Implantable neural stimulation device providing activity, rest, and long term closed-loop peripheral vascular disease therapy and method
First Claim
1. 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.

Abstract
An implantable neural stimulation device and method treats peripheral vascular disease of a patient. The device includes a pulse generator that provides stimulation pulses and an implantable lead that applies the stimulation pulses to neural tissue. An activity sensor senses activity level of the patient and a processor, responsive to the activity sensor, controls the provision of the stimulation pulses by the pulse generator. The processor causes the pulse generator to provide stimulation therapy any time the patient is active or when the patient is at rest. The processor further provides long term activity monitoring and closed loop control of neural tissue stimulation levels to adapt the stimulation therapy to changes in the patient'"'"'s condition.
