Clinician programmer system and method for steering volumes of activation

摘要

A system and method for selection of stimulation parameters for Deep Brain Stimulation (DBS) may include a processor that displays in a display device and in relation to a displayed model of a leadwire including model electrodes, a current field corresponding to a first stimulation parameter set, provides a user interface for receipt of user input representing a shift of the current field, in response to the user input, moves, in the display device, the current field with respect to the displayed model, determines a second stimulation parameter set that results in the moved current field, and outputs the second stimulation parameter set and/or sets a stimulation device with the second stimulation parameter set, where the stimulation device is configured for performing a stimulation using the leadwire in accordance with the second stimulation parameter set.

主权项

1. A method of a stimulation parameter selection machine, the method comprising:
displaying, by a processor of the machine, via a display device, and in relation to a displayed model of a leadwire, an initial current field corresponding to a first stimulation parameter set; in response to user input, shifting, by the processor, the display of the current field with respect to the displayed leadwire model; determining, by the processor, a second stimulation parameter set that results in the shifted current field; and at least one of (a) outputting the second stimulation parameter set, and (b) setting a stimulation device with the second stimulation parameter set, the stimulation device configured for performing a stimulation (1) using a leadwire modeled by the leadwire model and (2) in accordance with the second stimulation parameter set; wherein:
the user input is via hitting one or more displayed components of a user interface;the displayed components include a first set of directional buttons that each corresponds to a respective axial direction and for each of which the processor is configured to interpret hitting of the respective button as an instruction to shift the displayed current field in the respective axial direction to which the respective directional button corresponds; andat least one of:
the displayed components further include a rotational directional button, hitting of which the processor is configured to interpret as an instruction for a gradual shift of the displayed current field rotationally about a central axis; andthe first set of directional buttons includes a button, a hit of which the processor is configured to interpret as an instruction to shift the displayed current field from a first location to a second location that mirrors the first location about a predetermined axis.
