  • Patent number: 11007370
    Abstract: A method is provided for establishing a communication session with an implantable medical device (“IMD”). The method includes configuring an IMD and an external device to communicate with one another through a protocol that utilizes a dedicated advertisement channel. The advertisement period and the scan period of the protocol are independent of one another such that the advertisement and scan periods at least partially overlap intermittently after a number of cycles. When the external device detects one of the advertisement notices, the method includes establishing a communications link between the external device and the IMD.

  • Publication number: 20210076312
    Abstract: An implantable medical device (IMD) that includes a transceiver configured to broadcast an advertising data packet that includes a unique identifier, and to receive a scan request data packet from an external device. A memory stores program instructions, and stores an approved device list, and one or more processors are configured to execute the program instructions to identify a device identifier (ID) from the scan request data packet received, apply an advertising filter to determine if the scan request data packet is from an authorized external device based on the device ID and the approved device list, based on the determination by the advertising filter, deny transmission of a scan response data packet from the transceiver when the advertising filter determines that the scan request data packet is from an unauthorized external device, and establish a communication session with an authorized external device independent of the scan request data packet.

  • Publication number: 20200344825
    Abstract: A method, system and external instrument are provided. The method initiates a communication link between an external instrument (EI) and an implantable medical device (IMD), established a first connection interval for conveying data packets between the EI and IMD and monitors a connection criteria that includes at least one of a data throughput requirement. A battery indicator or link condition of the communications link is between the IMD and EI. The method further changes from the first connection interval to a second connection interval based on the connection criteria.

  • 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.
