An implantable medical device (IMD) may include a communication module, a therapy control module, a firmware control module, and a service application. The communication module is configured to wirelessly communicate over an RF link with an external device. The therapy control module is configured to deliver therapy to the patient, and may include a reprogrammable therapy logic circuit configured to operate the therapy control module in a reprogrammable mode of operation, and base-therapy state machine (BTSM) logic circuit configured to operate the therapy control module in a base therapy mode of operation. The firmware control module may include CPU and a memory. The service application may be stored in the memory. The firmware control module is configured to launch the service application, and the BTSM logic circuit provides a base level of sensing and pacing therapy while the communications module in parallel maintains the RF link with the external device.

System and method for operating an implantable medical device through radio frequency signals

Systems and methods are provided for maintaining a bi-directional communication link between an external device and an implantable medical device (IMD). The systems and methods receive a connection request from an external device at the IMD. The communication request includes one or more communication link parameters based on a wireless protocol, defining a first communication interval. The systems and methods establish a bi-directional communication link between the external device and the IMD based on the one or more communication link parameters, and receive, during the first communication interval, a data packet from the external device along a first data channel, the data packet including an adjusted communication link parameter. The adjusted communication link parameter include a second communication interval.

Systems and methods for maintaining a bi-directional communication between an implantable medical device and an external device

A system and method are provided for initiating a secured bi-directional communication session with an implantable medical device. The system and method include configuring a pulse generator (PG) device and an external device to establish a communication link there between through a wireless protocol with a defined bonding procedure. The system and method also include transmitting a static identification and dynamic seed from the PG device through a dedicated advertisement channel to the external device and generating a passkey from a pre-defined algorithm based on the dynamic seed and a static identification. Further, the system and method include starting the defined bonding procedure.

System and method for establishing a secured connection between an implantable medical device and an external device

Techniques are provided for use with implantable medical devices or trial medical devices for wirelessly connecting the devices to external instruments such as tablet computers or smartphones. In an example where the medical device is an implantable neurostimulator, the neurostimulator passively detects wireless wake-up signals generated by the external instrument, i.e. the neurostimulator 'sniffs' for advertisement signals generated by the external instrument. In response to passive detection of a wake-up signal, the implantable neurostimulator determines if a response is warranted and, if so, the neurostimulator activates its wireless transmission components to transmit an acknowledgement signal to the external instrument so as to complete a wake-up and handshake protocol. In this manner, power consumption within the implantable device (or within a similarly equipped trial medical device) can be reduced compared to devices that would otherwise periodically transmit advertisement signals even when no external mobile instrument is present.

Systems and methods for low energy wake-up and pairing for use with implantable medical devices

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.
