    摘要： Described herein are methods, devices and systems for efficiently storing data for sensed biological signals. A sensed biological signal, or an amplitude and/or filtered version thereof, is provided to an N-bit ADC of an IMD to produce an N-bit data value indicative of an amplitude of the biological signal at a point in time. One of a plurality of chords of a compression curve is selected, based on a magnitude of the N-bit data value, and used to produce an M-bit data value, which is a compressed version of the N-bit data value, wherein M

    摘要： 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.

    摘要： A method for operating an implantable medical device (IMD) implanted within a patient may include scanning for a wakeup request signal from an external programmer over a first frequency band at a first power level, switching to communication over a second frequency band at a second power level after the IMD detects the wakeup request signal, wherein the switching operation initiates an initial data exchange session during a common connected time period between the IMD and the external programmer, and cycling between the first and second power levels during the common connected time period based on whether data is being exchanged between the external programmer and the IMD.

    摘要： 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.
