Tree-based electrical stimulator programming
First Claim
1. A method for providing electrical stimulation therapy, the method comprising:
- defining a tree structure having a plurality of levels and a plurality of nodes in each of the levels, wherein each of the nodes is interconnected with at least one node above and at least two nodes below in the tree, each node defines a set of electrical stimulation parameters, the nodes in each level specify an adjustment to at least one of the parameters, and the node in different levels specify the adjustment to different parameters;
defining a program path through the tree along a series of the interconnected nodes for which efficacy of stimulation therapy delivered according to the stimulation parameters defined by the nodes exceeds a threshold level;
selecting one of the nodes in the program path; and
delivering the stimulation therapy to a patient based on the parameters defined by the selected node.

Abstract
The disclosure describes an implantable stimulation system that guides programming with a therapeutic tree. All possible stimulation parameters are arranged on the therapeutic tree, with each level of the therapeutic tree containing a different stimulation parameter type. Each level includes nodes that are connected to nodes of adjacent levels. A user, such as a clinician or a patient, creates a program path by moving through nodes of lower levels. The stimulation parameter types are arranged so that coarse adjustments occur at higher levels of the tree and fine adjustments occur at lower levels of the tree. The nodes of the program path define the stimulation parameters of the delivered stimulation therapy. In addition, a sensor may detect a physiological function to allow the system to automatically identify therapy efficacy and create the most efficacious program path for the patient.
