  • Publication number: 20170050034
    Abstract: A first fraction of an electrical stimulation is allocated to a first electrode. In response to user input, the first fraction of the electrical stimulation is fixed to the first electrode such that the first fraction is user-adjustable but cannot be automatically changed. In response to the first fraction being fixed to the first electrode, a respective second fraction of the electrical stimulation is automatically allocated to a plurality of second electrodes. The second fraction is a function of the first fraction and a total number of the second electrodes. Thereafter, a new electrode is added to, or deleting from, the second electrodes, while the first fraction is still fixed to the first electrode. The respective second fractions are automatically adjusted in response to the adding or the deleting, without affecting the first fraction of the electrical stimulation that has been fixed to the first electrode.

  • Publication number: 20160361542
    Abstract: A non-zero starting value for ramping up a stimulation parameter for an electrical stimulation to be delivered to a patient is determined. The non-zero starting value is customized to the patient. A pulse generator is caused to generate the electrical stimulation, which is delivered to the patient via an implanted lead. The pulse generator is caused to ramp up, from the determined non-zero starting value and toward a predefined maximum limit value, the stimulation parameter for a plurality of electrode contacts on the lead. Feedback is received from the patient in response to the ramping up. The feedback is received via an electronic patient feedback device. Based on the ramping up and the received feedback from the patient, a perception threshold is determined for each of the plurality of electrode contacts. The perception threshold is a value of the stimulation parameter that corresponds to the patient feeling the electrical stimulation.
