Abstract: A method includes receiving, with one or more processors, a first ambulatory velocity information of a patient while electrical stimulation with a first set of stimulation parameters is being delivered to the patient; adjusting, based on the first ambulatory velocity information and by a predetermined amount, one or more of the first set of stimulation parameters to generate an adjusted set of stimulation parameters by a predetermined amount; receiving, with the one or more processors, a subsequent ambulatory velocity information of the patient while the electrical stimulation with an adjusted set of stimulation parameters is being delivered to the patient; and generating, with the one or more processors and based on the subsequent ambulatory velocity, one or more recommended electrical stimulation parameters the patient.

Abstract: Devices, systems, and techniques are described for adjusting therapy parameters defining electrical stimulation therapy. An example system includes a stimulation generator comprising a voltage stack configured to provide a stack voltage based on a multiplier of a battery voltage and processing circuitry. The processing circuitry receives a first set of parameter values that use a first stack voltage of the voltage stack to provide a first electrical stimulation defining a first therapy. The processing circuitry also determines, based on a second stack voltage lower than the first stack voltage, a second set of parameter values that define a second electrical stimulation, the second set of parameters defining a lower amplitude of electrical stimulation. Additionally, the processing circuitry controls the stimulation generator to deliver the second electrical stimulation according to the second set of parameter values using the second stack voltage of the voltage stack.

Abstract: Techniques for therapy delivery are described. A processing circuit may adjust a first therapy parameter from a first level to a second level, and responsive to the adjustment of the first therapy parameter, compare a level of an evoked compound action potential (ECAP) generated from therapy delivery based on the adjusted first therapy parameter to an ECAP threshold. The processing circuit may adjust a second therapy parameter from a third level to a fourth level based on the comparison. The second therapy parameter is different than the first therapy parameter. The processing circuit may cause therapy delivery with the first therapy parameter at the second level and the second therapy parameter at the fourth level.

Abstract: Far field telemetry communications are conducted during recharge sessions between an external device and an implantable medical device. The two devices may not have been previously paired together for far field telemetry and may have been paired with other devices for far field telemetry during previous recharge sessions and/or programming sessions. Embodiments provide for temporary bonding of the two devices for far field telemetry during the recharge session. The implantable medical device of the recharge session may maintain a programming bond with an external device other than the external device conducting the recharge session. Safeguards against establishment of inadvertent programming sessions between the external device that has conducted a recharge session and implantable medical devices that may or may not be bonded to that external device are provided.

Abstract: In some examples, a medical device is configured to automatically determine a paresthesia threshold or a perception threshold of a patient in a second posture based on the paresthesia threshold or perception threshold of that patient in a first posture. The medical device may deliver an electrical stimulation signal to a patient and determine the paresthesia threshold or perception threshold for the patient in the first posture. The medical device may change the intensity of the electrical signal and receive an indication from the patient that they are experiencing paresthesia or perceiving the electrical stimulation signal. The medical device may then automatically determine a predicted paresthesia threshold or predicted perception threshold for a second posture based on the paresthesia threshold or perception threshold.

Abstract: In some examples, a medical device is configured to deliver sub-threshold electrical stimulation therapy to a patient at a stimulation intensity that is significantly less than a perception or paresthesia threshold intensity level for the patient. The medical device may determine the particular intensity level for the patient through a titration process. The medical device may titrate automatically or based upon the input of the patient, a clinician or a physician.

Abstract: A medical system implements a seizure detection algorithm to detect a seizure based on a first patient parameter. The medical system monitors a second patient parameter to adjust the seizure detection algorithm. In some examples, the medical system determines whether a seizure for which therapy delivery is desirable occurred based on a second patient parameter. If a target seizure occurred, and the seizure detection algorithm did not detect the target seizure, the medical system adjusts the seizure detection algorithm to detect the target seizure. For example, the medical system may determine a first patient parameter characteristic indicative of the target seizure detected based on the second patient parameter and store the first patient parameter characteristic as part of the seizure detection algorithm. In some examples, the first patient parameter is an electrical brain signal and the second patient parameter is patient activity (e.g., patient motion or posture).

Abstract: Techniques for delivery of electrical neurostimulation therapy to a patient are disclosed. In one example, a processor controls delivery of electrical neurostimulation therapy to a patient by an electrical neurostimulation therapy device and via a plurality of combinations of a plurality of electrodes disposed along a lead inserted across an anatomical midline of a spinal cord of the patient and angled relative to the anatomical midline, the lead connected to the electrical neurostimulation therapy device. The processor determines, based on the electrical neurostimulation therapy, a location of a physiological midline of the spinal cord. The processor selects, based on the location of the physiological midline, at least one electrode of the plurality of electrodes for subsequent delivery of electrical neurostimulation therapy to the patient. Further, the processor displays a representation of the physiological midline and the anatomical midline relative to the spinal cord.
