establishing a communications link, utilizing a power corresponding to a session start power, to initiate a current session between an implantable medical device (IMD) and external device. A telemetry break condition of the communications link is monitored during the current session. The power utilized by the IMD is adjusted between low and high power levels, during the current session based on the telemetry break condition. The number of sessions is counted, including the current session and one or more prior sessions, in which the IMD utilized the higher power level, and a level for the session start power to be utilized to initiate a next session following the current session is adaptively learned based on the counting of the number of sessions.

  • Patent number: 10686878
    Abstract: Methods and systems are provided to manage display of cardiac signals. The methods and systems receive a first data steam along a first communications path conveyed with first throughput and receiving a second data stream along a second communications path transmitted with second throughput. The first and second throughputs are asynchronous with respect to one another. The first and second data streams carry cardiac signals sensed by external and implanted electrodes, respectively, for one or more common events. The methods and systems store data from the first and second data streams in first and second memory buffers. The methods and systems synchronize the data stored in the first and second memory buffers with one another by performing at least one of: temporally offsetting activation of the storing operation for the first and second data streams with respect to one another; or managing an amount of the data maintained in at least one of the first memory buffer or the second memory buffer.

  • Patent number: 10639482
    Abstract: A method and device for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The method stores, in a memory in at least one of the IMD or the EI, a base scanning schedule that defines a pattern for scanning windows over a scanning state. The method enters the scanning state during which a receiver scans for advertisement notices during the scanning windows. At least a portion of the scanning windows are grouped in a first segment of the scanning state. The method stores, in the memory, a scan reset pattern for restarting the scanning state. Further, the method automatically restarts the scanning state based on the scan reset pattern to form a pseudo-scanning schedule that differs from the base scanning schedule and establishes a communication session between the IMD and the EI.
