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 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.

2. The system of claim 1 further comprising:

drug delivery means for delivering at least one drug during the medical procedure.

3. The system of claim 1 wherein the drug delivery means are selected from the group consisting of:

a spray, a cream, an ointment, a medicament, a pill, a patch, a catheter, a cannula, a needle and syringe, a pump, and an iontophoretic drug delivery device.

4. The system of claim 1 wherein the nerve stimulator stimulates a parasympathetic nerve fiber.

5. The system of claim 1 wherein the nerve stimulator stimulates a nerve selected from the group consisting of:

a vagal nerve, a carotid sinus nerve, a fat pad.

6. The system of claim 1 wherein the spinal stimulator comprises at least one electrode.

7. The system of claim 6 wherein the electrode is selected from the group consisting of:

spinal stimulation electrodes, balloon-type electrodes, basket-type electrodes, umbrella-type electrodes, suction-type electrodes, guided catheters, guided electrodes, steerable catheters, and steerable electrodes.

8. The system of claim 1 wherein the nerve stimulator comprises at least one electrode.

9. The system of claim 8 wherein the electrode is selected from the group consisting of:

nerve stimulation electrodes, endotracheal electrodes, endoesophageal electrodes, intravascular electrodes, transcutaneous electrodes, intracutaneous electrodes, balloon-type electrodes, basket-type electrodes, umbrella-type electrodes, tape-type electrodes, suction-type electrodes, screw-type electrodes, barb-type electrodes, bipolar electrodes, monopolar electrodes, metal electrodes, wire electrodes, patch electrodes, cuff electrodes, clip electrodes, needle electrodes and probe electrodes.

10. The system of claim 1 wherein the cardiac stimulator comprises at least one electrode.

11. The system of claim 9 wherein the electrode is selected from the group consisting of:

cardiac stimulation electrodes, clip electrodes, needle electrodes, probe electrodes, pacing electrodes, epicardial electrodes, patch electrodes, intravascular electrodes, balloon-type electrodes, basket-type electrodes, tape-type electrodes, umbrella-type electrodes, suction-type electrodes, endotracheal electrodes, endoesophageal electrodes, transcutaneous electrodes, intracutaneous electrodes, screw-type electrodes, barb-type electrodes, bipolar electrodes, monopolar electrodes, metal electrodes, wire electrodes and cuff electrodes.

12. The system of claim 1 further comprising:

a processor operatively connected to the spinal stimulator, the nerve stimulator and the cardiac stimulator.

13. The system of claim 12 wherein the processor processes output from the spinal stimulator and adjusts output from the nerve stimulator based on output from the spinal stimulator.

14. The system of claim 12 wherein the processor processes output from the spinal stimulator and adjusts output from the cardiac stimulator based on output from the spinal stimulator.
