Abstract: An advertising algorithm is disclosed which operates in an Implantable Medical Device (IMD) to adjust an interval at which the IMD will transmit advertising data packets to an external device able to connect with the IMD. When a communication session between the IMD and an external device is terminated, the advertising algorithm will issue advertising data packets at a higher rate for a set duration. This will allow the external device to connect more quickly with the IMD in a next communication session. After the set duration, when it may be assumed that the external device is less likely to connect with the IMD, the algorithm reduces that rate at which advertising data packets are issued, which saves power in the IMD.

Abstract: Systems and methods are disclosed for use with Implantable Medical Devices (IMD) such as Implantable Stimulator Devices. The system includes a permanent magnet which can be used to reset the IMD (such as during an emergency) and to place the IMD in a pairing mode to establish communications with an external device. An external device paired to the IMD can be used to place the IMD in an MRI mode that renders the IMD safe during a Magnetic Resonance Imaging (MRI) scan. In the event that the external device is unavailable to cause the IMD to exit the MRI mode, the bar magnet can also be used in the MRI mode to pair the IMD with another external device.

Abstract: Techniques for determining baseline voltages to assess sensed neural responses or other sensed signals in an implantable stimulator device are disclosed, which allows features of the neural responses or other signals to be more easily and reliably established. Features of the neural response, indicative of the AC characteristics of the responses, may be used to control or monitoring stimulation in the device, and certain features may vary with a DC offset voltage in the tissue. The determined baseline voltages compensate for such DC offset voltages, and therefore allow certain AC features of the neural response to be determined more accurately and meaningfully.

Abstract: A system may include a user device, a clinician programmer and an implantable medical device. A first security protocol may be used to establish a first encrypted communication channel between the clinician programmer and the user device through cloud server(s). The first security protocol may authenticate entities and establish a first key set for encrypting and decrypting messages transmitted within the first encrypted communication channel. The user device and the implantable medical device may be configured to wirelessly communicate with each other through a secure wireless connection. A second security protocol may be used to establish a second encrypted communication channel, by establishing at least a first secret key, at least partially within the first encrypted communication channel. The second encrypted communication channel may extend between the implantable medical device and the clinician programmer. The first encrypted messages wrap the second encrypted messages.

Abstract: A system may include a stimulator, sensing circuitry and a controller. The stimulator may be operably connected to at least one stimulation electrode, and configured to deliver an electrical waveform for an electrical therapy using the at least one stimulation electrode. The sensing circuitry may be operably connected to at least one sensing electrode, and configured to sense electrical potentials that are evoked by the electrical waveform to provide sensed evoked signals. The controller may be operably connected to the stimulator and the sensing circuitry. The controller may be configured to automatically define a sampling window, sample the sensed evoked potentials during the sampling window to provide sampled values, detect at least one feature from the sampled values, and automatically provide feedback for closed-loop control of the electrical therapy based on the at least one feature.
