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.

Claims

1. A method for treating a patient, comprising:

receiving a first input indicating a location of a signal delivery device implanted in a patient, relative to at least one of the patient'"'"'s vertebrae;

establishing a positional relationship between the implanted signal delivery device and the at least one vertebra;

receiving a second input corresponding to a medical indication of the patient;

receiving a third input provided by a user and corresponding to a requested change in axial length of a computer-based image of the at least one vertebra;

accessing a database of patient information correlating signal delivery parameters and medical indications for other patients; and

based at least in part on the positional relationship, the medical indication, and information contained in the database, automatically identifying a signal delivery parameter in accordance with which a pulsed electrical signal is delivered to the patient via the signal delivery device, wherein the signal delivery parameter includes an identity of an electrode to which the pulsed electrical signal is delivered, the electrode being carried by the signal delivery device.

2. The method of claim 1 wherein receiving a first input includes receiving an input provided by a user moving a computer-based image of the lead relative to a computer-based image of the at least one vertebra.

3. The method of claim 1 wherein the patient is one of multiple patients presenting with the medical indication, and wherein the method further comprises updating the database with data from the patient.

4. The method of claim 1 wherein accessing the database includes accessing a correlation between the medical indication and a vertebral level, and wherein automatically identifying a signal delivery parameter includes selecting an electrode carried by the signal delivery device and positioned proximate to the vertebral level.

5. The method of claim 4 wherein the selected electrode is an electrode closest to the vertebral level.

6. The method of claim 1, further comprising delivering the pulsed electrical signal in accordance with the signal delivery parameter.

7. The method of claim 6 wherein delivering the pulsed electrical signal includes delivering the pulsed electrical signal at a frequency in a frequency range of from about 1.5 kHz to about 100 kHz.

8. The method of claim 6 wherein delivering the pulsed electrical signal includes delivering the pulsed electrical signal at a frequency in a frequency range of from about 1.5 kHz to about 50 kHz.

9. The method of claim 6 wherein delivering the pulsed electrical signal includes delivering the pulsed electrical signal at a frequency in a frequency range of from about 3 kHz to about 20 kHz.

10. The method of claim 1 wherein the signal delivery parameter is a first signal delivery parameter and wherein the method further comprises automatically identifying a second signal delivery parameter that includes at least one of a signal frequency, amplitude and pulse width.

11. The method of claim 1, further comprising:

receiving a third input corresponding to a movement of the signal delivery device; and

based at least in part on the third input, automatically updating the signal delivery parameter.

12. The method of claim 1 wherein the signal delivery device is a first signal delivery device, and the positional relationship is a first positional relationship, and wherein the method further comprises:

establishing a second positional relationship between the first signal delivery device and a second delivery device implanted into the patient; and

based at least in part on the second positional relationship, updating the signal delivery parameter for signals delivered from the second signal delivery device.

13. The method of claim 1 wherein the first input is automatically determined from a computer-based image of the signal delivery device.

14. The method of claim 1 wherein the medical indication is selected from a list of medical indications comprising back pain, leg pain, total body pain and headache pain.

15. The method of claim 1 wherein the signal delivery parameter has a first value, and wherein the method further comprises replacing the first value with a second value in response to an event.

16. The method of claim 15 wherein the first value is an identity of a first electrode, the second value is an identity of a second electrode different than the first electrode, and the event is an indication that a circuit that includes the first electrode has an impedance higher or lower than a target value.

17. The method of claim 1 wherein receiving the first input is performed by instructions carried by a computer-readable medium.

18. The method of claim 1 wherein establishing the positional relationship is performed by instructions carried by a computer-readable medium.

19. The method of claim 1 wherein receiving the second input is performed by instructions carried by a computer-readable medium.

20. The method of claim 1 wherein automatically identifying the signal delivery parameter is performed by instructions carried by a computer-readable medium.
