Disclosed is a method of adapting the operation of an implantable device for delivering neurostimulation therapy to a patient. The method comprises: delivering the neurostimulation therapy to electrically excitable tissue of the patient according to at least one therapy parameter; measuring a physiological characteristic of the patient; adjusting the at least one therapy parameter according to a schedule of adjustment and the measured physiological characteristic; and repeating the delivering, measuring, and adjusting.

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.

Aspects of the disclosure provide for a circuit, in some examples, including a storage element, a co-processor, and a telemetry sequencer coupled to the storage element and the co-processor. The telemetry sequencer is configured to implement a digital state machine to receive configuration information indicating a type of telemetry data for generation, retrieve operations and operands, where the operations and the operands define a sequential series of actions for execution to generate the telemetry data, drive the co-processor with the operations and the operands by passing some of the operations and some of the operands to the co-processor for processing by the co-processor, receive, from the co-processor, and store an intermediate output of the series of actions as the telemetry data in a first format, and receive, from the co-processor, and store a final output of the series of actions as the telemetry data in a second format.

An implantable medical device system is configured to sense cardiac events in response to a cardiac electrical signal crossing a cardiac event sensing threshold. A control circuit is configured to determine a drop time interval based on a heart rate and control a sensing circuit to hold the cardiac event sensing threshold at a threshold value during the drop time interval.

Systems and methods involving implants positioned within implant pockets through minimally invasive entrance incisions, along with related neurostimulatory implants. In some implementations, implants may be folded, rolled, or otherwise compressed to fit within subcutaneous implant pockets, after which they may be decompressed to fit within an implant pocket having one or more dimensions substantially larger than the entrance incision. Such implants may be used for a variety of purposes, including generating electrical energy for various other implants, including neurostimulatory implants located throughout the body.

Semi-autonomous vehicle apparatus which is controlled by a plurality of control sources includes a vehicle which may function autonomously and apparatus for control of the vehicle by either an onboard driver or a driver not situated onboard. The vehicle may also be controlled by an off-vehicle computational device. Hierarchy setting apparatus determines which one or combination of the possible control entities take priority. Persons using the apparatus are identified by either a password or, preferably by providing identification based on a biologic feature. Management of impaired vehicle operators is provided for.

A medical device for electrical stimulation therapy including an implantable lead with multiple levels of lead electrodes in a first segmented electrode configuration, at least one level of the lead electrodes comprising segmented electrodes. A flexible member is configured to be disposed over the first electrode segmented electrode configuration, the flexible member having a first inner side and a first set of member electrodes, at least some of the first set of member electrodes configured to be positioned to electrically contact corresponding lead electrodes of the first segmented electrode configuration. The flexible member having a second outer side and a second set of member electrodes in a second segmented electrode configuration which is different than the first segmented electrode configuration, at least some of the second set of member electrodes electrically coupled to corresponding member electrodes of the first set of member electrodes.

Embodiments herein relate to sensor based authentication between an implantable medical device (IMD) and an external device. In an embodiment, the IMD includes a wireless communication module and an internal inertial measurement unit (IMU) capable of measuring vibrations, movement, or rotation. The IMD is configured to record an internal IMU signal from the internal IMU. The external device includes a wireless communication module and an external IMU. The external device is configured to record an external IMU signal from the external IMU. The system further includes a data processing system to receive a first level communication that can include the internal IMU signal, the external IMU signal, or both, compare data from the internal IMU signal with data from the external IMU signal, and authorize a second level communication based on results of the comparison step.

Systems, devices, and methods for remote monitoring and managing of patients with chronic pain are discussed. A remote monitoring system comprises a cloud-computing device and a remote device. The cloud-computing device receives patient data including physiological or functional information sensed by sensors, and provides on-demand cloud-based services including establishing a correspondence between one or more physiological or functional states and one or more pain levels, detecting patient physiological or functional state, predicting a pain level, detecting a patient behavior, generating a recommendation for adjusting sensor operations based on the patient behavior, and storing patient data and other information in a cloud storage. The remote device can access the cloud storage and the cloud-based services, provide the stored information to an authorized user or the patient, control an implantable device to initiate or adjust a neuromodulation therapy, or adjust sensor operations.
