  • Patent number: 10159843
    Abstract: A first fraction of an electrical stimulation is allocated to a first electrode. In response to user input, the first fraction of the electrical stimulation is fixed to the first electrode such that the first fraction is user-adjustable but cannot be automatically changed. In response to the first fraction being fixed to the first electrode, a respective second fraction of the electrical stimulation is automatically allocated to a plurality of second electrodes. The second fraction is a function of the first fraction and a total number of the second electrodes. Thereafter, a new electrode is added to, or deleting from, the second electrodes, while the first fraction is still fixed to the first electrode. The respective second fractions are automatically adjusted in response to the adding or the deleting, without affecting the first fraction of the electrical stimulation that has been fixed to the first electrode.

  • Patent number: 10080903
    Abstract: Method and systems for optimizing acoustic energy transmission in implantable devices are disclosed. Transducer elements transmit acoustic locator signals towards a receiver assembly, and the receiver responds with a location signal. The location signal can reveal information related to the location of the receiver and the efficiency of the transmitted acoustic beam received by the receiver. This information enables the transmitter to target the receiver and optimize the acoustic energy transfer between the transmitter and the receiver. The energy can be used for therapeutic purposes, for example, stimulating tissue or for diagnostic purposes.

  • Patent number: 9996669
    Abstract: Techniques for automatically identifying medical devices, e.g., implantable medical device, using wireless communications in order to communicate with the medical devices are described. For instance, a programming system securely discovers a set of medical devices which have the capacity to communicate using wireless communication links. The programming system may then apply one or more search heuristics to identify a set of discovered medical devices that are likely to be a medical device with which a user desires to interact. When the user selects the desired one of the identified medical devices, the programming system launches a device interaction application associated with the desired medical device. The user may use the device interaction application to interact with the desired medical device.
