Patent ID: 8768452

Claim:
An implantable neurostimulator comprising: a neurostimulation generator; a processor that controls the neurostimulation generator to generate neurostimulation in a trial mode as a first operating mode upon initial implantation of the neurostimulator and before generation of electrical stimulation in any chronic mode by the neurostimulation generator, to evaluate efficacy of the neurostimulator; and one or more sensors that sense one or more parameters related to a patient during the trial mode, wherein the processor controls the neurostimulation generator to generate neurostimulation in the chronic mode after completion of the trial mode and only if the trial mode indicates that the neurostimulator provides efficacious therapy to the patient, wherein the processor controls the neurostimulation generator to generate neurostimulation in the chronic mode according to a set of electrical stimulation parameter values that is different than any sets of electrical stimulation parameter values that define neurostimulation generated during the trial mode.
