Abstract

An apparatus and method for displaying and controlling parameters for a programmable living tissue stimulator system. Visual indicators corresponding to control parameters or signals for the tissue stimulator system are divided into a predetermined number of groups. One of these groups containing a parameter to be selected for the tissue stimulator system is selected, the selected group being identified by a visually identifiable indication. A parameter within that group is then selected for transmission to an implanted memory means which controls an implanted tissue stimulator. In a specific embodiment, a matrix of visual indicators consisting of R rows and S columns is provided, each visual indicator corresponding to a specific control signal. A means is provided whereby at least one visual indicator contained in a selected R row will blink on and off, the blinking indicators identifying control signals to be selected for the implanted memory means. Selection of a control signal within the selected R row causes the blinking to cease and the visual indicator corresponding to the selected signal to turn on when the selected signal is stored within the implanted memory means. Visual indicators corresponding to the unselected control signals in the selected R row turn off after a signal selection is made.

Claims

1. In combination with a programmable living tissue stimulator system having an implanted stimulating signal generator, an implanted programmable memory means for storing control signals for said implanted signal generator, external programming means for generating control signals in accordance with predetermined input signals, means for transmitting control signals to said implanted memory menas, means for generating verification signals that indicate said transmitted control signals have been received by said implanted memory means, a display and control system comprising:

a plurality of visual indicators each corresponding to a control signal, said visual indicators being divided into R groups of visual indicators;

first means for selecting one of said R groups of visual indicators;

means for causing a first visually identifiable indication to be provided by said selected R group of visual indicators;

second means for selecting a control signal corresponding to one of said visual indicators in said selected R group of visual indicators, said first and second means for selecting defining said predetermined input signals to said external programming means for generating said selected control signal;

means for causing a second visually identifiable indication to be provided by said visual indicators corresponding to unselected control signals in said selected R group of visual indicators; and

means for causing a third visually identifiable indication to be provided by said visual indicator corresponding to said selected control signal when a verification signal corresponding to said selected control signal is generated.

2. The display and control system of claim 1 in which said first means for selecting comprises a first plurality of switches each corresponding to one of said R groups of visual indicators and said second means for selecting comprises a second plurality of switches each corresponding to an order of a visual indicator within an R group of visual indicators.

3. The display and control system of claim 2 in which said means for causing a first visually identifiable indication comprises means for causing said at least one visual indicator to blink on and off, said means for causing a second visually identifiable indication comprises means for causing said visual indicators corresponding to unselected control signals to be off, and said means for causing a third visually identifiable indication comprises means for causing said visual indicator corresponding to said selected control signal to be on.

4. The display and control system of claim 1 in which said visual indicators comprise LCD'"'"'s.

5. The display and control system of claim 1 in which said visual indicators comprise light emitting diodes (LED'"'"'s).

6. The display and control system of claim 1 in which said visual indicators comprise color-coded indicators having one color in the presence of an excitation signal and another color in the absence of an excitation signal.

7. The display and control system of claim 1 in which said external programming means comprises means for determining control signals stored in said implanted memory means in response to an interrogate signal and means for providing verification signals corresponding to said stored control signals, said display and control system further comprising:

switch means for providing said interrogate signal to said external programming means; and

means responsive to said verification signals for causing visual indicators corresponding to control signals stored in said memory means to provide said third visually identifiable indication.

8. The display and control system of claim 1 in which said external programming means comprises means for generating a reprogram signal when a verification signal corresponding to said selected control signal is not generated, said display and control system further comprising visual display means for indicating presence of said reprogram signal.

9. The display and control system of claim 1 in which said external programming means comprises means for generating a position head signal when said transmitting means is not within a predetermined distance from said implanted stimulating signal generator, said display and control system further comprising visual display means for indicating presence of said position head signal.

10. A display and control system for a programmable living tissue stimulator system comprising:

a plurality of visual indicators located in a matrix having R rows and S columns, each visual indicator corresponding to a control signal for said tissue stimulator system;

first means for selecting one of said R rows of visual indicators;

means for visually indicating said selected R row;

second means for selecting one of said S columns;

means for providing an output to said tissue stimulator system corresponding to a control signal defined by said selected R row and said selected S column; and

means for displaying a verification signal from said tissue stimulator system corresponding to said control parameter defined by said selected R row and said selected S column.

11. The display and control system of claim 10 in in which said first means for selecting comprises a plurality of row selection switches each corresponding to one of said R rows and said second means for selecting comprises a plurality of column selection switches each corresponding to one of said S columns.

12. The display and control system of claim 10 in which said means for visually indicating said selected R row comprises means for causing said visual indicators comprising said selected R row to provide a first visually identifiable indication.

13. The display and control system of claim 12 further comprising means for causing said visual indicators in said selected R row but not in said selected S column to provide a second visually identifiable indication.

14. The display and control system of claim 13 in which said means for displaying a verification signal from said stimulator system comprises means for causing said visual indicator corresponding to said verification signal control signal to provide a third visually identifiable indication.

15. The display and control system of claim 14 in which said visual indicators are LCD'"'"'s, and said first visually identifiable indication is an alternating "on-off" indication, said second visually identifiable indication is an "off" indication, and said third visually identifiable indication is an "on" indication.

16. The display and control system of claim 10 further comprising:

means for providing an interrogate signal to said tissue stimulation system; and

means for causing said visual indicators to provide visually identifiable indications responsive to verification signals provided by said tissue stimulator system as a result of said interrogate signal.

17. The display and control system of claim 10 further comprising means for displaying a position head signal provided by said stimulator system.

18. A method for displaying and controlling parameters for a programmable living tissue stimulation system, the steps comprising:

locating a plurality of visual indicators in a matrix having R rows and S columns, each visual indicator corresponding to a control signal for said stimulator system;

selecting one of said R rows;

visually indicating said selected R row;

selecting on of said S columns;

providing an output to said tissue stimulator system corresponding to a control signal defined by said selected R row and said selected S column; and
