Abstract: Devices, systems, and techniques are described for adjusting therapy parameters defining electrical stimulation therapy delivered by multiple electrodes while maintaining a ratio of a value of a therapy parameter between the multiple electrodes. In one example, a device defines a relationship for multiple electrodes that defines a ratio of a value of a therapy parameter between the multiple electrodes. The device performs a master adjustment that adjusts each value of the therapy parameter for each respective electrode of the multiple electrodes by an amount specified by the relationship to maintain the ratio of the value of the therapy parameter between the multiple electrodes. The device controls delivery of electrical stimulation therapy according to the master adjustment.

Abstract: Techniques are described, for medical devices that deliver electrical stimulation using current or voltage regulators having an adjustable master amplitude. One example method includes receiving, via a programmer for an electrical stimulator, user input indicating a desired electrical current amplitude, and selecting a first fraction adjustment or a second fraction adjustment, as a target adjustment for achieving the desired electrical current amplitude.

Abstract: An example system includes a lead including a first electrode disposed at a first level, a second electrode disposed at a second level, a first group of segmented electrodes disposed at a third level, and a second group of segmented electrodes disposed at a fourth level. The example system also includes a medical device configured to deliver symmetrical electrical stimulation to a patient via the first group of segmented electrodes and the second group of segmented electrodes and sense a response to the stimulation via the first electrode and the second electrode.

Abstract: Techniques are described for displaying a representation of a supplemental bolus and a representation of programmed doses of a therapy schedule for an implantable fluid delivery device with a programmer device. In one example, a device includes a user interface to present a graphical representation of doses of fluid to be delivered to a patient via an implantable fluid delivery device and a processor that controls the user interface to simultaneously present a first graphical representation of a supplemental bolus to be delivered by the implantable fluid delivery device and a second graphical representation of programmed doses of a therapy schedule of the implantable fluid delivery device, wherein at least a portion of the programmed doses of the therapy schedule follows delivery of the supplemental bolus by the implantable fluid delivery device. A user of the device may determine whether the representations indicate an excessive dosage risk to the patient.

Abstract: A telemetry interface module according to the invention may be utilized to facilitate remote programming of a patient medical device such as an implantable medical device. The telemetry interface module includes processing logic, memory, and various software/firmware applications that are capable of generating a user interface (“UI”) description for transmission to a remote computing device. The UI description is transmitted in accordance with a standardized data communication protocol, and the remote computing device renders a UI in response to the received UI description. The remote computing device processes and renders the UI using its native operating system and native UI controls, thus eliminating the need for computing hardware customized for the particular medical device telemetry application.
