1. A system for stimulating a selected nerve target, the system comprising:
- two or more neural stimulation leads;
an array of electrodes disposed, at least in part, on the two or more neural stimulation leads and adapted to be implantably positioned adjacent a single peripheral nerve trunk, the array of electrodes including at least a first electrode disposed on a first neural stimulation lead and a second electrode disposed on a second neural stimulation lead;
an implantable medical device including a programmable memory adapted to receive a programming signal, at least partially based on a physiologic signal generated by a physiologic sensor and indicative of a status of one or more physiologic parameters, for selectively applying electrical stimulation to a stimulation electrode vector combination of at least two electrodes within the electrode array; and
wherein the two or more neural stimulation leads include or are attached to a positioning feature configured for allowing the leads to be implantably positioned adjacent to the single peripheral nerve trunk.

Abstract
Systems and methods for steering one or more stimulation fields to a selected nerve target, thereby optimizing one or a combination of low stimulation thresholds, desired therapy outcomes, or a minimization of adverse stimulation side-effects. An array of electrodes disposed, at least in part, on two or more neural stimulation leads are used for steering the stimulation fields to the selected nerve target and are positioned adjacent the selected target. The stimulation may be titrated based on, among other things, a detected physiologic response to the applied stimulation.
