Abstract

Devices for controlling spinal cord modulation for inhibiting pain, and associated systems and methods, including controllers for automated parameter selection are disclosed. A particular embodiment includes receiving a first input corresponding to a location of a signal delivery device implanted in a patient, establishing a positional relationship between the signal delivery device and an anatomical feature of the patient, receiving a second input corresponding to a medical indication of the patient, and, based at least in part on the positional relationship and the indication, automatically identifying a signal delivery parameter in accordance with which a pulsed electrical signal is delivered to the patient via the signal delivery device.

First claim

I claim:

1. A patient treatment system, comprising:
a computer-readable medium having instructions that when executed:
receive a first input corresponding to a location of a signal delivery device implanted in a patient;
establish a positional relationship between the implanted signal delivery device and an anatomical feature of the patient, wherein the anatomical feature includes a vertebra of the patient;
receive a second input corresponding to a medical indication of the patient;
receive a third input provided by a user and corresponding to a requested change in axial length of a computer-based image of the vertebra; and
based at least in part on the positional relationship and the indication, automatically identify a signal delivery parameter in accordance with which a pulsed electrical signal is delivered to the patient via the signal delivery device.

2. The system of claim 1 wherein the instructions, when executed:
receive a fourth input corresponding to an updated location of the signal delivery device; and
in response to the fourth input, automatically update the signal delivery parameter.

3. The system of claim 2 wherein identifying the signal delivery parameter includes identifying a first electrode, and wherein updating the signal delivery parameter includes identifying a second electrode different than the first electrode.

4. The system of claim 1 wherein the third input corresponds to a requested adjustment of a dimension of the vertebra relative to a dimension of the signal delivery device, and wherein the computer-readable medium has intructions that, when executed adjust computer-based data identifying the dimension, in response to the third input.

5. The system of claim 4 , further comprising presenting a graphical representation of the vertebra and the signal delivery device at a computer-based display.

6. The system of claim 1 wherein establishing a positional relationship includes establishing a positional relationship between an electrode of the signal delivery device and the vertebra.

7. The system of claim 1 wherein the computer-readable medium has instructions that when executed:
access a database of patient information correlating signal delivery parameters and medical indications for other patients and wherein
automatically identifying the signal delivery parameter is based at least in part on the information contained in the database.

8. The system of claim 7 wherein the patient is one of multiple patients presenting with the medical indication, and wherein the computer-readable medium has instructions that when executed update the database with data from the patient.

9. The system of claim 7 wherein the instructions for accessing the database include instructions for accessing a correlation between the medical indication and a vertebral level, and wherein the instructions for automatically identifying a signal delivery parameter include instructions for selecting an electrode carried by the signal delivery device and positioned proximate to the vertebral level.

10. The system of claim 9 wherein the selected electrode is the electrode closest to the vertebral level.

11. A patient treatment system, comprising:
a computer-readable medium having instructions that when executed:
present a computer-based image of an implanted signal delivery device and a vertebra of a patient;
receive an input provided by a user and corresponding to a requested change in axial length of the computer-based image of the vertebra; and
update the computer-based image of the vertebra to reflect the requested change.

12. The system of claim 11 wherein the input is a first input and wherein the computer-readable medium further includes instructions that, when executed:
receive a second input corresponding to a medical indication of the patient; and
based at least in part on the indication and a positional relationship between the signal delivery device and the vertebra, automatically identify a signal delivery parameter in accordance with which a pulsed electrical signal is delivered to the patient via the signal delivery device.

13. The system of claim 12 wherein the signal delivery device includes multiple electrodes and wherein the identifying the signal delivery parameter includes identifying which of the electrodes receives the pulsed electrical signal.

14. The system of claim 11 wherein the computer-readable medium has instructions that when executed deliver a pulsed electrical signal to the patient.

15. The system of claim 14 wherein the pulsed electrical signal has a frequency in a frequency range of from about 1.5 kHz to about 100 kHz.

16. The system of claim 14 wherein the pulsed electrical signal has a frequency in a frequency range of from about 1.5 kHz to about 50 kHz.

17. The system of claim 14 wherein the pulsed electrical signal has a frequency in a frequency range of from about 3 kHz to about 20 kHz.

18. A patient treatment system, comprising:
a computer-readable medium having instructions that, when executed:
present a computer-based image of an implanted signal delivery device and an anatomical feature of the patient, wherein the anatomical feature includes at least one of a vertebra and a disk of a patient;
receive an input provided by a user and corresponding to a requested change in axial length of the computer-based image of the anatomical feature; and
update the computer-based image of the anatomical feature to reflect the requested change.

19. The system of claim 18 wherein the input is a first input and wherein the computer-readable medium further includes instructions that, when executed:
receive a second input corresponding to a medical indication of the patient; and
based at least in part on the indication and a positional relationship between the signal delivery device and the anatomical feature, automatically identify a signal delivery parameter in accordance with which a pulsed electrical signal is delivered to the patient via the signal delivery device.

20. The system of claim 19 wherein the signal delilvery device includes multiple electrodes and wherein identifying the signal delivery parameter includes identifying which of the electrodes receives the pulsed electrical signal.

21. The system of claim 18 wherein the computer-readable medium has instructions that, when executed, deliver a pulsed electrical signal to the patient.

22. The system of claim 21 wherein the pulsed electrical signal has a frequency in a frequency range of from about 1.5 kHz to about 100 kHz.

23. The system of claim 21 wherein the pulsed electrical signal has a frequency in a frequency range of from about 1.5 kHz to about 50 kHz.

24. The system of claim 21 wherein the pulsed electrical signal has a frequency in a frequency range of from about 3 kHz to about 20 kHz.
