1. An implantable system, comprising: an implantable lead with a proximal end and a distal end, wherein the distal end is adapted to be implanted for use to deliver neural stimulation pulses to selectively stimulate nerve root targets; an implantable housing, wherein the proximal end of the lead is adapted to connect to the housing; a neural stimulation circuit in the housing, wherein the neural stimulation circuit is adapted to generate neural stimulation pulses for delivery from the distal end of the implanted lead to selectively stimulate the nerve root targets, wherein, when the lead is implanted, the neural stimulation circuit and the implantable lead are configured to only target a ventral nerve root, only target a dorsal nerve root, and target both the ventral nerve root and the dorsal nerve root; and a controller in the housing and connected to the neural stimulation circuit, wherein the controller is adapted to control the neural stimulation circuit to deliver a neural stimulation treatment.
