  • Patent number: 12133985
    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.

  • Publication number: 20240307689
    Abstract: An example system includes electrical stimulation circuitry configured to generate electrical stimulation, electrodes configured to deliver the electrical stimulation to a patient, and processing circuitry configured to determine, for a patient, a first cycling of electric stimulation doses. The processing circuitry is also configured to deliver the electric stimulation doses according the determined first cycling, receive patient feedback representing a response of the patient to the electric stimulation doses delivered according to the first cycling, determine, based on the patient feedback, a second cycling of the electric stimulation doses, and deliver the electric stimulation doses to the patient according the determined second cycling. Delivering the electric stimulation doses for the patient according to the determined second cycling consumes less power of the implanted device than delivering the electric stimulation doses for the patient according to the determined first cycling.

  • Patent number: 12036401
    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).

  • Publication number: 20240181264
    Abstract: An external device transfers a key to an implantable medical device over a proximity communication and then establishes a first far field communication session with the implantable medical device where the key is used for the first communication session. This first communication session may occur before implantation while the implantable medical device is positioned outside of the sterile field so that using a proximity communication is easily achieved. Once the implantable medical device is passed into the sterile field for implantation, the external device may then establish a second far field communication session with the implantable medical device where the last key that was used for the first communication session is again used for the second communication session which avoids the need for another proximity communication to occur within the sterile field.

  • Publication number: 20240123233
    Abstract: An example system includes electrodes configured to deliver the electrical stimulation to a patient, and a device comprising processing circuitry configured to determine, for a patient, a loading dose of electric stimulation. The processing circuitry is also configured to cause electrical stimulation circuitry' to deliver, during a first time period, the loading dose to the patient, receive patient feedback representing a response of the patient to the loading dose, determine, based on patient feedback, a maintenance dose of electrical stimulation, and cause the electrical stimulation circuitry to deliver, and during a second time period that is after the first time period, a maintenance dose of electrical stimulation. Delivering the maintenance dose of electrical stimulation consumes less power than delivering the loading dose of electrical stimulation.

  • Patent number: 11458303
    Abstract: Implantable medical systems include implantable percutaneous medical leads and/or implantable medical lead extensions that have fewer conductors than distal electrodes, or distal connectors for extensions, by having one or more conductors be electrically coupled to multiple distal electrodes. The multiple distal electrodes may span a general area of a body of a patient that includes a specific point that requires therapy, such as multiple vertebral segments. Because all distal electrodes spanning the general area that are coupled to an active conductor will output the stimulation therapy, the specific point within the general area will receive the therapy even without identifying which electrode is most effective. Bipolar and unipolar stimulation modes may be used. Multiple leads may be used where each lead has more distal electrodes than conductors. Additionally, a single lead may have more distal electrodes than conductors while also carrying multiple stimulation waveforms.
