Methods and devices for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. A method performed by the EI includes scanning one or more channels for an advertisement notice transmitted by the IMD in accordance with a scanning schedule, wherein the scanning schedule defines a temporal pattern of scanning windows that are separated by one or more scanning intervals. The method also includes changing the scanning schedule, in response to a duration of the scanning the one or more channels exceeding a predetermined threshold without a valid advertisement notice being received by the EI from the IMD, and scanning the one or more channels for the advertisement notice in accordance with the scanning schedule as changed, wherein the scanning schedule as changed defines a different temporal pattern of scanning windows that are separated by one or more scanning intervals.

Implantable medical device and method for managing advertising and scanning schedules

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.

Managing dynamic communication between implantable and external devices

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.

Implantable medical device with secure connection to an external instrument

Computer implemented methods and systems are provided that comprise, under control of one or more processors of a medical device, where the one or more processors are configured with specific executable instructions. The methods and systems include sensing circuitry configured to define a sensing channel to collect biological signals, memory configured to store program instructions, a processor configured to implement the program instructions to at least one of analyze the biological signals, manage storage of the biological signals or deliver a therapy, and communication circuitry configured to wirelessly communicate with at least one other implantable or external device, the communication circuitry configured to transition between a sleep state, a partial awake state and a fully awake state. When in the fully awake state, the communication circuitry is configured to execute tasks and actions associated with a communications protocol startup (CPS) instruction set that includes an advertisement scanning related (ASR) instruction subset and a non-ASR instruction subset. When in the partially awake state, the communication circuitry is configured to execute, as the ASR instruction subset, transmit advertising notices over one or more channels according to a wireless communications protocol, scan the one or more channels for a connection request from an external device. When a connection request is not received, return to the sleep state, without performing actions or tasks associated with the non-ASR instruction subset of the CPA instruction set.

System and method for managing Bluetooth Low Energy advertising

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.

Medical device and method for managing advertisement period

An implantable system includes an implantable medical device (IMD) and a non-transvenous lead that is configured to be implanted outside of a heart. The IMD includes an output configured to be connected at least to the lead, a current generator (CG) circuit configured to generate pacing pulses, a switching circuit coupled between the CG circuit and the output, one or more capacitors coupled in parallel with the CG circuit and the switching circuit, and a control circuit coupled to the CG circuit. The control circuit is configured to manage the CG circuit to generate the pacing pulses with a constant current at the output.

Method and implantable system for constant current pacing

Methods and devices for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The methods and devices comprise storing, in memory in at least one of the IMD or the EI an advertising schedule defining a pattern for advertisement notices. The advertisement notices are distributed un-evenly and separated by unequal advertisement intervals. The method transmits, from a transmitter in at least one of the IMD or the EI the advertisement notices. The advertisement notices are distributed as defined by the advertising schedule. The method establishes a communication session between the IMD and the EI.

Managing dynamic connection intervals for implantable and external devices

System and methods for establishing a communication session between an implantable medical device and an external device

A header-less implantable medical device, system and method are provided. The device includes an electronics module including circuitry, a battery, a receptacle assembly having an interior chamber and a receptable inlet configured to receive a lead connector assembly. A device housing has a case body that includes side walls and a peripheral edge that defines a single common chamber. The electronics module, battery and receptacle assembly are provided within the single common chamber. A connector opening is provided in the case body and joined to the receptacle inlet to form a passage through the case body into the interior chamber of the receptacle assembly.
