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 structure, each node defines respective values for a set of electrical stimulation parameters, the nodes in each level specify an adjustment to a value of at least one type of stimulation parameter, and the nodes in different levels specify adjustments to the value of different types of stimulation parameters;
defining a program path through the tree structure along a series of the interconnected nodes for which performance feedback regarding stimulation therapy delivered according to the stimulation parameters defined by the nodes exceeds a threshold level, wherein the performance feedback comprises system performance feedback indicative of power consumption of a medical device that delivers the stimulation therapy according to the stimulation parameters defined by the selected node;
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 to treat a patient.

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 program path is created 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. Performance feedback may be used by the system to evaluate nodes of the therapeutic tree and define the program path. The performance feedback may include beneficial effects, adverse effects, and system performance related to the stimulation therapy. Additionally, one or more sensors may provide the performance feedback.
