Abstract:
Techniques for configuring electrical stimulation therapy utilizing one or more stimulation intensity values are described. In one example, a method includes receiving a stimulation intensity value that corresponds to an equal intensity function; determining a pulse width value and a pulse amplitude value based on the equal intensity function; and controlling delivery of electrical stimulation pulses with the determined pulse width value and amplitude value to a patient. A stimulation intensity value may correspond to a plurality of paired pulse width and amplitude values having substantially the same intensity. For example, the plurality of paired pulse width and amplitude values may activate a substantially equal volume of tissue when a stimulation pulse with the paired values is delivered.
Abstract:
This disclosure describes techniques for programming stimulation therapy programs according to therapy targets (e.g., symptoms or areas of pain) in a patient to which they are applied. Several programs can be programmed for each therapy target, stored on an implantable medical device, and retrieved later by a programmer to modify, edit, delete, create, and/or select a therapy program for each of the therapy targets. Each therapy target is independent from the other therapy targets, and a user can select or change a program under one therapy target without affecting programs under the other therapy targets. During programming, a user can specify parameters for each program applicable to only that program, and can specify parameters for each therapy target applicable to every program associated with that therapy target. The organization of programs into slots and the selection of a program in each slot may be manual or automated.
Abstract:
The disclosure is directed to a user interface with a menu that facilitates stimulation therapy programming. The user interface displays a representation of the electrical leads implanted in the patient and at least one menu with icons that the user can use to adjust the stimulation therapy. The user may drag one or more field shapes from a field shape selection menu onto the desired location relative to the electrical leads. A manipulation tool menu may also allow the user to adjust the field shapes placed on the electrical leads, which represent the stimulation region. The programmer that includes the user interface then generates electrical stimulation parameter values for the stimulator to deliver stimulation according to the field shapes or field shape groups defined/located by the user. The field shapes may represent different types of stimulation representations, such as current density, activation functions, and neuron models.
Abstract:
An implantable nerve stimulator is implanted in a patient near a nerve target. The implantable nerve stimulator has a plurality of electrodes through which stimulation is provided to the nerve target. The relative location of the nerve target and the electrodes may be determined by applying stimulation to the nerves via each of the electrodes, determining an effect of the stimulation for each of the electrodes, and mapping a location of the nerve relative to the electrodes based on the effect of the stimulation for each of the electrodes.
Abstract:
An apparatus including a processor configured to selectively load a first operating system that controls general purpose computer functionality of the apparatus; and a second operating system different from the first operating system. The second operating system controls medical device programming functionality of the apparatus, enabling the apparatus to program a medical device including at least one implantable component.
Abstract:
The disclosure is directed to techniques for shifting between two electrode combinations. An amplitude of a first electrode combination is incrementally decreased while an amplitude of a second, or subsequent, electrode combination is concurrently incrementally increased. Alternatively, an amplitude of the first electrode combination is maintained at a target amplitude level while the amplitude of the second electrode combination is incrementally increased. The stimulation pulses of the electrode combinations are delivered to the patient interleaved in time. In this manner, the invention provides for a smooth, gradual shift from a first electrode combination to a second electrode combination, allowing the patient to maintain a continual perception of stimulation. The shifting techniques described herein may be used during programming to shift between different electrode combinations to find an efficacious electrode combination. Additionally, the techniques may be used for shifting between different electrode combinations associated with different stimulation programs or program sets.

Abstract:
Techniques are described, for medical devices that deliver electrical stimulation therapy, for controlling a transition from an initial stimulation location or initial stimulation shape to a user-specified target stimulation location or target stimulation shape in order to limit the rate of change of stimulation. One example method includes receiving, via a programmer for an electrical stimulator, user input indicating a target stimulation zone, and controlling the electrical stimulator to transition electrical stimulation from an initial stimulation zone to the target stimulation zone via one or more intermediate stimulation zones.
Abstract:
This disclosure is related to techniques for presenting therapy factors related to medical device therapy in a manner that allows a user, such as a patient or a clinician, to receive, comprehend and evaluate information relating to therapy delivered by the medical device efficiently. In one aspect, a method comprises obtaining a data set corresponding to a therapy factor associated with delivery of a medical therapy to a patient with a medical system including an implantable medical device, receiving a user selection associated with a subset of the data set, the subset of the data set including less than all the information relating to the therapy factor in the data set, and presenting a representation, corresponding to the subset of the data set, of the therapy factor on a display of a programmer.
