Abstract

A method of performing a medical procedure, such as surgery, is provided. The spinal cord is stimulated in order to control at least one physiological function. The medical procedure is performed and stimulation of the spinal cord is stopped.

Claims

1. A method of performing a medical procedure, comprising:

stimulating a spinal cord to control at least one physiological function;

performing the medical procedure; and

stopping stimulation of the spinal cord, wherein the physiological function is a function of the lungs.

2. The method of performing a medical procedure, comprising:

stimulating a spinal cord to control at least one physiological function;

performing the medical procedure; and

stopping stimulation of the spinal cord, wherein the physiological function is a function of the heart.

3. A method of performing a medical procedure, comprising:

stimulating a spinal cord to control at least one physiological function;

performing the medical procedure; and

stopping stimulation of the spinal cord, wherein the spinal cord is stimulated intermittently.

4. A method of performing a medical procedure, comprising:

stimulating a spinal cord to control at least one physiological function;

performing the medical procedure; and

stopping stimulation of the spinal cord,

further comprising;

delivering at least one drug during the medical procedure.

5. The method of claim 4 wherein the drug is selected from the group consisting of:

a beta-blocker, a cholinergic agent, a cholinesterase inhibitor, a calcium channel blocker, a sodium channel blocker, a potassium channel agent, adenosine, an adenosine receptor agonist, an adenosine deaminase inhibitor, dipyridamole, a monoamine oxidase inhibitor, digoxin, digitalis, lignocaine, a bradykinin agent, a serotoninergic agonist, an antiarrythmic agent, a cardiac glycoside, a local anesthetic, atropine, a calcium solution, an agent that promotes heart rate, an agent that promotes heart contractions, dopamine, a catecholamine, an inotrope glucagon, a hormone, forskolin, epinephrine, norepinephrine, thyroid hormone, a phosphodiesterase inhibitor, prostacyclin, prostaglandin and a methylxanthine.

6. The method of claim 4 wherein the drug is naturally occurring.

7. The method of claim 4 wherein the drug is chemically synthesized.

8. A system for performing a medical procedure, comprising:

a spinal stimulator to reduce pain during the medical procedure;

a nerve stimulator in communication with the spinal stimulator to inhibit beating of the heart; and

a cardiac stimulator in communication with the spinal stimulator to stimulate beating of the heart wherein the nerve stimulator stimulates a nerve from the group consisting of;

vagus nerve fibers, hypoglossal nerve fibers, phrenic nerve fibers, parasympathetic nerve fibers, and sympathetic nerve fibers.

9. A method of performing heart surgery, comprising:

stimulating a spinal cord to control pain;

stimulating a nerve to reduce the beating of a heart;

operating on the heart;

stopping stimulation of the heart;

stimulating the heart to cause beating of the heart;

re-stimulating the nerve to re-inhibit beating of the heart; and

continuing the surgery.

10. The method of claim 9 further comprising:

stopping stimulation of the nerve before stimulating the heart.

11. A device for controlling pain during a medical procedure comprising:

a processor;

a spinal stimulation electrode, the spinal stimulation electrode operatively connected to the processor; and

a nerve stimulation electrode operatively connected to the processor, wherein the processor processes output from the spinal stimulation electrode and adjusts output from the nerve stimulation electrode based on output from the spinal stimulation electrode.

12. The device of claim 11 further comprising:

a cardiac stimulation electrode operatively connected to the processor, wherein the processor processes output from the spinal stimulation electrode and adjusts output from the cardiac stimulation electrode based on output from the spinal stimulation electrode.

13. A method of delivering a baby comprising the steps of:

stimulating the spinal cord to control pain;

delivering the baby; and

stopping stimulation of the spinal cord.
