Patent ID: 7123967

Claim:
An implantable neural stimulation device for treating peripheral vascular disease of a patient, the device comprising: a pulse generator that is operative to provide stimulation pulses; an implantable lead that is configured to apply the stimulation pulses to neural tissue; an activity sensor that is operative to sense an activity level of the patient; and a processor that is responsive to the activity sensor to control application of the stimulation pulses by the pulse generator; wherein the processor enables the pulse generator to provide the stimulation pulses when the patient is active; wherein the activity sensor senses activity level of the patient over an extended long term time period to provide an indication of progression and regression of the peripheral vascular disease; wherein the processor determines a degree of stimulation responsive to the indication provided by the activity sensor of the progression and regression of the peripheral vascular disease; and wherein the processor enables the pulse generator to increase the degree of neural stimulation pulses when a long term activity average decreases.
