System and method for shaped phased current delivery

A method implemented using one or more electrodes adjacent spinal column tissue, an implantable device, and an external device, the method comprising:

• treating an ailment suffered by a patient, including:
• using the external device to receive a user selection of a waveform shape type that has a first phase and a second phase;
• using the external device to receive a user input and respond to the received user input by independently adjusting one of the first phase or the second phase of the user-selected waveform shape type without adjusting the other of the first phase or second phase to provide a user-adjusted waveform;
• and
• using the implantable device to deliver electrical modulation energy from the one or more electrodes to the spinal column tissue in accordance with the user-adjusted waveform.

A system for treating an ailment suffered by a patient, the system comprising:

• one or more electrical terminals configured for being coupled to one or more modulation leads;
• a user interface configured to receive user input including receive a user selection of a waveform shape type that has a first phase and a second phase and receive a user input to independently adjust one of the first phase or the second phase;
• control circuitry configured to receive the user input from the user interface and to respond to the received user input by independently adjusting one of the first phase or the second phase of the user-selected waveform shape type without adjusting the other of the first phase or second phase to provide a user-adjusted waveform;
• and
• output modulation circuitry configured to deliver electrical modulation energy from the one or more electrodes to the spinal column tissue in accordance with the user-adjusted waveform.
