NEUROSTIMULATION THERAPY MANIPULATION
First Claim
1. A method comprising:
- storing an electrode combination map that maps an output of a control device to a predetermined subset of electrode combinations available from a set of electrodes implanted within a patient, wherein the electrode combinations specify polarities of electrodes of the set of electrodes;
receiving the output from the control device, wherein the output reflects manipulation of a directional controller of the control device by a user;
selecting one of the predetermined subset of electrode combinations based on the received output and the electrode combination map; and
controlling a stimulation device coupled to the set of electrodes to apply electrical stimulation to the patient via the selected electrode combination.

Abstract
A user, such as a clinician or the patient, uses a control device to manipulate at least one neurostimulation parameter. A mapping system uses a calibrated map to map the directional output of the control device to values of at least one stimulation parameter to allow the user to intuitively control the value of the parameter. In some embodiments, where a stimulation device is used to deliver spinal cord stimulation (SCS) therapy for example, the user manipulates a parameter to effect the location and/or strength of paresthesia experienced by the patient. In exemplary embodiments, the parameter values are combinations of electrodes, and the mapping system selects electrode combinations based on the output of the control device such that a direction of movement of paresthesia experienced by the patient corresponds to a direction of manipulation of a directional controller of the control device. The mapping system may calibrate the map based on patient paresthesia information received from a user.
